Lighting 90cri vs 80cri

[Slater]

Ok guys I can get 3000k 90cri 72v or 3500k 36v,
Is it just a different driver but will all work the same???

if your driver has forward voltage of lets say 200v then you would be able to run 5 x 36v cobs over just 2 x72v cobs (depending on the wattage). Its the forward voltage if the driver that tell you how many cobs it can and the wattage. I run 5 x 36v at 3500k and my tent is rocking. Here's a link to my build

Ok, I'm currently running 3 36v 3000k on a 120-1400 so if I go 3000k 72v on a 120-700 will be exactly the same yes??
Thanks

Can I run 3 72v on a 185-700? At 50w they don't have the 120 700 in stock or the 36v now either

I think you can only run 2x72v on a 185-700... For 3x72 (216) you would need a 220-700

So if I currently run 3 36v on a 1400ma I should be able to run 3 72v on a 700? No?

The 700 or 1400 dosent really matter... IT is what Come before that...185-1400 dividere the 185 with v....185/72=2 and some so can run 2 72v cobs at 1400ma. Or with 36v...185/36=5 and some so 5x36v cobs at 1400ma... The drivers Seem to fit 36v and 50v much Better than 72v

I could only get the 72v so have 3 of them coming and will order the 120-700a.
Then running that bar with the 36v we will see, from what iv seen in the data sheet it should be exactly the same

I run 150w bars 50w each cob

1812/1212....doesn't really matter how many diodes are in the chip, this is about cri... But i think u are right.. The latest update says 90cri has bigger flowers and will definitely be coming down sooner.. Final weights to come..
And the 120-700ma will work.. Could be a volt or 2 short if your dimming.. Not a big deal..

Could you please try again? I bought 1212 3500k 90cri v6 because of the results here. Can anyone pm the source to me?

I ordered same leds ,Now my question is they will be together with 3070 3500k cree but 80 cri..
Should I rotate my girls?? Or better not?
