if power consumption is an issue, maybe one (or more) of the luxeon units used in flashlight conversions would work; else if you want area light and can afford a couple of watthours to get it, halogen would be better. of course, again, halogen would prefer to be on for a decent time per start. . . but they do better in motion sensor lights than CFLs do. It's not a case of 'Save the planet,' it's a case of 'Save the humans.'
