I like it. I have a 870 HD that I am looking to put a Surefire on. Is yours the 6 or 9V model?
Thanks!
Mine's the 6 volt, no real need for the extra power or weight up front with the shotgun to go 9 volt.

If you want more power than the 6V system but don't want to get the longer 9V system, could I suggest the KL5 LED head on the 6V system? Its 100 lumens for 1 hour, then 3 hours of usable light thereafter. No bulb to break and just replaces the regular xenon head on the 618 series, plus saves you a battery and should weigh about the same for calorie counters.
I am not sure if someone has tried it before but I inquired with the Surefire Tech support and they suggested the KL5 for higher output and reasonable life with the 618 system. I'm ordering up the 618FA and KL5 this weekend and I can post an update if wanted.

Ordered through Grant at GR Tactical. I'll try to post side-by-side images of beam output at various distances when they come.
Surefire tech didn't say how shock resistant the KL series heads are but since they suggested that I put one on an 618 unit, I assume they've tried it before. LEDs are also solid state and the gallium arsenide (light emitting part) is encapsulated in polycarbonate, acrylic, or some sort of solid translucent plastic. I believe Surefire uses Luxeon brand LEDs too, which is one of the high end LED companies, and Luxeon to my knowledge does a burn-in on some lines to weed out the bad ones (bad ones usually go immediately). I've never had an LED die under normal usage unless you try to lower the current limiting resistor and burn it out by running too much juice (don't ask).
I only have an LED Streamlight TLR-1 as reference as far as LED-based weaponlights and everything looks solidly SMD soldered to a PCB with large tabs for more holding surface. I would assume Surefire does at least just as well. I guess I'll find out soon

I started a thread as I've gone ahead and tried this combo. 100% plug-and-play. Read about it here:
