Hi everyone,
I received these lights (4) http://www.dealextreme.com/details.dx/sku.6131 a few days ago and was going to be giving these away as gifts. I found some mixed reviews on it and decided to purchase it anyways. When these arrived, I tested all of these on a set of eneloops all at the same time to make sure they wouldn't be defective. The first 2 failed within 1 hour and overheated to the point they could not be held for for several seconds. I tried to turn the clicky off and they would not depress. The third one took about 1 hour of continuous runing before it suffered the same problem as the first two. I took the lights apart and inspected the clicky switches and found that they had melted as if the switches were acting like a resistor. Two switches melted to the point where they actually fused themselves to the metal contacts underneath and deformed. The third switch (uppermost in the pic) didn't depress at all.
I had one good remaining light left and tried that switch on the 3 defective lights that went bad along with a good set of fresh eneloops. I found all 3 LED's had been damaged due to overheating and they were extremely dim. I should mention the 4th light has been running fine and just getting warm with more than 1.5 hours of constant useable light on Eneloops. It dims noticably after that, but will continue for at least a full 2 hours. I'm afraid sooner or later the last light will suffer the same fate as the other 3.
I've contacted DX about this already for a refund or full credit as I don't wan't to replace these with the same item. Does anyone know why these lights would run so hot to melt the clicky switches? I don't see why a flashlight can't run a set of batteries until they expire without overheating and self-destructing. Could it be the switches that are bad or the drivers?
I have two other lights from DX that have run through sets of batteries continuously and have never had them damaged from overheating. In case you're wondering, they are the Romisen RC-G2 with a 7090 XRE-P4 emitter added to the stock driver and a stock WF-800 (18650) thrower. I'm not an expert at LED lighting and these flashlights, but I do have a prior electronics background and at minimum, basic equipment so I can mod these lights if needed be so that they don't have these issues. This LED stuff is quite interesting and this forum seems to be most supportive and I'm suddenly getting hooked!
Thanks for reading through this post and offering any input or advice that can help.
