thats awesome i cant wait to see their results, ive been out of the loop a bit lately

so.. youre just making stuff up then

can we see some pics of your cob grows for comparison?

where did you come up with that number? im not sure which voltage or flux bins the 301bs are but when i pick top flux bin for both 561C and 301b and AZ voltage bin for both i see 4% gain which is about in line with cob gens year over year

grow the type of weed you want to smoke. I'm not a fan of sleepy weed like kush personally, but that may be your thing.

in fact thats the most important factor

its more like $200 a year per DE replaced (in electricity) maybe approaching $250 if you have a major cooling reduction. thats a real number so a 20 light facility would save more like 4-5K in a year

i think by "best" he meant "a larger yield of quality product at a reduced energy input" you can grow hi test weed with cgls, t5s, shittly LEDs, good LEDs, inefficient HPS, efficient HPS, etc thats not really the point of LEDs (though many find it easier to grow good weed as when applied...

theres no "tinkering" with the fundamentals of something as simple as an arc tube. last major advancement was the DE almost a decade ago

including a bunch of white lights as well

also meaningless are they trying to sell you something? if you want to learn how to evaluate a light, you need to gain an understanding of photometric efficiency. If you dont understand what an actual PAR measurement in umols is, or what an efficiency level in umol/J (or even lumens/watt) is...

those are meaningless

which are you talking about? both work. HPS takes more energy to create the same photons though

there are dozens of viperspectra threads and not much good to be said about them

well, LED technology is progressing 5-10% a year HPS is the same as it was in 2011

west coast, will be 2 days to you. best to email me with questions about specific orders :)

per site: "please allow 2 weeks for assembly and shipping on backordered items." yours should be next up tho (2x 120mm right?) this will be the last of the 120mm heatsinks

no links but assuming this is another garbage 200W light for under $200 that they market as being equivalent to 1000W HPS theres several threads like this every week and the answer is always the same: you get what you pay for, but often less than what you paid for

thats apart from the fact that they are coattailing gorilla tents' reputation step right up to preorder their amazing new Razor series, at 130 lm/W. HPS has gotta be getting nervous at this point

yeah i asked them about them last week. what we know: they are electrically same as luminus gen 3 while they have multiphosphor part numbers they dont exist yet, just single phosphor at the current time they are not in normal distro channels im trying to get 100 of each from luminus, thanks...
