Does the diy cob is safe to use ? i currently plan to try the marshydro cob 100w, have you guys heard of this light? or i will choose to diy my own light?

- With CREE CXB 3590 COB, Brighter, Cooler, Higher PPFD
- IP65, Water-Proof
- QUIET to USE, Even in the BEDROOM
- Great Choice for Small Growers!
That Mars light seems to be one of their better lights, but they decided to run COB's and secondary deepreds more on the hard side. Probably 2,0μmol/J efficiency and you'll need one light each 3ft² because it's only 100w. Ahh, forget the 2g/w claims, thats BS.
I would rather built something myself.
Four Samsung 2ft. F-strips at 1050mA would be 100w too, but at least 2,4μmol/J.
With four latest generation COB's(like Luminous CXM22, 52v COB) at 525mA you can get the same efficiency.
With COB's you need small heatsinks and fans or passive pin fin heatsinks. With strips you only need an alu sheet/flashing to mount the strips on.
With Bridgelux EBgen2. strips you even do not need the latter, they can run completely passive with up-to 1050mA. Only a frame is needed, no need to mention that such a build weights almost nothing and does not need a strong hanging kit.
Can I ask how big your area/tent is?
