Lost my HID light head (damn E/O connectors and ocean diving... I knew I should've stayed in the caves) and used that opportunity to replace it with an LED light head. No more breaking bulbs and stuff.

I still have a new and unused field repair kit for the (older) Halcyon 18W HID
(details here: http://extreme-exposure.com/?q=node/1748). Contains HID bulb, test tube, o-rings, switch boot. With the exception of the canister o-ring (which is specific to the 9Ah canister), this will work for all Halcyon 18W HIDs.

MSRP $250. Asking $150 (free shipping in the US).

P.S. If you want to look for the light head, it should sit in approx. 130 ft depth a few 100 ft NW of the Spiegel Grove buoy #6 (port superstructure)... Finders keepers - I only ask that you send me the scooter thumb loop that I put on.
