BRUCE P No I do not have a backup bulb. The bulb is soldered into the lighting unit which includes capacitors, and other electrical components.
HENRY L Thanks for your answer to all of the staff who addressed my query. Bruce I know the Xenon strobe 200 does not use a bulb per se. Do you carry the lighting units for this item.doing deep dives in the far east it is wise to carry redundent systems for most equipment..I think I found a replacement unit a while ago (years actually) and have used it until its life was exausted. I ask because I think I paid more for the lighting unit than what you sell the whole unit for. Hank Lynch. PS I have never had this light flood and use it at depths of 120 to 165 feet in wrecks to lead us back to the entry point
