I don't have a lot of time to write something up, but I've had a lot of headlamps and for *task* lighting (it has a 'flood' beam), you can't beat the Zebralight H30.

Very small, ultra rugged, waterpoof and versatile mounting options.

Zebralight H30 Review

In general I don't find the Petzl products compelling, *but* the e+LITE is a nice *tiny* light and I have several.

Keep in mind that with the little coin cell batteries this isn't a light you are going to want to use for long duration use.

BTW, for old style lights, the Princeton Tec Yukon series lights aren't bad. PT seems to take waterproofing a lot more serious than Petzl. The e+LITE is an exception and appears to have good waterproofing.
