They both have UV. I use the single jacket for less light loss through the glass.Thank-you gentlemen, which bulb is better? The T12 has UV and T9 doesn't and both bulbs have same voltage.
I am so unimpressed by my sun system 315. To claim it can replace a 600 straight up, is a damn lie IMO.Careful with sunlight supply lights. I've heard they don't have Phillips ballasts and there for do not fire the 315s to their full potential. Don't know if that's fact though. Never opened up a Sun system case.

At one of our smaller grows we are consistently getting at minimum a pound a light, 1.5 to 2+ grams per watt. Minimum. We're pretty happy with that. We think we'll do even better at this facility just because of the shear volume of lights in our rooms, so much cross lighting.I am so unimpressed by my sun system 315.

We have people coming into the hydro shop on a regular basis changing out 2 1000s for 3 315s and claiming the same weight. I've come to the conclusion it's not the light itself, it's the fact these people can now actually control their environment instead of fighting the 1000s. unfortunately as of right now, these lights have no place in my garden.
The way I describe that light now, 400w growth rates with t5 node spacing.
I too am pulling a lb from each, but barely. GPW wise I am doing the same as I was with DE 1000s. Slightly better GPW than what I used to do with a SE 600. For me I don't see any savings, just less production with a smaller power bill. I'll be doing another run or two with them, but need to get them to pull what my room was before for them to stay.At one of our smaller grows we are consistently getting at minimum a pound a light, 1.5 to 2+ grams per watt.

ya enlighten me alsoWhat is a 315 exactly?
Uh... I'd just read the last 20 or so posts and that would answer that question! Happy growing!ya enlighten me also
Light quality. 96 CRIHey from what I read I think this thing puts out less lumens compared to my 400watt. What's so special?
