Review: Thrunite TH30, the most powerful 18650 right-angle headlamp

The Thrunite TH30 is a right-angle flashlight/headlamp using a single 18650 battery and a Cree XHP70.2 emitter to make 3350 lumens. It has the highest output of any light in this form factor as of this writing. As a result, the size and weight are higher than average, but manageable for those who value output. It features USB charging and includes a suitable high-drain 18650 battery.

Review: Fenix HM50R, a compact angle headlamp that adjusts its brightness whether you like it or not

The Fenix HM50R is a small right-angle flashlight/headlamp using an included 16340 rechargeable battery and USB charging, or disposable CR123A battery. The HM50R features an intentional slow rampdown of its brightness during use designed to prolong runtime despite having hardware capable of sustaining full brightness. There is no way to turn this feature off. It seems like the HM50R is designed for inattentive users, or to compete with low-quality headlamps that advertise absurdly unrealistic runtimes.
