Lighting Telos 0008 vs COBs oppinions

[Bgddsq]

Hello folks. I try to find a fare comparison between telos0008 and 4 autocobs citizen clu048 1812 but i couldn't find it yet. As you already know the difference of price between this 2 configurations is not significant but i would be really curious wichone is the most efficient and why ? Any oppinion or information would be very welcome.

1.8 umol/s. PPF 449µmol.
I also doubt they cover 3x3 perfectly, because light is rectangular and small.

COBs can do better! Depends how you drive them (efficiency) and what tent you have, but 4 COBs have better coverage.

Thanks mate. Regarding cobs i m looking at bigsmo's one. But i read somewhere cobs doesn t have uv and Ir and this affects the quality of bud is this just a shitty myth ?

4 cobs is about 1.9 amps. The Telos is 5.1 amps.

What does it means in terns of efficiency bro ? I am noob.

Both would be great starter lights, much better than my first try at LED with chinese blurple crap. Spectrum might be a little better with the telos, but the cobs are more versatile and you dont have a single point of failure, which can be important if you dont have a backup light laying around. Also penetration will favor the cobs, with multiple light sources, spread out providing more even coverage.

@thetreeman thanks mate. What do u think , is it very big difference regarding yields between 4 cobs and 6 cobs in a 3 x 3 tent ?

I think 4 would be a great start, unless you are super dialed in, excess photons can cause issues for some growers. Jumping up to 6 autocobs would bring your PPFD to about 720. One thing to consider is this calculator is set to use citi v5 cobs and Sm0 is using v6 I think which are a bit more efficient also, maybe 3%?

Are 2g/w achiveble with bigsmo cobs ?
