[2x LED] Very nice unit. Very bright at the highest mode. Only downside is that it will time out in about 10 seconds do ur does not get too hot. Overall would recommend and I would buy it again.

[1700 mAh ] This flashlight is nice and lightweight. Excellent for walking/jogging with. I like the beam pattern with the highest intensity in the middle and a (still fairly bright) ring around that.

I also like the quick-access 1 lumen mode. This is really good around the house (e.g. getting up to grab a glass of water at night without turning the lights on).

I haven't been in a situation where I'd need to use the strobe/SOS/location beacon modes, but they seemed to work well when I tested them.

I've used this light with both the 21700 cell it comes with and some 18650 cells I've got. The 21700 cell powers the light for a noticeably longer time than my 18650s do, though I've still gotten 20 minutes on high.

[1700 mAh ] I have used this flashlight in my night photography and found it to be very useful. Low beam is just right for checking and resetting camera settings while the bright and extra bright settings are good to light the way in rough terrains. Battery life has also been good meaning that I can finish a night's shoot without changing batteries or recharging one.

[2x LED] Love this light. Quality, the body is solid metal, metal buttons, lcd control panel. It's got perfect beam focus (more of a flood than a spot), daylight bright if you use 12K. But the softer mode work great as well. Holds charge for a ridiculous amount of time. Super product.

[Stainless Steel] Very compact in size yet super powerful. Beautiful finish, nice accessories included (clip, holster and lanyard).
So far a very solid product. Very happy with the purchase. My favorite flashlight, always on hand.

[ 37 Hours] Been using mine for over 2 years. Has outlasted all of my other flashlights. I use it every day for hvac work and on weekends.

[1700 mAh ] I purchased the MH41 to use as a safety device while I run. Since I run at a very early (before sunrise) time in the morning and on a road shoulder, I need reflective clothing and a good illumination and signaling device to let drivers know where I am. This light functions very well for that purpose, but it is heavy. The turbo mode is extremely bright and overall the flashlight illuminates a long way off and has an efficient spread of white light from central to edge. I don't do Search and Rescue, but I would expect that it would be useful for that purpose, since it has a signaling mode, beacon mode and the necessary brightness to light a good area of territory. The flashlight comes with two rechargeable (in the light) 18650 Nitecore Li-Ion batteries, charger, lanyard, spare tail cap, etc., so it is a good value for the price. It is also waterproof, so you can use it in the rain. I can comment on the use of this flashlight for Law Enforcement also. While it would be useful as a general-purpose flashlight, as well as a self-defense, non-lethal weapon, it is too large and heavy to carry on a duty belt. It would probably best be left on the right front seat of a cruiser during rounds. For searching indoor and outdoor areas, it is very effective, due to its versatility and throw, so it's more of a general-purpose light. The light is so bright, however, that it will probably blind anyone who looks directly into it while on turbo mode, so each agency will have to determine policy if it's to be used for non-lethal defense. The only problem I have with the light, other than its weight, is that warranty service is done in China and the light has to be sent to B&H for them to forward it to the manufacturer for warranty service. That takes lots of time, so I figure that two to three months to get the light back is realistic.

[ 37 Hours] I really like the feel of this light in your hand!! It's really super bright with good adjustable light outputs!! This light is really made for long distance throws!! The bean is really tight with not much spill! Good for hiking or just to play with!! I like it though!! Real high quality all the way!! Made really well!!

[ 37 Hours] It's perfect for key chain carry. This light is nice and small and bright at 700 lumens. build quality is very nice being all metal and the magnet holder is strong enough so you will not detach it and lose it. This light is 2 or more years old and it will be replaced soon.

[0.425 lb] I have a similar flash light for years and it works very well. I also bought two other for family members
