Various "generations" of LED's?

    Can anyone explain the different "generations" of LED's? I remember the old lightheads that were comprised of 40+ LED's packed together, since then most have fewer, brighter LED's.

    I have seen lights advertised with "Gen 3" for a while, now I see 4th, "next". Also Whelen "super". Also see lights advertised with LED wattage. How does it all break down?

    It's quite confusing when comparing lights. There is a number of LED's, but not all the same intensity, correct?

    For example... these two body mount lights:
    3, 3-watt LED's ("next generation")

    3 LED's but no mention of wattage ("super")
    http://www.strobesnmore.com/Whelen-TIR3-Super-LEDs.html

    I have no idea which is "brighter" (or are they the same?), and it's very hard to use video as a comparison.

    For the most part, there are really only 3 generations of LEDs.

    Generation 1 (Gen I) LEDs are the small, tightly packed together LED clusters that you referred to:

    Generation 2 (Gen II) LEDs were similar to Gen I LEDs, and didn't last too long in the market because Generation 3 LEDs were released not too long after, and were brighter/more effective.

    Generation 3 (Gen III) LEDs consist of almost all popular LED emergency lighting products on the market today. These are the lights with only 2, 3, 4, or 6+ LEDs in the lights. They are extremely bright and far more effective than the previous Gen I and Gen II LEDs. Generation III LEDs include both TIR and Linear type lights:

    There are a lot of companies out there who claim to have Gen 4 or 5 LEDs out there. The truth is they're most likely just Gen III lights with a different reflector on them.

    It can be quite confusing, but just know that most lighting products today are Gen III.

    Hope this helps!
