[1.67 lb] I bought this lamp for six reasons.
1. You can use it hands free, very useful when you are hauling your photo gear and a tripod.
2. You can adjust the angle of the beam by turning the light on its central axis
3. You can adjust the size of the beam by rotating the front lens.
4. It can produce a bright light of 1000 lumens
5. The rechargeable battery has enough capacity to produce 1000 lumens for a couple of hours and by choosing a lower lumen light options (available through light switch) it can go much longer.
6. It is USB chargeable.

In the couple of months that I have used it, it has performed beautifully on all counts. I am impressed. The only remaining item is long term reliability but so far a great job indeed.

I have often found it far easier and more comfortable to wear it around my neck (rather than on my head) as I am usually wearing a winter jacket and found this way to be far more comfortable with the elastic strap going around the collar of my parka and the battery hanging over my chest.

I do have a suggestion regarding charging it with the micro USB cable supplied with the battery. Instead of disconnecting the micro end of the cable from the battery box, keep the micro end of the cable permanently connected to the battery box and tie the charging cable (after folding etc) with a velcro tape to the coiled cable which connects the battery to the lamp. Then use the other (regular USB) end of the cable to connect (and disconnect ) to a USB hub. This way there is no danger of damaging the micro end which is built into the battery holder and any damage there shall render the whole light worthless and such damage is not easy to repair. In other words, leave the micro end permanently connected.

All in all, I am very satisfied and , in my opinion, it is a great value.
Five stars.

[10 x 6.4 x 3.5"] 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.
