Does anyone use VHO lighting for their tanks....I have an Icecap 660 that I used on my 100 gal reef tank...swapping over to Fresh. Is this adequate? Dimensions 20"x20"x60".

Seems that not many people run these...are VHO's too bright? Also...want a set of bulbs that can grow plants adequately but also really show off the colors in fish! Remember this is a VHO ballast and can only run VHO lights!

Thanks....

PS Rex Still have all your emails and such....tank up and running with substrat just cant figure out how to freakin load a smaller pic...LOL.

Regards!

I use VHO for my 6 foot tank. Best bang for your buck (at least in Canada)

Same rules apply for VHO as they do for any other lighting for planted tanks.

I'm not too familiar with the Icecaps (except for their reputation) so how much lighting are you actually looking at putting over your tank?

VHO lighting is less efficient than regular fluorescents or PC lighting. That is, you get more heat with the same light output, or less lumens per watt. I think this is the main reason why it is not used more.

You don't need to run VHO lights with an Icecap ballast. You can "overdrive" regular tubes, which should be a bit cheaper when replacing lamps.

At lengths of 48" or more VHO is substancially cheaper then regular Flourescent or PC. Bulb replacement cost is only marginally higher on a per bulb basis and you get about 4 times the light output. The bulbs are quite hot, but no more then an OD'd regular flourescent bulb.

On a 100 Gallon tank I'd probably run a pair of 60" VHO's, so about 280 Watts, maybe 3 (so 420 watts). Although you will need some pretty spectacular cooling/venting if its a closed canopy.

I used to run 3 x 160 watt tubes over my 135 Gallon tank but I couldnt keep my place cold enough and all of my tanks were overheating (not to mention I was somewhat uncomfortable all the time)

There was an article in FAMA about that stuff, might be interesting reading for some of you http://www.icecapinc.com/rev1.htm

There are so many ways to heat a house :lol:

I cant run 60" bulbs...have to run 48" due to hood restrictions.

any suggestions?

Any suggestions for types of bulb...etc.

For example...color spectrum (Kelvin?)?

Thanks

You should take a read through the "OD'ing a 125 Gallon" thread, it has some good information that is relavent to your quests here.

Ok so here rests my ???

Just spoke with Marcel....I have an Icecap 660 that will power 16' of VHO bulbs.

If I use GE Aquaray at 40 watts per bulb (48" T12 9325K)...and I use four of them on my system what would I be getting for a WPG on a 100 Gallon tank?

If indeed the VHO "overclocks" the bulbs then this is the way to go I am thinking!

Regards

Hmmm... thats a toughie.. I do not know how to wire this ballast to OD NO Flourescent bulbs.. but if you do the quick math (I looked up the specs) the ballast would "try" to push up to 110 watts of light into each bulb. I do not know how well this would work for typical 40 watt bulbs.

I'm not the best person to ask about this one I"m afraid..

Gareth, That was my reasoning exactly. He'll hook up the t-12s to the icecap and get 110 watts per bulb , this would be like ODNO 3x..

From what sam has said in the ODNO board, VHOs are just a t-12 beefed up to handle the extra wattage, and they don't produce more light than a reg t-12. It's all about the wattage.

According to the article I posted earlier, with an Icecap 660 you can drive 4 48" bulbs to 80W each. So you would end up with 320W... and very cheap bulbs compared to the VHO ones.
