I might change my mind if I could get a nice diffuser for my M44 though since the boost-driven Nichia’s are more appealing to me. With a spare set of cells and charger that can take USB-C input that I’d be packing for other reasons anyways, it wouldn’t be a a real inconvenience either.
While the fridge itself may not be humid, once you take it out, you will be someplace that likely is humid. And that’s where the fun begins… and by “fun” I mean “condensation”.
