Yeah, I too would get the halogens if you can only have one.
But I sure wouldn't want to have only one type of lighting.
And yeah...an incandescent trouble light costs ~$25 at Lowe's and while I don't find most flashlights all that great for swirl-spotting, everyone should have flashlights around anyhow (no matter what, zero excuses...this can be life-and -death during emergencies).
