How they stack up

BioLite Range 500

The BioLite Range 500 offers faster charging than the Knog Bandicoot 250, which charges in 30 minutes versus 2.1 oz's 2.5 hours, and provides more consistent runtime at 200 hours on low. However, it's not as bright as the Fenix HM50R v2, which delivers 700 lumens, and lacks the IP68 waterproofing of the Fenix.

Nitecore NU25 400 UL

Against the Silva Trail Runner Free H it is cheaper and lighter, but it gives up the Silva's hybrid battery system and its simpler brightness switching. Among ultralight rechargeable lamps its strength is feature count per gram rather than raw output.
