I see now. My first search of gavita yielded a plasma light they produce as well. I see the hps ballast and such now.

I'd go with Gavitas. I've yet to hear something bad about them or the E-Papillon.

those gavita ballast do have some hellacious heat sinks on them.
Large Bat wings?

Most ballasts do these days. If the ballast runs cooler, it runs more efficiently. From their website they say about 60W of heat, assuming 1000W through the bulb.

Really, the big thing I like about the Gavita, is that it has the ballast built onto the reflector. And that save you a significant amount of install time.

I know the exact model reflector that I would recommend and why. A wrong decision here blows your chances of achieving the results I detailed earlier.

If your ballast craps out?? I hate these.
Can't put ballast out of the room if you want either. Gavitas are overpriced junk imo.

With 400 lights, ballasts will fail.
Make thrm fast and easy to replace. No climbing over a tray to a hood. .. ewwww

Yeah, that is a good point for sure. If they were down around $400 would you find them more worth their while?

Nope. I would sell them if they were given to me. I have very specific lighting requirements.

That's what I figured you were getting to. And I assume your recommendations come at a price, is that correct?

for something of this scale...i would think everything has a price

Well you can experiment and go through trial and error. I've mentioned super hortilux and lumatek (no fan model). The choice of reflector is super critical imo.

I agree completely. And that is why I've spent a fair amount of time doing things like spectral analysis of bulbs with different ballasts, as well as photometric modeling of various reflectors in a program called Photopia. Sure, I could place a PPFD sensor at a ton of points on the ground, but having a clearer picture was important. However, I have not so far as modeled every reflector I can find. That's a lot of work, and I'm not done yet.
This is an emission graph of the Hortilux 1000W HPS though: http://i.imgur.com/F0vxUBs.jpg

Modeling reflectors in software is interesting, the nerd in me is intrigued. I am however more interested in modeling pot in reality.

Everything takes time and resources. And I'm getting to the stages where I feel I have enough information to start doing true scientific experiments on growing.

that first one is a little too skinny for me.
I like em with a little more meat on their bones.
