Chip On Board, lots of dinky LEDs over a bigger area rather than one big one, I reckon they're better for "be seen' lights, with a nice big visible area, so especially good at the rear.
Cobbers are pricey but the + is decent enough and really handy, clips onto stuff or magnetically into little holder, USB plug built in so no need to remember charger, decent pulse mode.
