Fenix PD36R Pro

It ranks #6 (C tier) on our consolidated flashlights board, drawn from 8 independent outlets.

Higher price. Bulkier design. Limited battery life.

Someone who wants a very bright, robustly built light backed by a long warranty and does not mind the size. It sits in C tier at rank 6 on our flashlights board. The research credits very bright output, a robust build and an extended warranty, but marks it down for a higher price, a bulkier design and limited battery life. If you want brightness and build without the bulk or the runtime penalty, the ThruNite Archer 2A C or the Olight Arkfeld Ultra in S tier is the better buy.

The ThruNite Archer 2A C, the rank 1 pick in S tier, which matches the strong brightness and solid build and adds long battery life, the thing the Fenix PD36R Pro lacks. If you want to stay with Fenix, the Fenix TK20R V2.0 in C tier is credited with excellent battery life and a low failure rate, which fixes the main con here.

Not as long as its size suggests. The research records limited battery life as a con, which is the usual price of a very bright output in a light that is tuned for brightness over runtime. Use the lower modes for most tasks and the runtime improves a great deal, since the highest mode on any light drains the cell fastest and steps down for heat anyway.

For pocket carry, the research thinks so: a bulkier design is one of its three recorded cons. It is better suited to a belt holster, a bag or a vehicle than a trouser pocket. If size matters, the ThruNite Archer 2A C and the Olight Arkfeld Ultra in S tier both deliver strong output in a smaller body.

It is its strongest selling point after brightness. The research credits an extended warranty, and on a board where several lights show failures after 18 months, a long warranty turns a possible failure into a replacement rather than a loss. Keep the receipt and register the light if the maker asks, since warranty claims usually need proof of purchase date.
