Low Output Ballasts?/Lighting 8/18/09
Hello everyone,
<Hi Mark>
I recently purchased a VHO ballast and VHO bulbs for a frag tank which I
grow corals in to sell to the LFS to help finance my addiction to the
hobby. The output of the new bulbs didn't appear any different than the
standard 40 watt ones I was using before, so I checked the wattage with
a meter I own. It is one of those that just plugs inline on the power
cord.
It is dead on when I check my metal halides or T-5's on my main tank. It
says the ballast is only putting out around 90 watts total (45 per
bulb), far below the 220 advertised. It also tests for amperage and it
is down considerably as well. They are definitely wired correctly as
they were bought as a retro-fit kit from Hello Lights. They are clueless
about what the problem could be and said if they light up there is
nothing wrong with them. I disagree.
<What you are reading on the primary side of the ballast isn't
indicative of the power the ballast is supplying to the lamp itself.
A magnetic ballast works something like an inductor, a coil of wire in a
circuit which may be wound around a piece of metal (core). When current
flows through the wire, it generates a magnetic field. Positioning the
wire in concentric loops amplifies this field, and the ballast in tandem
with a transformer controls the amount of current going to the lamps.
Newer ballast designs such as ARO's, use advanced electronics to more
precisely regulate the current flowing through the electrical circuit.
Since they use a higher cycle rate, you don't generally notice a flicker
or humming noise coming from an electronic ballast. Do not compare your
current readings to MH and T-5 lighting. Different lamps require
specialized ballasts designed to maintain the specific voltage and
current levels needed for a particular lamp. If the ballast were
defective, you would likely see flickering, or no light at all.>
Is it possible they are selling cheap ballasts not really putting out
what they claim on the packaging?
<ARO is a reputable brand of ballast, the 220 watts/1.82 amps, strictly
refers to the maximum power/current the ballast is capable of handling.>
I always had decent luck in the past with them so I'm not criticizing,
just wondering if ballast brands could make that much of a difference.
<Unlikely.>
The brands and specs are as follows: ARO electronic ballasts model
AS-220 and URI T-12 48" VHO bulbs (110 watt each). Have you heard
anything negative about either of these brands?
<No.>
Any advice you can give to what may be the problem would be greatly
appreciated. Your site is a huge benefit to the hobby.
<As above.>
Thanks again.
<You're welcome. James (Salty Dog)>

PFO ballast convert PC to VHO 12/28/08 Hello, <Hello
Lenny. Minh at your service.> I currently have a 55gal (48 X 17 X
15)reef tank I purchased from a friend who came over and set it up the
way he had it. The pumps that I am using are RIO 17 HF for the return
(he had a Gen-x 4100. I couldn't stand the noise from that thing so it
was changed) and a Gen-x 1000 for the skimmer. The lighting is a
PFO-EL 2-2 ballast running 2 33" 96 watt PC 50/50. This canopy setup has
the PC's 8.5" above the top of the tank. I would like to change to VHO's
which this ballast is capable of. The main concern for my choice to do
this is my tank seems to run on the warm side around 82 and that is with
2 fans in the canopy and one more in the sump. I've read and was able to
feel myself that the PC's ran hotter than the VHO's. <This has also
been my experience.> I have searched for the quick connects that are
already wired to the end caps with no luck. I have emailed PFO and was
told basically sorry, we don't have any but good luck. I can find some
3pc T12 end caps through aquacave.com(thanks to your site) but can not
find a wiring diagram for my ballast. <From my research, it appears
that the PFO-EL 2-2 consists of a PFO enclosure and Fulham Workhorse 7
ballasts. You may need to open up the ballast enclosure to verify this
information. The Fulham Workhorse 7 ballast wiring diagram can be found
here: http://www.fulham.com/Find_Process.php.> Also, not sure
how long the bulbs would need to be if needed to be longer than the
current bulbs. <The Workhorse 7 is capable of running up to 220W. You
can review the specifications on the VHO bulb you are interested in
running for the optimal power/length configuration for this ballast.>
Any ideas or suggestions would be greatly appreciated. <If the above
suggestion does not pan out for you. You can also contact the folks at
DIY Reef (http://diyreef.com/shop/index.php) or HelloLights
(http://www.hellolights.com), they are both very knowledgeable in
fluorescent lighting.> Lenny <Good luck. Cheers, Minh Huynh.
Re: PFO ballast convert PC to VHO 12/30/08 My previous
email to PFO, finally they sent back an answer that was more helpful.
