Light source question...

[time_to_shine]

I was recently installing security cameras at a body shop when I notice they were using a couple of DeWalt DC020 for a light source.








I know many use this type:



My question is Fluorescent Worklight like the DC020 or Halogen Work Light ?

I was able to use the DC020 to assist installing the cameras and noticed it didn't get hot like the hologen, was bright and I was able to turn it off and on with no delays. Wondering if any one else used these style lights and there thoughts on them.
Price wise you can pick up one for about $90 replacement bulb for $25 and runs on Dewalt battery packs (12v or18v) or cord.
Thanks for your input!
