It is a larger version of the macro. Look at the pic to compare the three sizes. (ear plug for scale) Still pocket sized but so much brighter. The light is really bright adjustable down to a beam useful for close in work. The light has a nice color for working. The switch is convenient and works well. It is easy to swap light levels. It is awesome to never ha e to buy batteries fir it because it charges from my phone charger.

As always with Streamlight excellent product meant for duty. Works exactly for what I bought it for to use as a duty light, needed it to be bright, and be able to use a USB-C to charge it. It's a little bulky, but still fits in my cargo pocket on my uniform pants. I like the slide cover design to cover the charging access port, but I question it's durability with a very thin o-ring used to seal it. Not as good as a Surefire, but the price point is better.

Having owned several Streamlight flashlights over the years, I was eager to find a newer model that offered an even longer throw and brighter beam. The Streamlight 66210 MegaStream caught my eye, and after receiving it and giving it a full charge, I took it out for a night-time test against my current Streamlight ProTac 2 LX. The results were astounding; the 66210 absolutely blew all my other flashlights out of the water. The beam is an incredibly crisp, bright white, and its throw is both precise and remarkably far, easily illuminating distant objects with clarity. What truly impressed me about the MegaStream 66210 is its perfect balance of performance and portability. Despite its immense power, the flashlight is surprisingly small, fitting comfortably in a front pant pocket, making it an ideal everyday carry (EDC) option. Its compact size in no way compromises its performance, which is anything but small. For anyone in the market for a new EDC flashlight that delivers exceptional brightness, an impressive throw, and convenient portability, the Streamlight 66210 MegaStream is undoubtedly my top recommendation.

Excellent light. Works as advertised. Quality, brightness, battery life, etc. all excellent. Purchased both, the MegaStream, and the ProTrac 2.0 Hp. Both exceeded expectations.

I like the size and weight of this light. I wish it had a bit more throw to it and less spill. Also, why can’t Streamlight just allow users to program the good old fashioned High-Strobe-Low mode? The lack of a strobe is kind of annoying. Overall a decent flashlight though.
