how to extend the life of XTAR D30 4000 dive light

How to extend the life of XTAR D30 4000 dive light? A very important action is to clean the waterproof o-ring and add lubricating oil after diving.

My new d30 4000 leaked and got destroyed in the first use. Could it be defective? I am using many Xtar torches but never had any issue

My XTAR D30 4000 leaked last week and that was my 4th time using it and it was only 4 meter deep. Are there anyway to fix water damaged?

Sorry for the trouble. Please contact [e-mail] for more details (photos or videos may be needed). Or you can go to the warranty process (link: www.xtar.cc/intro/Warranty-process-16.html ).

This thing has general problems. There is no leading edge on the bottom plug, means it push out and damage the o ring. A lather can make it, but it is not in the user manual. The battery space is too small, cause pcb damage and it become unreliable. I can fix it with my milling machine, but it is not in the user manual, too. It must evolve....
