That looks sweet, but not sure I like the idea of ballasts built into the hood, I prefer remote. Also are the ballasts themselves any good?

Can the ballast be separated from the lamp?

Yes. But it requires a complete disassembly - removing inner reflector to gain access.
Can't speak for reliability or quality of ballast. Not a huge risk when a 315cmh ballast alone cost is $100+.
The biggest draw for me was the 18x18 opening, and vertical bulb. They run really cool.

Neat. When growing vertical, do you also use these vertical sockets?

I used these bulbs (or the rebranded equivalent), IME they seem more prone to failure than Philips bulbs over time. I haven't had a philips bulb burn out and become unusable. I'm sure it happens, but with these it happened twice to me. maybe it was just bad luck. One of them burnt out after only 3600 hours of use :/
Anyway, I'm not trying to sound like a party pooper. My experience is just anecdotal. Maybe someone else can chime in. 315 bulbs from different manufacturers all performed quite similarly in the tests I've seen.

I just take the Nanolux lamp apart and use it, I bought two of the cables like the ones in the Phantom Kit, but just the cable for my assistant.

I just picked up a 4x8x6.5 tent for flower only and need to grab some lighting. Also, I need to keep heat down as I don't want to run AC.
Right now, running 620w of Aglex lighting and tent is getting up to 81 with exhaust running full blast. Problem is....thats only lighting one half of the tent. Once I have the tent full on both sides...I'd never be able to cool it down.
So, I've been considering all options and am leaning to CMH because they seem to work well and cheaper than quality LEDs. I'm trying to keep my costs down to keep the wife off my case lol.
I was looking at the SilberStar 315 vertical hood with the separate ballast and Philips 3100 bulb for about $400 delivered.

Figured I would get two and watch the heat. If it's manageable...get a third one and have a decent light overlap. Or I could throw in a one of my LEDs in between them with only the bloom switch running.
I'm running a 6" AC infinity fan and 6" carbon for exhaust. Also have a 6" fan for intake when it gets too hot.
Any idea of how much heat buildup I can expect with 2 or 3 in a tent this size?

Never had a 4 x 8, only 4 x 4's.......But I'd think with a few variable speed fans in there you would be fine. Ummm.....negative pressure is best, if using a 6" exhaust (I use one in a 4 x 4) Id use a 4" intake fan.....you want more exhausting, ideally. For a 4 x 8 tent Id want bigger then a 6" Exhaust.....
8" exhaust and then utilize the 6" intake. Another config

Thanks Couchlock. Exactly another issue I'm having. I'm getting positive pressure because even with the 6in intake dialed down to the lowest speed...it's pushing more than the 6" with carbon filter can exhaust. I have a 4" that I can try in place...or one of those 6" duct fans.
I'll probably have to switch up to an 8" but it'll have to wait until spring so I can do the venting work at the wall.

Ive had a rough start myself this winter.....had used my CMH's previously last Jan, bought an HLG 550 V2 Rspec last summer and that 2nd 2019 run was pretty good.
So I started my Jan 2020 grow (I live almost as far north as Canada) with the LED......in a 63 degree cellar Ive seen average temp highs at 71....thats not enough, the stems are spindly AF so far. So, I unplugged the LED light and tossed in a CMH.....my humidity rose 10% in 3-4 minutes......temp rose 4 degrees in that time frame also (keeping the ballast IN the tent for warmth).
Plants are about 9-10 days old.

I need the heat, its where I live. Ballast must be inside for winter grows.

I've got mine in a basement bedroom but I have a furnace duct that I can open if needed to warm room in winter. But I've got it right closed now.
In the summer I have central air which helps but if I turn up the air too high then other in the house are complaining it's too cold. Lol

You are all set then on temps...Once u hit your sweet spot on exhaust vs intake you will be perfect.