They replied that my ballast uses the workhorse 5 which I confirmed once
I opened it. After your response I went to the Fulham website to look
for the wiring diagram needed for the type of bulbs used. They only
show for the workhorse 7 or 8. Do I still use this even though this is
not my specific ballast? <After reviewing Fulham's website, it
appears that they only recommend the Workhorse 5 ballast be used with
certain bulb combinations. For example, when using their diagram tool,
"T5 Linear HO with a bulb set 2xF24 HO" will give you a Workhorse 5
wiring diagram but not with the T12 VHO bulb combination. It is best to
err on the side of caution and contact Fulham to get their full
recommendation on what you'd like to achieve with the Workhorse 5 and
VHO combination.> Lenny <Good luck, Minh Huynh.> PC
Ballasts Going Bad 9/12/08 Hello all, long time no ask :-)
Hope the members of the wet web crew are all well. <As far as I am
aware, yes.> I have a 65 gallon reef tank (18" deep by 36" long by
24" tall). I have a 4x96 power compact lighting fixture from a well
known lighting vendor providing the light for the tank- I will omit the
name. I run 4 different types of bulbs in my 4x96 - 10,000K daylight,
6700K daylight, 420nm and 460nm actinics. I try to change them about
every nine months (thanks to your advice, I stagger the change out of
bulbs, to not shock the corals). Last year I lost a bulb, and when I
went to change it out, realized after the new one failed to work, and
swapping some bulbs, that I had a bad ballast. <Dang!> I
purchased a new ballast, and installed (not too hard, just a pain to get
to and get all the wires packed back in). About a week ago, I lost a
bulb again (I don't exactly remember, but I'm fairly certain it's not
the same ballast). Turns out I lost another ballast. My question is, do
you feel that this is fairly common, because it's extremely frustrating?
<Definitively not unheard of, but not an everyday occurrence either.>
The light itself is about 2 years old. I think it's ridiculous that I've
lost two ballasts already. They are not cheap! <Nope.> Not sure
if I'm doing anything wrong. The light sits directly on top of my glass
tank lid. The light came with legs for the light canopy, but the
instructions also stated that the legs were not required and that the
light could sit on top of the tank. The fans in the light housing are
operating. I have my actinics on for about 12hrs per day, and the
daylight lamps on for around 11 hrs. They are on an automatic timer. Any
thoughts? <A few, first you could just chalk this up to plain old
dumb luck. But, two things to look at that may help. First, I would
raise this fixture a bit (just 1” or so) to allow some air circulation
around the entire fixture; maybe even a small fan blowing on it if you.
This will all of course keep things a bit cooler. The other thing you
should look at are any signs of corrosion/moisture inside (or outside,
it is indicative of the moisture getting to it) the fixture. This can
drastically limit the life of a ballast, or even flat out kill it if the
moisture makes it to the wrong places.> Thanks, I owe my healthy tank
and coral success to your website and the amazing information within.
<Awesome!> Chris <Welcome, Scott V.>
Mounting locations for ballasts in a canopy 7/24/08 Hello WWM
crew, <Hello Leslie!> Thank you for the wonderful service you
provide to us fellow hobbyists! I hope you can provide an answer to
my questions on lighting and ballast location. <I am sure we
can.> First, a little background. I recently purchased a 75
gallon tank (48" L x 18" W x 20" H) with stand and canopy to upgrade
and consolidate my current 29 gallon and 14 gallon systems. I only
have Mushrooms, Xenia, and Zoanthids, with no plans to advance to
SPS or LPS at this time. I have purchased 2 (2x54W) T5 retrofit kits
with individual bulb reflectors, 2 AquaBlue+ (15K) bulbs, 1 pure
actinic bulb, and 1 actinic+ bulb (all Giesemann brand) and two blue
LED moon lights to install in my canopy. A picture is attached to
show the inside of the canopy with the lights in approximate place.
<Looks nice.> I plan on purchasing two cooling fans to be
installed on the left inside of the canopy as well. <Generally a
good idea.> I understand that ballasts should be mounted away
from water, and if mounted inside the canopy can contribute extra
heat above the tank. <Not to mention moisture accumulation on
the ballast, leading to corrosion or worse.> The lights don't
leave much room inside the canopy for ballast installation anyway!
Is it reasonable to mount the ballasts on the outside lip of the
back of the canopy if the wires will be covered by wire loom?
