Just as an interjection, you can grow plenty of fine bud with cfls.
But we're talking about the screw in led bulbs so i will counter
@buzzyman32 that the off the shelf led bulbs are a great source for lighting for medium to small sized grows, and efficiency wise they are actually pretty decent, and on other forums there are plenty of people getting great results from screw in led bulbs only.
As photons of energy are just that, so as long as whatever source we decide on can provide that to our plants in a somewhat efficient means then we have the ability to grow great plants, so they should definitely not be discounted, and yes as
@archie gemmill said i am currently running three 8w dismantled ones in a 5 gal bucket grow, so we will get to see what they can do so long as my plant behaves.
But the old adage rings true in don't knock it till you try it, as these bulbs are definitely worth while, just pop the domes off and your in business.
Honestly ill probably start up a thread shortly here on AFN as screw in leds are a perfectly viable option and they definitely have their place, they just aren't represented on these forums, but i can already envision the nay sayers as i don't grow big because i don't need/want too, so its gonna be hard to convince people they are a viable option without doing bigger plants so ill be expecting some push pack for that.
But
@steve bossie go for it
