The only other real perk to this light is it does use two 26650 batteries with a output charge port so you can use it to charge other devices.

First, the 90,000 lumens claim is hilarious and a blatant case of false advertising at minimum. Lumen meter testing indicates is maybe 1.7% of the claimed output (for those that don’t want to bother with the math, the actual output is maybe 1550-1600 lumen with fully charged batteries before the light heats up and output drops off a bit). My Streamlight Protac that only claims around 3500 lumens is far brighter.

What are lumens?

There are six total settings, including a middle output of 4,200 lumens and a low output of 1,200 lumens. A built-in thermal control module will automatically adjust the brightness output so that you can use the flashlight comfortably without overheating. It is the successor of the very popular BLF Q8, which has been a very popular light amongst flashaholics and has been a hit amongst flashlight enthusiasts from all around the world.

Super Bright & Long-lasting: This high lumens led flashlight is super bright,easily light up an entire room or an entire road or mountain on the darkest of nights. The brightness is 20 times brighter than old incandescent lights. Long lasting flashlight is one of the best choice for camping accessories and gear. Usually what happens with LEDs is that the manufacturer specifies the output at something like 1/3 I_max at 25 C junction temperature, which gives a grossly exaggerated estimate for Lm/W and then people who build devices using the LEDs simply take the figure as given and think that the LED will output so-and-so many Watts at full output, when in reality the output can easily be half of that. All that being said, the light is a decent around-the-house light. The side light is a cool option for lighting an area while the flashlight is resting upright on a surface and the low setting for the side light does allow you to have at least some light for hours. USB Rechargeable: High Lumen Rechargeable Flashlight included high capacity rechargeable battery and USB cable,This high Lumen flashlight could run up to 12hours on low light modes when full charged . Tactical flashlight have 4 Blue light power indicator: 100% -75% -50% -25%, help you see the rest power at a glance. remind you charge this flashlight in time.

Blue light flashes during charging and turns blue at the end.Note, most of the flashlights on this list don’t follow the ANSI FL1 standards for their highest output, and just note the maximum available output instead. I've used [the Fenix PD35R] while walking around at night and had it light a path for me, and at the same time, it could have been used for shining it in someone's eyes if they tried to harm you in some way, or possibly rob you," Short said. "In other instances, I have used it for looking under the couch in my house for a toy my little girl has 'tragically' lost and is in direneed to find." The problem for photography isn’t so much the rise and fall times, but sustaining the flash for n-milliseconds while the shutter is being swept across the frame. The MR90 combines 2 flashlights in 1, with 2 different kinds of LEDs. There are 8 high-power LEDs in shallow reflectors to give you an extremely wide beam (see our review), and 1 separate LED inside a deep and bigger reflector to throw a beam 1150+ yards.
