Led Grow Bulbs? - Micro Pc Grow

[MrMiggy]

hey what's up 420Mag, i have a pc grow box with 4x23w cfl bulbs at the moment, but i am looking into swapping them out for some led bulbs. Do you guys think these will be any good? E27 15W Red Blue 5X 3W Hydroponic LED Grow Light Bulb Lamp Flower VEG Spotlight | eBay

I saw a journal where someone harvested a decent amount from just 22w of leds. Any input on this would be great.
Chears!
