I was recently doing a bunch of wiring and using zebralight headlamps (I have two that are pretty old---don't recall the models) and found that their lifespan was annoyingly short when run at a satisfactory brightness. They also got really hot. Recently I've seen a bunch of ads for a COB headlamp with a large strip of COB LEDs across the front, which seems like an interesting idea. The product was "flexbeam" and the horrible marketing suggests that the product is probably terrible. But it made me wonder if there is a good product in this category. There are a bunch of cheap products like this floating around. I use AA/AAA eneloops for everything and don't want to branch out into Lithium Ion, so I'm wondering if anybody has any suggestions about alternatives, ideally with good CRI.
