@Chanly83 yeah.... sometimes I feel like a shill for Xtar. But, I have no connection other than being a satisfied customer. Well, that and somewhat obsessive about finding "good deals" and sharing said deals with other people.
Also, just FYI, the Xtar D26 works great with an Oxycheq Raider light sock (the bigger one they sell).
Cave Adventurers - Light Parts and Accessories - Marianna, Florida USA - Never Undersold!
It is very tight around the light, so I have never been concerned that it might slip out by accident. (but I still clip the light's bolt snap to the light sock's bungee that goes around my wrist)
The "universal" light sock that Oxycheq and some others sell really sucks. I would happily give mine away to someone who wanted it. As long as I don't have to put any effort into it, like packing it or mailing it. It's not worth that...
