I'm considering upgrading to a smaller, lighter, brighter can light, something that I can also pack for tropical travel. If I did this I'd sell my trusty Salvo 10W variable-focus can light. An easy local sale could make the difference for me, so if you might be interested please PM me.
The light comes with a battery pack and charger. It works fine and has never given me ANY problems... but I do have to disclose that it is on its first bulb and they don't last forever. This bulb has been on about 100 dives so it should have a lot of life left.
