As some of you probably read, I had a little problem with my DX80 coming with one faulty led only half lit. Someone on the Tashenlampen forum had the same problem so he let it run on turbo until stepdown and the led worked again. Didn't work for me so I purchased another head from Imalent and it also came with a faulty led. I ran it on high until stepdown, not turbo and now it works fine and has ever since. Since the second head works perfectly, I decided to keep it as the backup and constantly use the first head to test what it's made of. I have used it often, running it on turbo every other day until step down which takes about 3 1/2 minutes and no problems at all. I'm beginning to think the DX80 is tougher than I orignally thought it was and since I have the second head, I'm not afraid to run it on max to see the results on a long term basis.
