Very nice, lightweight and good brightness. - Crimson Trace Rail Master Universal Tactical Light

If you are looking for a simple light with momentary or continuous on that is lightweight and affordable, you have found it. I put an O-light Valkyrie on my PMR-30 and it was bulky and made the balance off. Then I got this and it was a perfect fit, lightweight and balanced well.

At 200 lumens this isn't the brightest out there, and it uses the less common CR-2 batteries but overall I would expect this to be a $90-100 light. For around $70 you can buy this light and a big pack of the odd batteries and be in good shape for years of operation.

Also I really like the positive feel of the switches (ambidextrous), as compared to others like the O-light. They are more of a paddle that hangs back off the light, easy to operate bare handed or with gloves. The rubber pushbutton switches on the Valkyrie are less likely to get bumped on, but also seem like they would be very hard to operate with gloves on.

For perspective, I have 2 of the Valkyrie's sitting on my shelf and this light mounted on my PMR. I came here to buy another one of these and still am not sure what those other lights will go on. Maybe the front end of an AR or something, but I am already getting another CMR-209 even though I don't know what to put it on yet.
