About 2000 lumens per 23 watt 2-foot bulb. I have 8 bulbs total for 16000 lumens of light with a mixed spectrum of 4 @ 6500k and 4 @ 3000k.looks nice for only a couple hundred watts. what kind of lumens do you get from those?
I've had good success with the T5's. High output, low heat and low electric use. My grow space is too small for the 400 HPS I have; burned too many attempts. Too hot.
Good luck. I grow indoor/homemade hydro setup by the way.
