Anyone used the 2d CFLs?

I've ordered 2 to try for the tops of the plants during flower, and am going to use regular CFL's on the side. Theyre about 8-11$s online for a 39watt bulb, Anyone else have experience with them? I havn't found any daylight ones yet, but from what i've read it seems like theyd be good for the short bushy plants cfls make.

I'm a little worried about the no coiling of the light though, am I just going to end up with some lamp bulbs?

i was going to use these but i have no idea how to wire themor anything, im sure they would work though

The ones I ordered came with a normal bulb base that you can screw into a regular socket, and the CFL "slides" into the top.

ala

Seems like it would give even coverage from up above. About how big is it? [LxW]

Not sure, hasn't arrived yet. The package size is 12.6" x 9.6", so im thinking 7x7 or so.

hmmm... interesting... I would put those at the top with some sort of homemade reflector, and with normal CFLs on the sides or additional lighting.

this looks good
thx for the idea
