I've had this light for 6 months now and I use it as my primary for cave diving. It is a great led light however my primary dive buddy has a 21 watt HID light which makes it hard for him to see me sense my light is not the same as his. So i'd like to sell this and get one equivilant of his. This light retails for $799. It comes with a case that it goes in as well as the charger. It has a great mounting sytem on it that makes it easy to mount for back or side mount. Im looking to get $500 for it. If you have any questions or want me make me an offer send me a message. Thanks
