Sofirn/Keychain

Sofirn SE1

The cheaper of Sofirn's two coin lights swaps the Pro's high-CRI white and RGB colours for a low-CRI cool-white emitter and a 395 nm UV LED, keeping the RGB signal ring. Three hundred lumens from a 140 mAh built-in cell lasts 42 minutes on high before it needs the USB-C port. IPX5 covers rain and splashes, not a dunk, and at 1,454 cd the beam is a short-range wash rather than anything that reaches.

Beam profile

Balanced, about 29° wide. A usable hotspot with enough spill to see around it.

Estimated from 300 lm ÷ 1,454 cd — how this works
