Thanks again.. I had two coast s2+ lights, I ordered a 18350 tube, metal tailswitch, magnet, and pocket clip. I blew up the SST40 and gave away the standard one. lol I have two more SST40's (5000 and 6500k) on the way now and an Astrolux S1. The SST40 is the best throw I've personally ever owned in an s2+. If I can fix my blown light with something more floody that would be perfect. Thanks again!