<This is actually where I mount my VHO ballast. Just a few
precautions doing this. First, use something waterproof at least on
the wire connections, something like the common black electricians
tape. Next, do form a drip loop. You do not want any moisture
accumulation that may happen to lead back into the ballast or the
electrical plug it uses. Your fans will help out here too, keeping
fresh air moving through, preventing some, if not most, of the
condensation. Last, keep an eye on it! If you notice any moisture on
the ballast you will need to move it, and by all means, unplug it
before you touch anything. > This lip is about 2.5" tall, and
just fits the ballast size. If that location is not recommended,
what would be my next best (and safe) option? <Ideally the
ballasts should be mounted away from any moisture. Not in the canopy
or stand. A lot, if not most, do anyway.> My local reef club
lighting gurus recommend mounting them on top of the canopy and
covering with a homemade "top", but I prefer a seamless look on the
tank. <This is a good mounting option, but I too do not like
having anything showing.> Thank you again! Leslie in sunny
Florida <Welcome, Scott V. in overly sunny California.>
Re: Mounting locations for ballasts in a canopy 7/26/08 Hello
again WWM (Scott V), <Welcome!> Thanks for your prompt reply
to my question about ballast mounting locations! One more quick
related question: How far away from the back wall should the
ballasts be situated to safely prevent overheating or melting of the
paint from the wall? I would think at least 6 inches, but that
leaves a pretty large space at the back of the tank. If this proves
to be the case, I will probably mount them remotely at the side of
the tank. <Ah, for these ballasts an inch or two will do. The
fact that you will have exhaust fans in the canopy will keep things
at a reasonable temperature. I assume you will have them blowing in
and flowing out the back where the ballasts will be? Even if you
have the fans blowing out of the canopy, air will still flow over
the ballasts.> Thanks, Leslie <Welcome, have fun, Scott V.> | .JPG%20mounting%20ballast.JPG)

Full spectrum fluorescents and electronic ballasts Dear Bob,
<Howdy> Greetings from Central Indiana (land of pig farms and redneck
sports). I have been thinking of using a normal output, full spectrum,
fluorescent lamp to simulate morning and evening lighting periods over
my aquarium. In reading your lighting article, you greatly recommended
the vita-lite ( among some other, more commercial brands ). <Need to
modify the article, thanks for reminding me. The manufacturer, Dura
Corporation, is out of business> I happened to stop by Menards on the
way home to see if I could find some of these more commercial brands
that you listed. I found a Westinghouse ReaLite model 36516 with a CRI
of 98 and 6500k. It is used to treat Seasonal Affective Disorder (SAD).
<Neat! I use such lamps on my photographic light tables when away from
the tropics too long (or spelunkering). Really cheers me up> Anyway
the lamp was 8 bucks. Do you know of any who have experimented with this
lamp and if so, do they keep their color and intensity? <Should be
fine for the intended use> Also you mentioned the ability to use H.O.
and VHO ballast formats with N.O. Tubes. I have had my eye on the Ice
Cap 440 and 660 electronic ballasts but their kinda salty (no pun
intended...) Do you know of a lower cost, true electronic ballast that
will match the Ice Cap's performance? <Unfortunately no... Bear and
grin with Perry.T at Champion is my advice.> Thank You Greatly, in
Advance. jS <Be chatting, Bob Fenner> VHO Ballast
Good morning WWM staff. Once again, I have a question that is burning a
hole in my mouth. <Most of my questions revolve around burning a hole
in my wallet.> I'm in the planning stage of a DIY lighting project. I
have a 24" deep 120 gallon FOWLR that I would like to add some soft
corals and anemones to. <By anemones, I am hoping you mean mushrooms
anemones or colonial anemones/Zoanthids and not clownfish host anemones
as these are extremely difficult and I, in good conscience, can only
recommend them to individuals dedicated to unlocking the secrets to
their success.> Would the IceCap 660 ballast work for this tank?
