Streamlight 66210 MegaStream USB 1800-Lumen 26000-Candela Rechargeable EDC Flashlight Includes Rechargeable Battery, USB-C Cable, and Holster, Black

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.

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.

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.

Way more powerful than I really needed, but it lasts a long time on a charge. It fit all the bills of everything I needed for my job, and gets used daily. It's well made, give's off a powerful beam that can really light up the dark, and can take drops while still working. I only wish it was more waterproof. My washer killed the last one.

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.

This flashlight is seriously bright. Like, I knew it said 1800 lumens, but nothing prepares you for how much light this thing throws. It cuts through darkness like it’s nothing, and the beam distance is wild — perfect for night walks, emergencies, or just feeling like a superhero in your driveway. The build quality feels premium and solid without being bulky, and the USB charging is super convenient. One charge lasts me a long time, even with regular use. It doesn’t overheat, the switch feels sturdy, and the size is perfect for everyday carry. If you want a flashlight that’s reliable, insanely bright, and actually worth the price, this is the one. Streamlight really doesn’t miss. I cannot function at work without it.

This is a bright light! Its illuminates areas 50 yards out. Great light for security work or camping, easy to transport, good quality, and is USB rechargeable. For what you get it is a good vale. The only down side to it is that the bulb gets really hot. After lighting up a vault to replace a pump, I grabbed the light from the front then promptly dropped it into the water. Two lessons learned: 1: Grab it from the back it is hot. 2: It is water resistant and will handle a short time underwater.

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.
