It was only a matter of time before someone made a dedicated weapon light that was powered on AA batteries. The someone is Insight Technology and the light is the WL1.
Insight Technology claims that the WL1 is the first tactical light to run on AA batteries. It features a quick-release rail grabber interface, 90 minute runtime, 150+ lumen output, momentary activation, strobe function, and an optional visible red laser. These lights also feature Insight’s split rocker switch which I am very familiar with from the Insight Technology Procyon and WX-150. It is a very nice system that allows the switch to function identically with both left and right hand manipulations.
While this light will run on alkaline AA batteries, lithium AA batteries will be the smart choice. Lithiums have a longer shelf life and can handle a wider temperature range. Lithiums batteries will be ideal but it is very attractive to have a light that can be run on grocery store AA batteries in a pinch.
I have been using Insight Technology products since the original M3. I have owned the M3, the M3X, the SSL-1, the Procyon, and the WX-150. If the new WL1 works as well as those lights did, it will be a very popular light.
It appears that there is some limited information about the WL1 on Insight Technology’s website. Hopefully, more information will be available soon.
