    There's a new generation of LED technology that's been around for
    a year or so. This includes high power LEDs which have to be used
    in a heat sink to keep from overheating. One of these in a
    flashlight can be brighter than some of the last generation that
    used 13 "high brightness" LEDs and supposedly matches or exceeds the
    brightness of much larger flashlights that use Krypton bulbs.
    They're also used by some police departments which require lights
    bright enough to be useful as weapons (momentarily blinding the
    perps). They probably could be used to replace photofloods, but
    you'd still have to use a lot of them, meaning they have a ways to
    go before they'd be cost effective. As for color, get a box of one
    type of LED and their colors will not all be identical. One
    manufacturer sorts the LEDs by color and sells regular bluish-white
    flashlights at the regular price as well as a white-light version
    using the selected LEDs, that sells at a slight premium.

    And what would the manufacturer, catalog number, and web site for these "high brightness"
    LED flashlights ... i want to buy (at least) one!

    You'll find complete flashlights as well as drop-in replacement
    "bulbs" for Mini-Mag flashlights. These URLs should keep you busy:

    Thanks for that ... I just picked up another Maglight, and maybe I'll try some of the high
    power LEDs in it.

    In the larger Maglights (C & D cells) the LEDs may not be as
    bright, at least when the batteries are fresh. The LED's brightness
    stays relatively constant however, and I've taken batteries out of a
    Maglight that were so weak the bulb's filament didn't even glow
    faintly. The same batteries seemed like new in an LED light. It's
    the smaller (AAA & AA) versions where LEDs really excel in
    comparison to bulbs, even when fresh batteries are used.
