Groo here
Looking for a special light for my "cowboy assult rifle" [ aka leveraction.
I will be using a Safariland rapid light mount that will take .8 to 1in light.
I am looking for a single cell [ would like rcr123] light with a base switch.
Ideal would be a thrower with a low and high [high at any time,low selectable]
Low should be at least 50 L high 300 L or higher.
Trying to keep the cost down.
Thanks
Where do you want to mount it? What caliber are we talking? One thing I'll say right off is that rechargeable protected cells and WMLs are not a great mix. Recoil can break the protection IC, rendering the cell inoperable. Are you looking for an option for hunting or is this home protection/zombie duty? Reliability may not be as big a deal for a sporting gun but I like primaries for HD.
By "base switch" do you mean a tail cap switch?
The caliber of the gun and the amount of recoil makes a difference. You don't list a specific budget; I can understand trying to save a few bucks but a few things are key. Personally I don't think a light is suited for weapon use if it's not sprung on both ends of the battery compartment. If the + end of the cell rests right against the circuit board of the light engine it's gonna batter it under recoil. That wouldn't be in issue for a lower recoil gun like a .22LR, maybe even a .38 Special in a carbine. My 9mm and .45 ACP carbines don't have a lot of kick but that direct blowback action does deliver a smack to the light.
I'm not aware of all that many inexpensive lights that meet the need and that are also 1 cell. The Elzetta Alpha or Alpha CQB would be superb but they're $150 or so. I'm guessing that might be more than you want to spend. If you can live with a 2-cell light the JETBeam BC25 works very well as a WML. I have used them on my Beretta Storm 9mm and my HK USC .45 ACP at times. They're sprung on both ends of the battery compartment and are quite robust. Just 2 levels of output, a lower setting that's still pretty bright and a 900+ lumen Hi (for the SE version, about 700 lumens for the older one). Maybe a slightly bigger light wont' be in the way on a long gun?