<Yes, you would be able to grow some soft corals, mushrooms, and
polyps.> I haven't found much information on it but it sounds like it
should put out 96x4. <I think you are a bit confused with the
terminology. Your subject was VHO ballasts but the wattage you
described, 96 is typical for Power Compact/Compact Fluorescent lamps.>
Assuming this will work, what type of bulbs would you suggest? <2-3
full spectrum lamps with 1-2 actinics.> How about two 20,000's and
two 50/50's? <Ok, but I prefer to use the spectral analysis provided
with some lamps to make my decision vs. color temperature or other more
marketing directed terminology/descriptors.> I'm not a huge fan of
the super blue tint but I know that it's necessary. <We have a
tremendous number of FAQ's in regards to lighting issues on
www.WetWebMedia.com I would advise you to continue on in your education
and read some of them.> Thank you. <You are welcome. -Steven Pro>
VHO Ballast Hello, I am shopping for VHO lighting for my 125
gallon salt tank. I've arrived at having to decide between Icecap from
Champion Lighting & Supply or for about $70 to $100 cheaper Hello Lights
brand from hellolights.com. I've seen the many posts citing Icecap as
reliable. Also, I've seen www.WetWebMedia.com staff praise the customer
service (not necessarily the product). I can find nothing about the
Hello Lights. Are electronic ballasts pretty much equal, or would I be
taking a sizable risk with the off-brand ballast? Do you know anything
about these Hello Lights ballasts? <I have no experience with Hello
Lights. I would ask your fellow hobbyists on the message boards for
opinions/feedback.>:

Pro> Fluorescent Ballast Question Hello WWM Crew,
Over my 55 gal tank, I have a 2 light 4 ft fluorescent shoplight. I
have a few plants, a few fish, and it's doing ok. It's running on an
ancient magnetic ballast. Never had a problem with the ballast until I
started using some of the newer T12 bulbs. In the past the ballast
would hum when the lights first turned on but would eventually settle
down. With the bulbs I'm using now, the ballast hums as long as the
lights are on. The hum isn't too bad, can't hear it over the TV. My
problem is I've discovered the lights aren't as bright as they
could/should be. I have a 24 inch fixture that's using a 2 foot
version of the same bulb in the shoplight and it's much brighter. I'd
like to put a T8 ballast into the shoplight, but I still have at least a
couple year's worth of T12 tube's. It's also easier for me to find
5000K and 6500K bulbs in T12 version at my local hardware stores.
Until T8's become a little more common, I'd like to be able to make use
both world's. Have you had any experience with the combo ballasts that
claim to run T8's and T12's? None of the light shops I've spoken to
sell them, but they've heard of them. Thanks for your help, Lewis
<Sure, you are talking about Ice Cap 660's. They will drive anything
from compact fluorescent to VHO and also NO T-12's. I imagine T-8's
could be wired in as well. Check out the lighting section of any of the
wetwebmedia.com sponsors that carry hard goods. Champion lighting has
the most info on driving regular NO T-12's on Ice Cap ballasts.

WWM Crew, I am trying to decide whether or not I should replace my
bulbs or possibly need to replace my whole light fixture. The unit I'm
confused about is a CSL 4 x 55 watt ABS hood( 2 8800 daylight + 2
actinic). I bought it about 2 years ago and it was a used unit in good
condition, so I really don't know exactly how old it is. I had been
using it on a 90 gal reef tank that I just had a custom oak canopy made
for with 4 x 110 watt VHO lighting, so I was now using this light on my
55 gal tank. Well I realized my bulbs were due to be replaced. And as I
was looking at the tank (55 gal mini-reef) it appeared that the left
half of the tank seemed to be just a little bit brighter than the right
side. I thought well that's because the bulbs just went past a year old
and they need to be changed. Just to be sure it was a bulb problem, I
decided to swap the bulbs on the left to the right and vice-versa. I was
sure that now the right side would appear to be brighter. However that
was not the case, the left side still appeared to be brighter. Then I
thought it must be because the overflow box is on the left side or the
LR is at an angle that reflects different, so I picked up the whole hood
and swung it around 180 degrees and now the right side was indeed
brighter. Also just to be sure this was not being caused by a dirty
piece of plastic, I slid the plastic lens from the bottom of the
hood. Still no change the left half of the light is definitely a little
brighter than the right. So my dilemma now is whether or not it's worth
spending 100 dollars on new bulbs when there must be a problem with the
ballast on the right half of the unit. I know bulbs are always in need
of replacing but I've never heard of people replacing ballasts, nor do I
know if that is even possible in a pre-manufactured ABS hood. <It is,
you just need to disassemble it.> I would greatly appreciate any thought
you might have on this matter. <Well... my thinking is in line with
yours, that typically ballasts have a lifetime of at least ten years or
better. Most modern ballasts are solid state so there's really not much
that can/will age, but will instead just crap out. I'd at the very least
pop some email to Custom SeaLife to see what they think about the whole
thing.> Thanks again for your help, Kevin <Cheers, J -- >
Buffering/lighting Hi Bob, My tap water does not have a lot of
buffering capability. <Do you need, want more? Can be augmented
easily> When I do my regular water changes (7 to 10days), the tank
water has a pH of 7.8. I use Instant Ocean Salt and my replacement water
has a pH around 8.2. I believe that the shift in pH after water changes
is stressing my system. <Good point.> I have started to use Kent
Marine's Super Buffer and now my pH stays at 8.3 and. Alk = 4 mEq/l.
Is this method of keeping up Alk/pH up a good idea or would the two part
supplements be a better choice? <Two part would be better.> I did
read the article in FAMA as requested by you about the Ice Cap ballast
running NO fluorescence. I remembered reading that article years ago and
another (same concept) with a plant tank. It really sounds like they are
having tremendous results with NO tubes and VHO ballast. My main
question here is with tube replacement. Ice Cap says 6x longer life. The
recent article in FAMA state that regular replacement of the tubes have
been unnecessary. Also in FAMA with the other article on the plant tank
he state that he has been running the same tubes for years. Now what
puzzles me is that this is exactly opposite of what most say. Hmmm?
<The use of electronic ballasts in these cases does extend effective
lamp life as far as I'm aware, but don't know about six times,
definitely not indefinitely. You can test for intensity, spectral
make-up over time... or just observe your plant livestock for changes.
Bob Brad Lighting Question Hi Bob or Anthony,
<tweedle-dum here...> Another quick question: (I got such great
advice the first time I figured I'd pester you folks again). <we make
half of the stuff up, but it's convincing> If I was going to upgrade
from standard fluorescents to HO or VHO bulbs <no HO...a dying
technology. VHO or Power compacts please> would it be possible to get
a strip light fixture from a place like the Home Depot to operate them
in? <a reflector yes, but nothing else. Need specialized end caps and
ballast> And would I still need to invest in a good ballast too?
<yes... and Icecaps have good customer service> I figure the brighter
light would not only be great for the fishes but also for casting some
cheer during the gray winter (Feb.'s the worst on the east coast).
Thanks guys. "Warm" regards, Adam <alas, an expensive but worthwhile
investment. Cheers from "sunny" Pittsburgh PA. Anthony>
Fluorescent lighting question I tried to read the Fluorescent
lighting FAQ section on your web site but it's not coming up. The PC FAQ
is, just not the Fluorescent page. I've seen that in a few other areas
but I'm remiss in mentioning them to you. The frames and banners all
load, but the content does not. There are no error messages. <Some of
the article pages are not complete and merely have a link with no
content, but all of the FAQ pages should work. I looked at this page has
a bad link. The FAQ for fluorescent lighting is here
http://www.wetwebmedia.com/fluoltgfaqs.htm> At any rate the question
I have is a pure DIY question. I'm building a new canopy for my 80
gallon long aquarium. The tank is currently dry but should be full of
water in a few weeks. The tank is 6 feet long with one opaque divider in
the middle. I intend to put a glass top on under the canopy. Now that
you know my parameters I'm looking into just using a 4 bulb 40W
electronic ballast from Home Depot to power 4 36" 36W lights. As I
recall if the bulbs only need 36W there is no problem with using a 40W
ballast. <Yes, most of these ballasts will run 40 or 30 watt lamps.>
I intend to use two full spectrum and two actinic bulbs on a FOWLR tank.
(Alternately I may add a second two bulb ballast and run the actinics in
there for sunrise/sunset simulation on a different circuit.) All of
that said do you see any potential problems with the setup? I can buy an
Icecap setup for about $120 or I can build my setup for about $25.
-David Rencher <Do be sure to use water resistant end caps, plastic
junction boxes, and follow all applicable safety codes for electrical
work. -Steven Pro> Tar vs. Electronic ballasts Good
day, Can you tell me the difference between a tar ballast and the other
types of ballasts? << Sure, but in simple terms because I don't know
much about them. The other kind of ballast is an electronic
ballast. My understanding is that an electronic ballast will run all
bulbs (of a certain wattage) but a tar (also called a coil) ballast will
run some bulbs but not all. However the main difference is that a tar
ballast is way stinkin' hot and will burn you after has been on for a
few hours. An electronic ballast is so much better. I have them, and
can't imagine using any other type of ballast. I only recommend
electronic (although they are much more money like $150 USD as opposed
to $50 USD). If you want more in-depth info please write back. >> Which
is better? << Blundell >>
