Hello and welcome to our community! Is this your first visit?
Northern Diver are now doing the Varilux 3500 Lumen Rechargeable Dive Torch at £99 plus £9 P&P.
Thats for either the old version 13amp plug recharger or the new version USB recharger.
Just for info, here's a brand-new Orca D630 (4000) and an older FinnSub short (3000 lumens, IIRC). The Orca creates a similar beam to the Finn but with more light spread around it. Nice, promises lots of run time and has a USB slot on the top of the battery pack for charging your phone
