I wouldn't recommend a led lenser h73 to ayone!!! First of all when I went to remove the plug after charging it for the first time the "sealed" unit fell apart leaving the exposed live pins plugged into n outlet!
So I thought it's only the plug the head torch is fine. So I plastic elded the crappy plug back together avoiding any chance of the thing falling apart while plugged in!!
After a week of use the rear slider at the back stopped working and the on/off button was intermittent. In most cases I had to remove a battery to turn the thing off.
Completely useless bit of kit and with the price tag it's robbery
