Acebeam has recently introduced a brand new flashlight called the T37. Technical specifications reveal that it can produce a maximum brightness of 4,000 lumens and has an impressive reach of up to 440 meters. As is normal for Acebeam products, the peak brightness is only available for a limited duration of one minute. After that, users can enjoy around 3.5 hours of illumination at lower settings. If you choose to use the flashlight at a modest 30 lumens, Acebeam claims the battery life can extend up to 72 hours. For detailed runtimes, refer to the chart located at the end of the article.
Brightness and Battery Features
The flashlight features a cool white LED with a color temperature of 6,500K. It runs on a rechargeable 21700 battery that has an approximate capacity of 18 watt-hours and can be replaced when necessary. Charging is done directly in the flashlight via a hidden USB-C port located at the head of the T37. According to reports, it takes about 2.5 hours for a full charge. The battery status is indicated by an LED on the switch; blue shows that 30% or more battery remains, red indicates a range of 10-30%. If the battery dips below 10%, the LED will start to flash.
User Interface and Design
The switch is designed to allow for a half-press to turn the flashlight on temporarily. Users can change modes using a rotary switch located at the back, which also has a locking feature. The flashlight comes with a two-way clip for easy attachment to a cap or belt, though at 200 grams, it might be a bit heavy for a cap. The total length of the flashlight is 14.5 cm.
The T37 is priced at just under $130, and it is exclusively available on Acebeam’s online store. Currently, it cannot be found in Acebeam’s Amazon store.
