I got the Diablo from CRC for £130 (had a 10 off voucher). I ended up sending it back due to it being pretty poor VFM even at that price. Beam pattern is fine if it’s your only light and you want something floody, however I run a bar light and the Diablo was completely lost – could hardly tell if it was off or on, never mind what mode it was in.
The run time was also disappointing on the Diablo, I got about 45mins on full (so didn’t last a 3 hour ride switching between modes)
I ended up with a moon vortex pro for about £34, similar output but a tighter beam, better run times for about a quarter of the price. The vortex also takes spare batteries (£20) that are dead easy to swap so you don’t have to mess about with the exposure piggy back/support cell nonsense.
