Well I guess 32,000. Blue bulbs are rated 6400 and red at 3000. I'm Growing an old affy strain that I bummed off a vetran grower. I'm tempted to slip the other 4 red bulbs in but that would drop my lumens some, and my girls really do look good so i'ma leave it. I been thru overheating problems. light leakage problems, bugs, manual light timer failed, (digital now) Getting it dialed in is fun tho,, good luck man!
