I got an UltraFire WF504B for my dad ages ago from DD. I charged up the 18650 battery for it but I noticed it isn’t really putting out much light at all anymore - it is really dim . I tried the battery in my L2P (with Manafont Ultrafire Cree T6 3-Mode drop-in) but it is as bright as anything in there, so it isn’t the battery.
Is there anything else I can try or is it time for a new light? Or perhaps just replacing the drop-in? I’m a bit stumped since it hasn’t seen much use!
Sorry for asking the obvious, but how would you get the switch out of the tailcap and what would you use to clean it? It doesn’t look like it will come out too easily and I can’t find anything on the forum regarding this.
Should be held in with just a threaded ring on the inside(battery side). Unscrew this with sharp needle nose pliers or good strong tweezers by twisting with the points in the 2 ring dimples.
