Was working in my attic yesterday. I had on my Energizer headlamp, I don't remember the model, that is great for outdoors. Has great throw for a $20 head lamp. But no flood or spill so it is watch the hot spot at close range. I want something with a wide flood beam at close range. 2xAA would be nice but I don't think it exists. So I am looking at 1xAA. I like that the Fenix HL50 can take a CR123 when extended but the modes are wrong. I am looking for roughly 18-25 low, 50-60 medium and a 100-120 high. The modes don't have to be laid out exactly like that but it is what I have in mind for a guide. I am looking at a Zebralight H502 but I am thoroughly confused by the modes. I plan to run Energizer Ultimate lithium batteries. What would you guys suggest?
