I highly recommend it (or one of the many other Zebralight models).
I agree.
Zebralight have just released their new light, the H502 - it takes a single AA.
WIth a Lithium Primary (such as Energizer Lithium):
- Weight is around 65 grams including battery.
- Maximum is around 300 lumens for an hour (that's not to far off a 60w ceiling globe in your house!)
- Lowest setting of 0.06 lumen (which is enough to read in a tent), will run on the single AA for 2 months continuously (that's 1440 hours!)
- 9 other different levels in between.
Can also be used with alkalines or NiMH rechargeables.
I have the predecessor the H501, and I have never come across a better headlamp for bushwalking (or a multitude of other tasks for that matter).
