I don't think there's any lighting tech that can hold a candle to vert bulbs in a proper layout...so long as you don't lose your crop.
what g/w are people getting from these? I can consistently take 2g/w from standard MH/HPS lighting when I grow vertically I just wondered how these compare.
I only grow personally so 1 600w lamp provides me over 40oz every 11 weeks (1 week veg and 10 week flower) I'm always interested in new lighting I wonder how these compare for a home user rather than commercial grower.
Can either of these light be hung vertically or are they reflector only style LEP lamps?
36-40"...Strain and Environment dependent and if both are accepting to it MAYBE 30". I've seen Sour Diesel tops disintegrate at 30 inches.Whats the minimum distance from plant on the Gavitas ?
I run 2 e pap and 4 gravitas and there is no comparison gravitas are more efficient substantially even if spaced perfectly to epap spacing gravitas do better
It's recommended to swap bulb and reflector every year, this is the most logical in an efficient commercial application.the e-pap and the Gavita use the same drivers right? you said they were different but they are from the same company IMO. Also mentioned was that ePAP was made for commercial operations, Gavita fixtures are also right? What about the PL light fixtures that also came out with some of the first DE lamps? They also have two reflectors so I can get whatever pattern is needed in the space. As far as what one runs cooler? the lamp operates at 750C efficiently, so cooler running is not always a good thing in the DE lamps, That is why air cooling is a bad idea. Doesn't the reflector on the gavita only last 1-2 years?

Same drivers? Ballast? I highly doubt it, but do not know for sure. This is something I can look into.
I do agree the DE, to run efficiently, cannot be air-cooled. Let's be honest though, why would it matter which fixture ran hotter, in a commercial application you should be over-sizing your A/Cs. There is no way either of them put out more then 4,000BTUs, the Nano DE puts out exactly 3700 BTU.
Gavita is certainly a commercial fixture.
Each of the DE reflectors serves a purpose. The E-Pap style reflector will work much better when emphasizing 'tops', where the Gavita will perform better when utilizing it's penetrating ability and developing lower flower sites.
The new PL fixture isn't something I've worked with much because, as a business, we can't profit from these. This is because PL lighting will sell direct. It's a shame they've chosen that route because they miss out on valuable marketing. I will still put it through our testing but I don't see it making a dramatic difference.

There is NO way that PL is only emitting 2400 BTUs.The comment on temperature was brought up by your video, I am just commenting on it because you said one ran cooler. Pl does not sell direct in the MJ market, not sure where your information comes from but I can show you sites where Gavita sells direct if you want to dispute that fact. The reason I mentioned Gavita is commercial also is your video seems to say PL is commercial so it isn't any good. From what I know the PL puts out around 2400 BTU so why is GAvita so high? How did you come up with your numbers? Both fixtures are decent fixtures. It comes down to service, knowledge and the reflector mostly.
I'm the same way.. Love the blockbuster!To clarify my response from above in my grow room it just doesn't penetrate near as much as the gavita and it's not the bulb or ballast I think they are both great just for my application I don't like the light throw it puts out. I was always more into the block busters than the xl hoods back in what seems to be the Stone Age now lol
Video aside, I can assure you we arn't outfitting 4x4 operations... Largest one, this week, is 150,000 sq ft. We set up our clients with exactly the right fixture. And to be clear I don't work in commercial, I run the R&D department in my company. If you would like to continue this discussion please do so in the other thread, pertaining to lighting.
