I have been using the Energizer brand headlamps. Sufficient for my needs. I use it at wildland fires on the job, traversing various terrain in the dark is a expeirence. I use the Trailfinder with 7LED. It uses 3AAA batteries. Quite reasonable and would be a great tool on the night stand for when the power goes out. My lamp is attached to a hardhat, but one could easilly cinch it down on the scalp. I am on my second one, picked both up at Walmart. the first lamp is non operational due to battery acid leaking on it. I had it for 2-3years. It was fine last I checked, but recently in a pre check it was non op so I looked to change the batteries, but they were all corroded. Cahnging the batteries didn't fix the problem, so I just bought another for $20-25 at Walmart. I think when choosing equipment that requires batteries, a key point is type of batteries. Surefire style batteries imo are less desirable as they are harder to locate.
