Anyone ever use CFL Flood Lights?

I was over at 1000bulbs looking at what kind of CFLs I wanted to use inside my growbox and I saw these floodlights and I was wondering if anyone had used them before?

They have a built in reflector, so they might just be perfect, but it depends on if they flood, or if a spot effect forms being so close to the plants.

Here are the lights http://www.1000bulbs.com/23-Watt-P38-Compact-Fluorescent-Light-Bulbs/37838/

I was thinking of covering the ceiling of the grow box (rectangular) in these, 2 outer rows of 8 and 4 along the middle. (Micro SOG)

Like this

man id just get the 23 watt cfls they get the most lumens per watt anyways...

The floods are 1200 lumens and standard 23W cfls are 1600 lumens. But the floods are directed, where as the standard cfls just throw light in every direction.

Hard decision! That is why I wanted to see if anyone else had tried them.
