What is T5VHO vs T5HO?

um. actinics are the simplest bulbs to get in a major brand,, Phillips created the actinic bulbs for photocopiers. look for a Phillips 03.

PAR is not a complicated thing, don't make it into one. Yes it decreases as a bulb ages, and no you don't need a spectrometer to know if it decreases or not.

I never know Milwaukee made PAR meters, and the only decrepency in how to measure it are which units are the proper ones to use.. it is measured the same either way.

as for lumin, they are pretty much a usesless measurment to us I do own a PAR Meter ( And yes I do know how to use it) and have done long time tracking of PAR decrease in bulbs, while it is n't as much as one would thing there is a decrease over time.

I found some actual numbers a while ago that showed LUX output vs bulb temp measured at the cold end but I have lost the link. I had built my retrofit hood with some cooling fans and was taking the temp of the bulbs with an IR thermometer. IIRC without the fans I was was getting a little hot but it was costing me maybe 6% of output or something so I didn't run them often because of the noise. I think it's fair to say that the cooling has an impact but that some people overestimate the impact of it by quite a bit.

well, since Ice Cap doesn't manufacture ballast but re brands them we can assume one or more of the major manufactures makes a high output ballast so in reality any of the companies could have access to them. Personally I won't even own a Ice Cap product, even if it was free.

Sorry buddy you're going to have to back that up.

I've got a model 660-009 that I opened up to replace a capacitor sitting on my desk right now. Not only does the PCB have IceCap industries printed on it two of the transformers have part numbers that start with ICE.

This is not an OEM ballast in a blue box.

let me refrase this, they were taking ballasts and repotting them in there cases as with the older 660 (i believe it was) it was two HO ballast in one box. now this was also 8 years ago I believe, so maybe they make a few things now, but really from a economical stand point for the amount of ballast they use it wouldn't be cost effective to make there own localy, but maybe there are having them made now who knows a lot can change in 8 years, but I would still never own one.. it isn't because of the product but because of the owners and the way they used to do buisness, can't say if they still operate that way but I don't care lots of cheeper stuff that is just as good if not better out there.
