I'll agree with electrothump that the Ledlenser H7 is a great light, but I must admit I have replaced mine under warranty a few times because the hinge that allows the head to tilt forward is simply CR.P!. It let's down this otherwise fantastic headlamp. If you can mod the hinge somehow it would be great.
bedazzLED, you hit the nail on the head with the hinge being crap. The first one I had go bad, had been left on my truck dash in the sunlight. I thought the sun did it. The second one lost its grab while inside my house. I don't know why that one gave up the ghost. There is a real simple fix for the hinges though. You need a 1 1/8" # 2-56 screw, and nut. Remove the hinge rivet, and replace it with the little screw. It actually works better with the screw. The original way had notches that it clicked into. That kinda limited the placement of the light head. With the screw, you can place the light head in at any angle and it will hold fine. I actually used a nylon insert lock nut on my screw, and it has yet to slip. I've already worn out an elastic strap, and had to repair a broken wire. I wear them for hours each day. I'm pretty sure they were not made for the use I put them through. Coast has really have hit on an excellent idea. They just need to beef it up a little. I still don't like the rubber back plate on the battery box either, but it has yet to fail. Oh, that rivet may try to turn as you drill it out. Just apply some kind of pressure to the back side of it as you are drilling it. You only have to drill one side, and then just push it out with anything small enough to go through the hole. The new screw works fine for that. It takes about fifteen minutes for all of it. If anyone needs a screw, and a nut, I'll be glad to send them one of each. I bought a box of a hundred of each from Fastenal, and don't use that many screws that sized, and it's even more rare for me to use that sized lock nut.. Just send me a self addressed, and stamped envelope, and I'll be glad to send you one. Email me for my address. Or, you can pick them up at most hobby shops.
