You sir have made my day, thanks.
 
The color range for LEDs are limited to a spectrum, say 3000-6000 kelvin. hence with the same lumens, they will not be effective as incandecent.

On the flip side, the human eye does not like the higher kelvins as much, which explains why it is more blinding than a zenon. It also appears brighter, but that is only an illusion due to the amount of glare it creates for our eyes.

In a tactical situation, LED is very effective to disorient the reciever, but for illumination purposes, it is not as clear as a icandecent. Incandecent covers pretty much the entire spectrum of light, including infrared. This is the reason LED is still not mainstream for all applications, they do not bounce enough color information back compared to an incandecent.

Try shining a LED in deep fog, and compare it to a incandecent light. The LED will always fail to cut through compared to a traditional zenon light.

The technolgy for LEDs are catching up, but it is still not ready to replace incandecent yet. You still need around twice the lumens to match an incandecent in terms of effectiveness.

LEDs will hold up to recoil for sure.
Surefires website even goes into detail saying their xenons have shock absorbers where the LEDs don't need them.
But supposedly the white LED light isn't as blinding as the yellow light from xenons, or at least, that's what one flashlight vendor was trying to tell me.
Flashing my 120 lumen LED in my eyes takes longer to recover from than the 200 lumen xenon bulb I have for the same light.

Oh and in response to Magnum Peanut, and in keeping with the Doom theme.
In doom 3 you can't even have hold a gun up at the same time as shine the flashlight, yet I still chose the flashlight in the most demon infested areas where it was too dark to see.
It was my guiding light and my friend. Then when they took it away from my, both my spirit and heart broke...

But hell, yeah stick it in the mag fed. Best of both worlds there.

Thanks for the feedback.
It uses a twist on, 55 Lumen 3-watt 100,000-hour T bin Luxeon LED, run off one CR123 battery.
Good question Beer Drinker, i will be doing some test firing this weekend. I am keeping my fingers crossed...hah.
Oldranger,
I have discussed a production run with my machinist but there are some potential issues that I would want to prove out before selling them. My main concern is the tolerances on the barrel ring location from gun to gun. If anyone has another 870 or grizzly in the kelowna area for me to measure it would be appreciated. Worst case the housing would need to be fit to each gun, this took about 10 minutes to carefully sand off about .005".
If there was enough demand I could probably do them for $200. The majority of the cost is in the machining. I used 6061 T6 and had it anodized black.

$200.00 i think that is a little over kill. maybe at 50-80.00 i can see it selling.

What type of light did you use?
I've seen some impressive lights come out of http://www.dealextreme.com
They've got a DIY flashlight section and pressure switches for several models they sell.
One of the guys at my old work had a little one cell CR123 light I was very impressed with. Almost put my three cell Pila to shame.

Good job. I might have to steal the idea when I get my shotty.

I bought an LED from dealextreme for my Grizzly mag fed flashlight forend to replace the light that came with it and it is the most powerful light I have ever seen. It's blinding.
