Scott, if you read this, why is it again you like URI bulbs? How often do you change them out, and what kinds of livestock have you been able to successfully (color + growth) keep in there? |
I like the URI bulbs mainly for how the tank looks. When I first started out I used some T8 bulbs I picked up at Petco. I don't even remember what they were now. Once I found GARF and started using the URI VHOs I never looked back. I truly believe I could keep any coral successfully in the hobby under VHO lights if all other conditions are met.
When I first started to switch over to VHO I used two Hamilton magnetic ballasts. I would change the bulbs out every 6 to 9 months and I could see a slight change in intensity when I changed bulbs. When I changed completely over to VHO, I ran them on IceCap 660s. If I change bulbs at 18 months I can not see an intensity change. I have been low on funds over the last year so I waited 24 months before changing bulbs. There was a very large intensity change. If possible I will change at or before 18 months.

Be fair and biased, please, what are any disadvantages? |
The bulb diameter is a disadvantage. There are more effective reflectors for smaller diameter bulbs. This allows more light to be reflected into the tank.
I have kept clams under VHO but I do not think they thrived.

Are workhorse ballasts 'good' for VHO, or just 'good enough'?

If the ballast is rated for ~1500mA then it should be good. IME, bulbs last longer when fired with electronic ballasts.

What materials are best for reflectors? Can I just wallpaper the inside of my canopy with tin foil? |
I just paint the inside of my canopy/hood white... Not the best ,but once I cram all the lights in, a reflector is not very effective anyway.

For those of you who do DIY VHO, do you buy things locally, do you do a commercial setup, or do you just kind of pick and choose from the web?

I am pretty anal about buying locally. The only time I order over the Internet is when I can not get it locally or if I needed it yesterday and can't find it locally. I build my own canopies and hoods then wire the lighting...
I have a new hood design that I an building a calculator for. It is very simple and easy to build. I put the last one I made on my 150 gallon tank and it is split in the middle so the front will fold over the back when a larger access is desired. I should take a picture of it an post it...
Thanks,
