Bro, all I can say is that it takes a lot for me to be impressed and I'm impressed. Haven't seen anything flower as fast and obtain the density/weight these things put out. Will have to wait to try the 4200k in veg until I build a bigger veg area.damn these lights are that good huh?
abso-fuckin-lutely!damn these lights are that good huh?
Many of the same points I've been posting in my thread, no popcorn (=great penetration), buds dense as they can be, matching 600 hps yield/coverage with 315w, no heat... I was specially blown away because I did a bunch of testing of low-end LED's which produced next to nothing in comparison.
did you try the 4K in flowering? It worked great for me.
No not yet, the spectrums are close and both will flower, would need to do a side by side with same strain clones to see if there's any significant difference. Interesting thing on the 4200k is that advacetech recommends that colour/spectrum but has no data to provide in comparison to the 3100k. Don't know if I'll be able to do that side by side as I'm pretty well done testing mode with CMH, the 3100k has proven itself so I'm good with that. I have a second fixture firing up shortly and have 4200K bulb available bout nothing to grow out that would give me a solid comparison/control, so I'll be using the 3100k.
Advance tech only uses the MOGUL bulb, right?
They (advanced) provide a mogul socket adapter, the lamp itself is a T12 and comes in unprotected (not recommended) and protected. It also comes in 3100k and 4200k, 210w and 315w, model number is 930, that's it for the Elite Agro. They have some others in their Allstart line but they're not the same specs, nor tried them so can't comment on how they'd compare. I'd stick to the Elite Agro's. Attaching the best references I've found for these bulbs, one is from Ceramatek but lists both the 4200/3100's.
If Advanced Tech is offering the agro that is a big change! He used to call the Agro the 'dildo lamp', and dislikes them greatly compared to the mogul version, last time I talked to him 3 months ago.
Toms a great guy. Will talk your ear off if you let him. Knows a hella alot.
Weird, they've been on there for a while, some guys here have been buying them. This link goes directly to that page. The default link is the 315w/4200k. But under the first pic with the ballast he mentions availability of the 3100k. I use the Sun System that comes with the 3100k by default. So far nothing to complain about these bulbs, for 315w they can pull a lot of weight.
Ya, like I said, he says on that link "We sell all the lamps but In horticulture after real testing we like the 210 and 315 in 4K Mogul Format."
