Thanks for the math.that= 800 lumens x 12 = 9600 lumens/$25+ 12 sockets@$24=$49, 90 lm/watt, 5.1 cent per lumen
feit = 1500 lumens x 10 -15000 lumens/ $50+10 sockets@20 =$70, 110 lm/watt, 4.6 cents/lumen and 20% cheaper to run
$50 a bulb?Thanks for the math.
Wish I could find them in 2700k for the price you paid.
Says the brand is "FDW"?Checking these out on ebay.
Not much info though.
9 watts 800 lumens.
$25 for a 12 pack.

I checked their website but only found 10 watt A19 bulbs.Says the brand is "FDW"?
This why CFL need a good reflector.Found some Philips 60 watt "daylight" led's on sale at the homo depot today for $10.00 a four pack.
For amusement and science I tried to snap the top of one but ended up taking my dremel to it.
Wish I would have left a little more intact.
Downloaded a Lux meter for the phone and compared results.
Remember - this was very scientifically done.

Side by side bulbs.
Took a seedling pot and flipped it under each light to rest the phone for the test.

Good point, no reflectors or hood in the grow room and the way led's lay flat on the board.This why CFL need a good reflector.
The LED shines in a 120 degree cone while the CFL radiates light in every direction.
So you get these very low LUX readings.
Results would be closer with a reflector, LED would still win out though.
100 watts would be nice as well.
The FEIT brand is the best that you found. I found em online. 10 for $50.1600 lumen 'Great Value' 15W warm white at walmart for just under $9
