yea i think it will be about 200 watts with 10 vero 18s..2 x 4 is 8 square feet so at 25 it will equal 200 watts

Ty for that, maybe I will go with vero considering I'm looking for just lumen output for bonsai to thrive. Do you think 3 or 4 vero 18 can be passively cooled on 18 inch 3.5 heatsink. If I don't need to add fans that would be great.

Ty bicit so if I can passively cool those without the fans then that's as quietest as I can get. Are you saying by passively cooled at 25 c which I see charts with those numbers. Than I should do that. As led drivers since I can't do them all on one driver is there a good one that can do 3 at...

Ty so much supra you are the god of led building. Also Ty church haze for your great input as well. Can you recommend a quiet 80 or 92 mm fan I'm looking for less noise really. Supra do you think I'm just better off with 6 3000k for overall veg n flower for peppers. Considering I'm not looking...

Anyone else on the other questions?

Which meanwell drivers can do 2 or 3 cree at 1050. I was on the website not surfeit that will cost sufficient as it may be cheaper to just get 6 I think.

Hello everyone after looking around these boards constantly i have been trying to figure out a few things. First off i wanna use 6 cxa3070 for my build which is 2 by 4 feet. Here is what im trying to do question wise. 1. 3 cxa3070 at 3000k and 3 at 5000k would that give me a good spectrum of...

Sorry one more question is the 3000k more or less full spectrum I'm actually doing bonsai peppers ,so I think I need more veg per say then flower.

Ty so much for the spreadsheet and explanation. So since he runs at 700 his actual wattage would be 26 watts correct, also I'm assuming that would reduce the amount of lumens as we'll. also do the Crees need to be spaced a certain amount of inches apart as I see the 3w led needs to be placed...

Hello all. First off merry Christmas to all.im interested in building a grow light for my plants, I'm just a tad confused about a few things. As I don't want to go over 250 watts I understand even if a led is rated let's say 32 watts you want to run them at a lower wattage is that correct? Now...
