My other flashlight.

"1 Watt L.E.D. Upgrade & IQ Switch® Combo" by Nite Ize.I have had one of these kits installed on a Mini Mag-Light for a couple of years now and it is great! The kit includes a replacement for the bulb and a replacement for the tail-cap. Simply replace the tail-cap, reflector and the bulb. You may have to turn the new bulb if it doesn't work right the first time, as it has to go in one way only. With the new reflector, you will screw the lens assembly all the way down, it won't turn the light off as the old one would, if it does, push the new lamp in the rest of the way, that should fix it.

The new lamp will put out a nice bright spot, I have not been able to get a real intensity level published for it, but it is nice and bright. I rarely need anything brighter for day-to-day work.

The tail cap is the magic here. It has a recessed push button switch and marker light in it. The marker light flashes once every 5 seconds or so. The switch will cycle through the 5 modes if the button presses are within 2 seconds of each other, if slower, the next press will turn the light off.

• Full power - 100% - approx 7.4 hours with alkaline batteries (calculated)
• 50% power - approx 15 hours
• 25% power - approx 30 hours
• Slow strobe - approx 50 hours
• Fast strobe - approx 15 hours.

In addition the light will flash for a few seconds and go out after 14.5 minutes. I have had to replace the batteries a couple of times, each time it seems that the batteries were dying of old age rather than over use!

I had a "No roll bezel ring" (rubber ring around the bezel) but it would not stay on anymore and got lost. It wasn't much use to me anyway.

A couple of modifications I have made, one was a reflector strip around the side of the bezel, the other was to add a ring of glow in the dark material around the lens of the light. (This is not my light but another done similarly.)
