    Default LED & Diode?

    Wooooooooooooww for a second :? This has me confused. What's the difference between the two because i don't understand

    Well one uses LED lights to interfere with the laser beam, the other uses a Diode (similar to the ones in a laser gun) to interfere with the laser beam.

    Professor Jim can fill in the blanks.....................

    Yeah that is basically it, two different components. The laser diodes have much more power, while LED jammers need multiple LEDs to be effective...

    Diodes can be a tad bit more expensive as well.

    Follow-up question:

    Does "more power" translate into "brightness?"

    When I viewed the diodes on my LPP's heads, activated by the Laser Tester sold on Roy's site, through my standard digicam, it seemed not nearly as bright as the LEDs on my ZR3's heads.

    Sorry for the stupid question - I'm a biological scientist. ops:

    Plenty of experience with LEDs of the VISIBLE LIGHT type from my other hobby (flashlights), but I'm a total noob to the non-visible, and this is my first experience with diodes.

    Thanks!

    Well, it's "peak power"...
    Laser diodes can handle much shorter pulses than the LEDs can. The laser gun's pulse duration is about 20-50ns, so laser diode jammer pulses are probably a similar duration. But the "rise time" for most LEDs is many times that. So, the LEDs are "on" for a much longer duration and a larger percentage of time, probably making an LED jammer appear to be "brighter". But it is the peak power that makes the difference. To jam the gun, only the leading-edge of the pulse matters, which is why LED jammers are still able to jam.

    ^ After I read that 3 times, professor, I finally understood.

    Thanks for helping out a noob!

    I'd like to add to that:

    The receiver of a lasergun has a filter (high-pass ) that makes it less sensitive to slower rise time signals (Like LEDs). In my experiments with a Jenoptik LaserPatrol, this turned out to be a very important factor. (I connected a scoop to the receiver circuit of the JenOptik and measured how the receiver detects laserpulses)

    The amount of technical knowledge here is truly staggering. Thanks for the addition!

    So basically, diode is the way to go for front and rear attacks then. Is the M20-40 diode then? Also, if wanted total protection, what jammer is the best :?
