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

Thanks for the math.
Wish I could find them in 2700k for the price you paid.

I checked their website but only found 10 watt A19 bulbs.
Was looking for number of diodes and other specs.
Might just order some to take apart and or use around the house and a few in the flower room.

All CFL's now in Y connectors. Not sure the Y connectors are a good idea with directional LED's either.

i wonder how these chips would do mounted on a real heatsink with a better driver. they are marked 96V, 96V drivers dont seem too common
 
Just moving the chips to a heatsink and the drivers out of the grow area is a huge improvement. You can customize the spread easier, cool the chips easier for better performance, remove driver heat, and make them easier to wire.

If the chips remove easily it only takes the extension of two wires. The positive and negative wires will need soldered to the lengthened wires. You will probably need to drill holes for the chips unless you use thermal adhesive.

You can even skip buying lamp sockets if you pop the socket off the bulb and wire it directly to a cord.

Its a cheap source for components if you don't mind some tinkering
 
if you had the know how, you could do what grouch said and make some really kick-ass vertical lighting. With the right setup you could grow some monsters without worrying about penetration problems and could even just turn on layers of chips as needed as the plant grows.
 
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. o_O

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

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.

Good point, no reflectors or hood in the grow room and the way led's lay flat on the board.

Good for my little grow room though.
Gonna replace 2 cfl's with 2 led's for a test. see how they grow.
