What other lamps have you analyzed? Any chance we could see some of the graphs?
Where does Gavita currently stand on incorporating the Philips 860w Allstart tech or similar into their product range?

whats this about resin production? I am a couple weeks into flower with the GE 400w cmh bulb that comes with the HTG setup. I am seeing very little if any trichomes. All the plants are news to me, and autos. One 'critical' seems to be putting a little on today.
The growth rate with this setup is amazing. Had it for a while, but never used it till now.
I am going to swap it out w/ a 1000w hps right now. I need better penetration/ canopy coverage, as things got out of hand and are borderline too much for the 400 anyhow.
Anyone have experience w/ the htg/GE bulb? I plan to keep using it now for the mamas and clones in the new room. It definitely kicks some butt in the veg--clones do well, great on veggies too, and peyote and T. bridgesii LOVE it. Also promotes INCREDIBLE flushes for mushrooms. Better than Ive had in 20 yrs.

The GE 400w that is "made exclusively for htg supply" appears to be a little better lamp on paper, no personal experience with it yet, however for my veg I will be switching to these from the philips 4k. I agree with what some have said that right out of the box a hortilux blue is slightly better for veg, but within 90 days the cmh is going to grossly outperform for the rest of the lamps' lives...
Interesting. I've read nothing but bad reviews about the GE lamp that comes with HTG package. I'm not concerned with Hortilux bulbs, I know CMH bulbs are superior. What I'm wondering is if the Phillips MasterColor 400w bulb is still considered one of the best CMH lamps available. They have been discontinued and I want to know if it's a worthy investment to stock up on these bulbs while they are still available. I don't want to blow a wad of cash on these bulbs if there are better ones available. I ask because I've seen alot of discussion in this thread about some Argo Elite lamps?
I haven't used the 400w Mastercolor, but I have been using the 315w Elite series. I think that the 315w gear is currently the top of the heap from a variety of standpoints (lumens/watt, spectrum, lumen maintenance, overall longevity), but they have entirely different equipment requirements than the other CMH lamps. They cannot be used with HPS ballasts, and require their own specific electronic ballasts which are pretty pricey at this point.
Ahh yes, alright. Thank you. I can't afford that ballast right now. Looks like I'll be going with the 400w MasterColor and a good ol' $100 magnetic ballast.
I've been going back and reading thru this thread and I have a question. Should I be getting vertical lamps and using them in horizontal reflectors? Not really understanding that discussion.

Not sure what discussion you are referring to, but only "universal" lamps should be used in either orientation. Vertical lamps are to be used vertically and horizontal in the horizontal plane. You can radically shorten the lamp life by running it in the wrong orientation.
Reading about the 400 W Phillips Mastercolor I got the impression that the vertical bulb is designed to be in a fixture with reflector casting light in a downward direction. But it was a bit confusing to me. Is my interpretation right here? If so then it wouldn't be that useful as a bare bulb in a vertical grow.

in the middle of the room you need less luminaires, the walls give about 85% reflection, so you are losing about 15% light there. Also the walls reflect light with a lambertian radiation pattern so not all the light is directed down.
At 900 mm distance between lamps and plant the realised uniformity is
in this room the light can be dimmed by switching off fixtures in 7 steps, (in total there are 49 luminaires)
in the future these d-papillon fixtures will be soft-dimmable.
we check if they comply with what the manufacturer has specified and we test new types. If they don't comply we can't sell them to our customers. The manufacturers (at least the serious ones) all publish their spectral power distribution diagrams in their technical documentation. You can download the diagrams from Philips, GE, Osram, Sylvania etc. from their websites.
We have no stand on the 860 allstart, as we have no plans at all to use it.

Why isn't it even being considered whazzup?

The 860 allstart is about 9% less efficient out of the box vs 315w agro (initial lumens), the 860 is strong in the middle of the spectrum which could have further inflated it's lumen figures.. wouldn't think it would challenge hps, except those who desire a one-bulb-&- done setup where quality is more important than yield... No interest in this lamp here, has a good spectrum, butI'd wait to upgrade technology philips is moving quickly and this lamp was a stepping stone,, not to mention it runs on 1kw magnetic ballast if I'm not mistaken.. just my 2c

Understood. Just curious is all as to if there's a reason and if it is something which would also affect my opinion of its use
This has me confused also. there's much discussion in this thread about using vertical lamps in horizontal reflectors. If you ask me, thread should not be allowed to get this large. Over 300 pages of arguing and very little actual information.
