REVIEW β Imalent flashlights pack a very bright punch in very small packages.
What is it?
We reviewed two small flashlights from Imalent. The LD70 is branded as a powerful keychain, with an impressive 4,000 lumens. At just a bit larger, the MS03 fits in your palm with room to spare and packs an incredible 13,000 lumens.

Design and features
Setup
After unpacking these little flashlights from their snug, insulated packages, they needed to be charged. The larger MS03 requires that you unscrew the bottom, take out the battery (and battery protectant the first time you use it) and the charging port is located on the battery itself.
The keychain-sized LD70 has a magnetic port on the bottom edge.
Performance
The flashlights are simple to use, just click a button like a regular old flashlight. However, they do have a couple of extra features.
You double click the power button to get it into Turbo mode. Then you double-click again for strobe mode.
You can lock (and unlock) the flashlight by clicking the power button three times for the MS03 and four times in the LD70.
The LD70 also has a very tiny display to show you exactly which mode youβre in (volts and lumens).
Immediately you will notice how bright these flashlights are. When compared side by side with a regular smartphone flashlight, thereβs really no comparison. Using your phone light isnβt even close, these flashlights are in an entirely different league.
You will also notice, however, that they get hot. Very hot. Very fast.
They do have βintelligent thermal control,β which reduces the power automatically as the housing temperature rises. In the LD70, once the external body temperature of the flashlight hits 50 degrees Celsius, the power automatically reduces to 900 lumens. In the MS03, it reduces to 200 lumens when the body temperature hits 55 degrees.
In testing these, I found the LD70 keychain flashlight got noticeably hot within 2 minutes and by 3 minutes, it was uncomfortably hot. By 4 minutes, it had dropped to 200 lumens, and I still found it uncomfortably hot to hold onto.Β
With the palm-sized MS03, it was noticeably hot in just 30 seconds, which was quite a surprise. Like I said, very hot, very fast. And after about a minute itβs verging on uncomfortably hot, though I held onto it for a few minutes longer and it didnβt get any hotter, showing that the thermal control really works.Β
These flashlights are no joke. And you should handle them with care.
I originally had these in mind to pack with my son for an overnight camp in the woods. But given the brightness and heat they generate, I donβt want to risk a kid getting burned or the real possibility they would, at some point at least, shine in someoneβs eyes. Plus at $60 or $130 a pop, they certainly arenβt a toy. Weβll save them for family camping trips instead.
Throughout the pandemic, as weβve worked on house and yard projects, these flashlights have been great. From spotting a long-lost piece of gear from the recesses of our garage closets to finding our puppy hiding in the bushes on a moonless night, theyβve already come in handy. I can only imagine the thousands of uses for these pocket-sized flashlights and how convenient theyβll be in the coming years. We just have to be very careful, given their small size, to make sure we donβt lose them!
What I like
- Portable, convenient size
- Excellent light quality
What Iβd change
- Less heat generation
Final thoughts
As long as youβre aware they get hot very quickly, youβll be thrilled with the performance of these tiny flashlights.

Not keychain sized. But definitely bright.
I have the ld10 and ld70 but I love my ld10 more, because it doesn’t burn that fast as the ld70, is a thrower and the battery hold more juice. The only con I have with the LD10 is the charging cable setup that won’t stick strong as the LD70.
