If you want to use an existing reflector, just swap out the sockets. I'm using the Bell Lighting 600MV hoods, and they work great with the 315. The lamp is almost perfectly centered in the hood when installed.

Seriously. This thread is full of great information that is absolutely necessary for making a CMH/Ballast/Reflector purchase. However it is a nightmare to have to read thru this mess. I'm sure someone who is knowledge would be able to consolidate this thread into 1 post, making it much easier for people trying to figure out what they need to buy and from where it is available.
^^^Let's get it all sorted out first lol. We're all trying to help each other out atm.
The 120v ballast kit from advanced is foreign to me. By looking at the pics, it does just look like some kind of step down on the existing Philips 240v ballast. I was told it works well. They're just tweaking/deciding on a minor "switch". Shouldn't be too long of a wait. If you want details you can call the number on site.
DNA has a nice little 330w 120v electric ballast, socket, and bulb kit for $380. I'm just going to wait for the advancedtech ballast.

Why worry. He points out that a 1500W step up transformer will easily run 4 ballasts, and is about 40$. I think he includes it for the 220$, right?
So why mess with a totally new and unproven ballast?

In looking at picos reflector thread https://www.icmag.com/ic/showthread.php?t=51325&page=65
habeeb measures less than 2% PAR loss for a sheet of glass. So I am back to thinking about the T9. Something like the SS2 with glass, and the T9 bulbs for 10% more light efficiency (-2% overall).
Critiques?
I really wish I could DIY a 4 sided parabolic vertical fixture with that 98% reflective aluminum and passive cooling vents. Single stamped sheet you bend tabs up and bolt the 4 together. Buy a sheet of tempered glass locally. Cheap to ship flat. One part so cheap stamping. Do a group buy... Perhaps add a PGZ socket
Anyone interested???
No shit...I was never told about this option. I ASSumed a step up would be expensive. I doubt it's included, but I'll check. I'm going to rep the shit out of you
I do remember him telling me about wires getting hot, maybe that's the reason. And/or it's a cheaper option.
I really like this site for the 315s http://www.ecat.lighting.philips.co...-cdm-t-elite-mw/21299/cat/#productFound_Label
You can click n compare the T12s with the T9s? (single glass). The single glass is more intense, has a longer life, use diff bases, and diff UV.
What really interests me is PGZX18 vs PGZ18...either have an edge? What do you guys think about UV comparison?
I know this is a CMH thread, but I came across an HPS I've never seen. Incredible PAR, price, intensity, and longer life. It seems like one of these bulbs would beat out two 315s. http://monstergardens.com/Grow-Lighting/Bulbs-Grow-and-Bloom/Genesis-Bulbs?product_id=2270 Opinions?

I just registered in this forum because apparently this is the go to place. For CMH it dominates. So I ask if anyone is familiar with the product sold by HTG Supply, a 400W CMH grow light as such:
http://www.htgsupply.com/Product-HTGSupply-400-Watt-Ceramic-Metal-Halide-Grow-Light
Specifically, why does it look priced on the low side?

Here's a nice little sale http://growershouse.com/sun-system-lec-315-light-emitting-ceramic-mh-fixture-120v

why not just get the ATL 220$ kit and buy you fave reflector and save 100$?
That is a pretty intriguing fixture. There are a couple of people that I know of on here using it with good success - it would be very interesting to map the consistency of the light output over it's footprint. The vertical lamp orientation should give it a marked advantage in an even light distribution.
I'm going to call growers house. They do some awesome reviews, and I'm sure they can give me every PAR reading with that fixture. I agree with a vertical hood advantage over horizontal.
I really want the 120v kit they're 'working on'. I'm selling my 860w, so I need something ASAP. I'm still waiting on a reply from them. I don't want to go the step up transformer route, when the 120v kit will be a comparable price.

Ya. But could one not just have a local tin basher cut up some tin trapezoids and glue Mylar over them, and get pretty much the same thing?
A couple of things to bear in mind with that fixture is that, since it is open, you cannot use the T9 (single-jacket) lamps in it and you don't have the capacity to duct the heat out directly.
Good point. I wouldn't mind a T12 at all tho. Heat won't be much of an issue with that fixture and bulb.

if you want to get a hold of tom call him.
If you have to move NOW then
And why not just get a step up transformer http://www.amazon.com/Seven-Star-TC1500W-Step-Transformer-1500W/dp/B000AY3JEK
that should support 4, or 5 if you push it.
And then just get as many ballast kits as you want from tom, and his ballast and bulb combo price is still great. Also he has the PGX bulbs, but don't tell him I told you.
They design these hoods for optimum and even light distribution. Look at the OG and Luxor hood reviews.

I am not saying they have not been designed well, I just don't think there is much to designing them well.
Also i Don't like the ballast built into the fixture, as its not supposed to get over 85C
