The M640V is a solution for anyone who desires to have white light and infrared illumination in one solution.
From first glance, many folks will see the lower lumen output of this amazing weapon light and write it off. We will happily report that this light packs performance and versatility into one flashlight. We run these on several rifle platforms and won’t hesitate to consider this a weapon light capable of being a primary lighting solution.
Where does the Surefire M640V Shine:
The M640V, although lower in white light lumens, puts out a deceptively high amount of light. What we mean is that although the lumens are low, the beam pattern and spread pushes the light out far. Compared to the M640DF, it features a tighter beam pattern which results in high performance downrange. Give the head of the light a turn and IR mode can easily be activated for night vision use.
Adaptability and expandability is key.
Aftermarket support and internal support are key attributes for surefire. A host of different switches and tail caps are available for the 640V. The one downside is the light comes only with a push button tail cap. This simply means end users who desire a pressure pad activation will need to purchase a tail cap and pressure pad separately. You can find those products HERE.
If you are on the hunt for a potent infrared light that can also be used as a primary white light, the M640V might be a great fit for you.
