The focus works as before and you can get a good tight beam, but with enough side spill for walking. It seems like a decent upgrade for the money, with a nicer white light and while I haven’t run down the batteries yet, I’ve gotten 6 hours burn time without any sign of the light fading, as opposed to about 3 hours burn time if I was using the Halogen bulb. My 8 LED array provides a nicer proximity light, but for the $ spent I can’t complain very much. Now all we need is to get Petzl to provide an upgrade with two 3 or 5 watt LED’s with one set for spot, the other for proximity and a voltage regulator. Allow the lights to work together or independently and keep the total price under $100. I’d send my order in today!

I have an old Petzl Zoom that would greatly benefit from something like this...

The local WalMart sells a NiteIze "LED Upgrade" for a MiniMag that replaces the bulb and reflector with an array of three white LEDs and a reflector that fits around them. Only minus point is that you lose the variable beam feature, though you can still use the MiniMag as a tent (or cave) "candle." The upgrade costs $5.00 or so. I'm sure that some of the cave equipment suppliers sell this kit also, and I've seen NiteIze stuff at Fry's out in the far west.
The only trick to the install is that LEDs are diodes , so you might have to remove the array from the flashlight then rotate and re-insert it to get the light to work. Instructions are on the card the adapter comes in.
