The didn't lend anything. The guy at the local SL service center, which is an independent dealer, helped and that was probably out of morbid curiosity. SL themselves couldn't even tell me what voltage should be at the LED or even the voltage output of the battery. All those answers(or lack there of) came long before I let on what I had done to the light. Regardless of what I have done to this light, I have bought two of them....so I should get twice the support!!:twothumbs
