Why don’t the H52 fans take the logical step up to the larger 18650 battery?
Not answering for everyone here, but for me, I did not want a headlamp with such a proprietary battery. With the H51 (or the H52’s now available) I can use AA, whether that is alkaline, lithiums (my choice) or rechargeable’s. I initially bought some Eneloops, however, decided to go with the Lithiums because they are lighter, last longer, and perform better in the cold. Also, if need be, finding an AA battery would be much easier than finding an 18650 battery, heck, good chance someone else would even have an AA to loan me while on the trail. So the 18650 battery was the illogical choice for me.
I have never had to change a battery out in my H51 while in the field. Granted most of my hikes are only 3 days, with my longest being 7 days, so there is that. However, I rarely leave out with a brand new battery, and it works great, for a long time. I will use the same battery while out hiking (at camp and sometimes early morning or early evening hiking) as well as around the house. Trust me, the lithium batteries last a long time…
As for brightness, the H51 is only 200 lumens on it’s highest setting, but wow, that is bright. I have used it to throw a bear line on some dark nights, and it could have been turned on the lower high setting (100 lumens) and still been fine. While hiking one of the medium levels is all I need, and sometimes have even used the high low setting. Then of course the lowest setting is great for reading, or getting organized inside the tent.
And I mentioned weight above, but for my H51, with a lithium battery and my DIY headband (can be seen in my avatar to the left <——) mine comes in at 1.99 oz! That’s a lot of light for such a little bit of weight!
And I completely agree about going with the neutral vs the cool white light… It’s the only thing about my Zebralight that is not perfect… but I love it so much I will wait until I have to swap it for another. They make some great lights, so that may be a while… lol
Edit to add: I used to use a e+Lite, but after having to hike out unexpectedly in the middle of a dark night, I found that the e+Lite was really a poor option. I ended up using a little keychain light that was much better… After that I sold the e+Lite!
