Nitecore MH40GT Flashlight Review

Hi, and welcome to CivilGear where I take a practical “on-the-job” approach to reviewing neat gear to help me in my work or with my play, or maybe in this case, epic lightsaber battles!

Nitecore MH40GT CivilGear 394

 

Hmm, I can’t think of anything thing else witty to say by way of introduction as I fear anything else would just come across as descending to teenage metaphors about size comparison … OK so let’s get to central feature of this light, beam distance! What’s that saying again? With great distance comes great … um … narrow beams … sure, I’ll go with that.  So with that in mind, this light is great for up close and looking through narrow openings or for lighting up a decent area far away. If you are looking for a top notch rugged and even rechargeable search/spot/thrower light, then say hello to Nitecore MH40GT!

Specs

Spec sheet from Nitecore; notice that the 18650’s perform much better in this light. Also note that the 18650 run times is for two 3400 mAh batteries; I used two 2,300 mAh and I got a total run time of 1.5 hours on turbo.

Beam Profile

Nitecore does not advertise the beam angle but using a protractor I measured the main spot to have a total angle of about 20° and a total spill angle of about 60° .

Warranty

Because the MH series have integrated charging Nitecore provides only a 1-year warranty for free repair, so make sure you only buy from an authorized dealer (you can contact Nitecore’s customer service do find one) or you will waive your rights to the warranty . Also, take care to store your light properly, as the warranty does not cover damages caused by batter leakage. Check their website for their full terms of service.

Operations

I want to say up front that MH40GT’s operations (just like that of the other MT series) relies on the old-school method of tightening and loosening the head. Once you actually think about it, this is definitely a two-handed light, unless all you want it turbo. Turbo mode is tight, all the rest is loose. In my opinion, this light doesn’t have what most people nowadays would call “mode memory” which comes mainly from electronics. This list has what I would describe as a “physical memory” due to the twisting of the head. Since the there is only one option in the ‘tight’ position, this is how you “store” the mode you picked in the USER-DEFINED mode. A little hard to understand if you’ve never used a light like this but check out the below video and some step-by-step detail.

Built-in Recharging

The light has an integrated battery charger which is very helpful for those using a light everyday and can charge up the batteries without having to take them out all the time.  I got a total charge time of about 3 hours for two 2,300 mAh batteries and using a wall outlet and the wall adapter supplied by Nitecore. The system uses a barrel pin connection and tiny indicator light for what the unit is in process or done with charging.

One quirk with the system is that once you plug in the power cable, you have to click on the light (the light won’t actually turn on) to start the charging.  The power connection on the light is  protected by a very robust metal screw around cover.

Pros

  • Unimaginable throw!
  • Rugged head, can toss this in a tool box and forget about it
  • Can still be utilized even in ambient daylight
  • Doubles as tactical baton
  • Stays pretty cool on turbo
  • Custom belt clip actually works well on belts, and does not get hung up while taking the light out of the holster.
  • Integrated charging for serious daily and duty use
  • Holster has three attachment methods, one of which is a great metal D-ring

Room for Improvement

  • Only 2 modes mean that the “hidden modes” like SOS and Strobe cycle during the primary mode
  • Have to “lock in” your user mode by putting the light into turbo mode. Every time you turn the light on and you want it to remember your user mode, it has to turn on in turbo.
  • The holster flap is either too long, or the holster allows the light to sink lower than expected, which results in the potential for the light to fall out of the holster in extreme cases of movement.

 

On The Job

Once I got this out and found some open spaces, I really found out how much throw this thing really has! After the initial awe I started  using the light on the job and found out that I really needed flashlight for narrow spaces and for use  during the day time, and this worked great for both!

All pics below are in turbo mode.

Checking out the crane pad ~200 feet (~60 meters) away.

 

Inspecting bridge expansion/construction joint (~75 feet / 25 meters away). Small beam spot can be useful for reducing  excess light light spill which might distract road users.

Inspecting an 8ft deep, 6-inch diameter sewer clean out. Again, the narrow beam angle makes seeing down laterals a dream come true!

Thoughts and Wishes

  • Charging system uses a barrel pin connector to minimize charging time; however, I would prefer a USB port, like may of their other MH-type lights so I can charge it pretty much everywhere
  • I wish the clip was attached more as ring instead of clipping on.  Since the light is so long and can have more leverage than normal, it’s not that hardest thing to pull the light off your belt incorrectly and have the clip pop off.

Price

You can probably find this on amazon for around $110 USD, check the links below for current pricing.
