If you’re not interested in soldering, you probably have no chance of fixing it. I recommend that you get yourself a soldering iron and learn how to solder, and fix it. But, if that doesn’t appeal to you, the other option is that you could sell it for a much reduced price to somebody here who will be glad to fix it and maybe even upgrade it, while you buy yourself something else.
I have one of these: Yihua 936B soldering station which I bought years ago, and it has been great. I was never able to solder electronics successfully with the cheaper soldering irons that are available. This soldering station is compatible with Hakko brand tips, which are very high quality. But it comes with a nice chisel tip already. I’ve been using mine with no problems for years already.
If you want to salvage it, I have a pill for the S2+, it has a SST-20 4000K emitter and a 8 chip Biscotti driver. No soldering required. Unscrew old one, screw in new one. Tweezers will be successful at that I betcha. Shoot me your address via PM and I can mail it away if you are interested.
Edit: I take that back, it has a Luxeon V2 at 5000K with the above mentioned driver. Sorry I was thinking of another light.
Got your PM by the way. Getting it in the mail today or tomorrow. Only light I had with a SST40 in it was a Jetbeam E20R if I remember correctly. Not sure of the tint on that one but I remember seeing a good amount of green in it. I am pretty sure it was a CW tint so that may explain it.
The Luxeon V2 is quite nice. I haven’t noticed any weird tint shifts or anything like that. If the SST40 throws like the SST20 then the Luxeon is more flood than throw. Pleasant beam. Beam pattern seems to be on par with the 219C. Give or take a pinch.
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!
What’s fried is likely the driver, not the LED. 8.4V will fry the circuits which don’t have protection against overvoltage in that driver and also the linear FET will attempt to dissipate (8.4 - 3.4)v*5A = 25W as heat, which is not good for a 17mm driver, that’s the same output as a low end soldering iron.
Are you saying that I might be able to use the SST40 with the biscotti driver? I've never really changed an led flashlight bulb and the last thing I want to do is mess it up, again. lol
