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.

This is my second Ledlenser flashlight. They are bright, rechargeable and compact. Best we have ever had!

I just wanted more. I purchased the P18R and returned the i18R.

We love this model. It is the third Ledlenser we have owned and the
most powerful! We live on acreage and use it to check the back
pastures for coyotes at night. We wish we had purchased another
of this model! It is unbelievably bright!

This has a very wide, long beam, which is nice for walking the dog at night on a trail. I particularly like the width of the beam so I can see animals before my dog tries to chase after them. So far, the ONLY thing I would change on this flashlight would be to have a more standard charging port (C, or micro usb)

While I have only been using this new flashlight for a few days it have been everything advertised.

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!!

Incredible brightness from something that fits in your pocket. The 4,000 lumen turbo mode is astonishingly bright. Versatile as well with its 1 - 200 lumen Normal mode options. I'd say it a must have for going out at night anywhere whether you need it to read something in the dark , find something you lost or temporarily blind someone with its 4,000 lumen option !

Great for flash light. Amazing for self-defense

This is an awesome light. I saw video reviews of it and finally bought one. The light color/temperature is like snow white. The head moves fluidly when changing the zoom. Also great that the light operation can be customized (had mine reversed to turn on low and the go med and high). I liked this light so much that I bought a spare to keep in the car.
