i bought the chinese 100 watt chips to try my first build.it was easy.i have now built 12 4 cob cree cxb 3590 lights running a little over 210 watts at the wall.the cxb lights put out an easy double the light compared to the chinese 100 watt chips with the same 50 watt driver.Im currently running 2x 185 HLG C1400A's on 4x 6500K, 4x 3500K
On ebay 100w chips
the first 4 lights i built used the same 50 watt drivers that i built my chinese light with.
now the last 8 have the same meanwell 1400 drivers you are using.
either cxb light with which ever driver i used look about the same but the chinese cobs pale compared to them.the price on the cxb's have dropped or try vero 29 if you want a slightly cheaper good chip.
happy growing!
