This is just what I was hoping for. I have a StreamLight ProTac HL that I have used for years. But now I need it for blackout, light discipline areas. This red filter is perfect. It doesn't fit exactly but with a thin strip of F4 tape it is super snug and will not slip off. The spring hinge holds the cap firmly open when I need it so it isn't floppy. Form, fit, function.

This is an excellent optic and flashlight for your handgun, bar none. This is not about that, this is about the fact that streamlightoutlet.com cannot discern between the two models, one that is end of life being the TLR-7a and the new TLR-7x clearly described in this product. And to be clear, there IS a difference as described by the vendor, Streamlight. I spoke to them directly and the new 7x supports the use of more powerful rechargeable batteries. The circuitry that controls, the LED has been updated in this model. Using rechargeable batteries in the 7a WILL cause damage and failure. I received the 7a instead of the 7x. Unfortunately, PER streamlightoutlet.com, they cannot reliably have you return and get the right model. This is largely to due to the fact that the SKU 80926-69424 is identical on both. So this falls on StreamLight as well. For now, you should purchase this elsewhere like opticsplanet.com that definitely know the difference. If you got a 7a, return it for your money back from streamlightoutlet.com.
