[1x LED] 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.

[1x AA Alkaline] I use this for night photography with their Red filter (B&H # FEAOFSRD) in order to save my night vision. Works great at 14 Lumens. When needed there is more power than i'll need. perhaps enough for light painting..but I haven't used it for that yet. I was surprised that it didn't have a focus adjustment, however, after using it I don't think it is necessary. the light is round and fairly smooth at all powers. For me the best feature is the ability to set the power you want with the front switch and have it remember that until you make the change change. Previous review wondered why the didn't include a wall charge. Any charger with a USB port (computer, iPhone, Garmin etc.) works fine and I have a whole drawer full of those. Heck, my car even has a USB port. BTW the red filter mentioned above does not say it fits this flashlight, however it is a perfectly snug push on fit.

[1x AA Alkaline] 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.

[0.25 lb] A family member had one of these in the desert and at night it could light up things three states away. I am kidding, of course, for those of you lacking sensors. I've got a bit of a flashlight habit and this one is still my favorite.

And the reviews for this? You're knocking it because it doesn't come with a charger. Big deal. Lots of products don't come with chargers these days.

And one person knocking it because of TOO MANY brightness levels? !? Really? Please stop reviewing anything.

Some people have too much time on their hands.

[1x AA Alkaline] Got this for work in dark areas, brighter than my other lights by far!

[0.25 lb] I was looking for a small bright flashlight that used a single AA battery and this product delivered. This flashlight is sturdy and well designed.

[1x AA Alkaline] 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.

[1x AA Alkaline] 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.

[0.25 lb] I was very pleased with this light. I have a number of flash lights with around 10,000 lumen. This is one of the best with it's shape and design, it a keeper.

[Aluminum] The light works well to provide a variable amount of light in a 180 degree arc, which is what I needed.
