    What are the best LEDs money can buy, and the best value?

    Agree with what cobkits said. You could easily get 200 lumens per watt with some Vero 29s. However I think Citizen 1212s are good enough at around 160 Lumen per watt. Last time I checked Gavitas HPS gave out around 135 Lumens per watt and throw out a ton of infrared heat in the grow...

    New CREE COB finally launched

    Does anybody know yet the actual % difference from these and the old comparable CREE's? Im guessing the die increase means we will have to up/down-grade slightly with the past chips to match better for comparison. As it stands it still looks more favourable to go with Citi's tbh...

    Input needed for experiment comparing COB LED to HPS DE

    If you don't have the capital/equipment to run the same spectrum for hps & led in veg, then the same spectrum for hps & led in flower, you could still do your test full LED for veg/flower, and full HPS for veg/flower - maybe it wont be 100% ideal, but I guess the results would still be valuable...

    New Timber Grow Light Fixtures

    Didnt notice the link. However, I didnt know fatty was just a name for the fixture, I thought it maybe a slang word for a type of vero 29 led.

    Can I leave my plants in dark for 48 hours?

    I am at the end of veg but yet to enter flowering. A very disadvantageous scenario has occured and I must leave my plants without light. Are there any significant problems that can arise from this?

    Thermodynamics states that Energy cannot be created or destroyed within a system, we could call this system our universe or for your objective the system being a sealed room with 250w of HPS, and 250W of COBS. The part your missing is that when the objects under your HPS or COB absorb the...

    I understand your view but its slightly wrong, it is the case that even if cobs got to 99% efficiency - say 49.5W into useable light - heat will still come. The difference being HPS waste much on Direct Heat from loss, COBS have less Direct Heat from loss. You could say then whats the point of...

    Spectrum King

    Having many light sources(cobs) over a spread area than one centered light(spectrumking/hps) giving uneven light to all plants is better?

    Why do some LED lights cost $800+ without being 8 times bigger?

    To answer your question, most prebuilt LED lights are priced at over double the cost of parts. If you really want a quality product, build it yourself and a light retailing at $700 will probably cost you around $300.

    This is another obvious false comment. Many people are getting 1.5Gpw with cobs, are you saying your getting 3Gpw with chilled? Its clear your just frustrated because you want people to stop using cobs and all go and buy chilleds

    But the heat generated from them after all conversions is the same. If you put a cree/citi/vero @ 50W in a sealed room and measured the temps they should record all equal. - even though some offer more L/pw

    Your quoting Timber who sells highly-priced COBS Yet before that you post Its clear you are not being honest here, And I can understand why you would want to block me, I shed light(no pun intended) on your attempts to defame DIY / COB Technology. Again I have no issues with either...

    Its you thats doing the "picking" and trying to talk down on people. If you want to pay $749 for a 200W light when you can build an equivilant yourself with cobs providing better uniformity for $350 then thats your own waste of hard-earned money. Also what a useless post saying COBS cause...

    CREE cobs are not $40, again your using prices going back 3 years ago in a poor attempt to save face because you were called out on the false information you posted. Its better you stop digging yourself a deeper hole and admit you overpriced. Later tonight I will get some prices for latest end...
