The Tikka XP2 is a decent headlamp. I would recommend checking out some lights that have real regulation (keep brightness until the bitter end of the battery)
I love the ZebraLight H51 (bit pricy at $69). This is a 1.2oz (3.5oz with battery and headband) headlamp that runs on a single AA batteries. It has 6 light levels from with good quality regulation (lumens/time: 0.2/19 days, 2.5/3 days, 8/39h , 30/12h, 100/2h, 200/55min) The beam has a hot spot with enough throw for way finding and enough spill to be useful for around the camp. If you really don't care about night hiking, the H50 is $49 with the best area / flood I have seen.
It's a bit funky, but the iTP H01 is a good value a $29 runs on a single AAA battery. Output: 1.5lumens / 50 hours, 18l / 4h, 80/1h. Weight: battery + 22.8g light, 50.8g light+ headstrap
