I like leds cause of efficiency/efficacy and light spread, I build my lights around these 2 points. I don't know what's the efficiency of V29 at that current but I can say cxm22 are better. If you already know what to get just pull the trigger

Not talking about shitty leds on Amazon like Mars or Vipar. HID or CMH could be good in cold climates to keep ambient temperature at a proper level. If heat is a problem you need to run less watts but you don't want to sacrifice yield, thus leds come into play. Higher efficiency (efficacy) led...

I really doubt any G8 or viparspectra panel is close to a CMH system in terms of efficiency and spectrum.

I bought from export-estonia too, got 5x1212 gen6 90cri and they rock. 90-100w is the total wattage per flowering space, I wouldn't drive the 1212s at more than 50w per cob + you have a short grow space. I wouldn't skip on the Bridgelux eb2 strips (1 or 2 ft). Imho you don't need more than 50w...

oh 42 inch is short Go with strips

What's the problem? Seriously. I red op message 4 times and he never spoke about "cheap chinese lights". Can you evaluate the light you linked? Do you know what you re talking about outside the "led snob"? Are you thinking of buying from export estonia? Imho 1 cob per sqft is enough, you can...

best suggestion is to slow down and research as much as you can http://ledgardener.com/ has many guides you can follow and resources to start with.

with diy and strips you can probably spend 1$/watt

I am looking to supplement my light too but how do you calculate how much of each wavelength do you need?

IF we trust everyone on Alibaba there should be like 5 different HLG suppliers

guys I am still looking for some supplemental strips with reds & blues anyone aware of a seller on alibaba?

by saying "New Driver-Less Technology" do they mean that each cob has a onboard AC-DC conv?
