The new SureFire M640U Scout PRO is an update to the classic M600U Scout light. As an all-around great weapon light, it’s built to take abuse and is one of the most proven and reliable weapon lights on the market. This model differs from the classic in that it has a swivel mount that allows the end-user to bend the body of the light to sit closer to the rail, making for a more compact weapon light setup. It can be mounted to standard 1913 Picatinny and M-LOK rail and has a rear click tail cap with momentary and constant-on function.

It runs on two CR123A batteries and has 1,000 lumens and 11,300 candela which makes it effective at close to medium range. Positive identification on a target in total darkness at 40-50 yards is about the most you can rely on. Beyond that, you can make out a target within 100 yards but the details will not be easily discernable. The beam is more flood (wide) than a spot but is great at what it does.

FAQ

Is there any difference in output between this model and the old M600U?
Nope! The only difference between this model and the previous M600 model is the mount. They both produce 1,000 lumens and 11,300 candela.
Will this fit on the T.REX Lightbar?
It won’t work without an adapter. You can pick up a PRO mount adapter for the Lightbar HERE.
What is the difference between Lumens and Candela? Which is more important?
The number of lumens a light has can be very deceiving. Though high lumen counts are often thrown out by manufacturers to sell lights, higher lumens doesn’t always translate to a brighter light. Simply put…

Lumens is the total amount of light emitted.
Candela is how far and tightly focused the light is thrown onto a target.

Lumens is important, but Candela is king when it comes to identifying targets. Lumens can light up a room (flood light), but candela can light up the details on a particular object (throw light).
