Acebeam has just launched a new flashlight, the T37. According to the technical data, it delivers up to 4,000 lumens with a maximum range of 440 meters. However, as is typical for Acebeam, the highest mode is limited only for a short time, i.e., one minute. A further 3.5 hours can be achieved at lower levels. If you only use the flashlight at 30 lumens, you can expect a battery life of 72 hours according to Acebeam. More information on the various runtimes can be found in the chart below at the end of the article.
A cool white LED with 6,500K is installed. This is powered by a 21700 rechargeable battery with a capacity of around 18 watt hours, which can be replaced if necessary. The battery is charged inside the flashlight; there is a concealed USB-C port on the head of the T37 for this purpose. A full recharge is said to take 2.5 hours. The capacity is indicated by an LED on the switch: blue means at least 30% remaining capacity, while red means 10-30%. If the battery falls under 10%, the LED flashes.
The switch itself can be pressed halfway to switch the flashlight on briefly. Modes are switched via a rotary switch on the back, which can also be used to lock the flashlight. A two-way clip allows it to be attached to a cap or belt. At 200 grams, however, it's not exactly lightweight for a cap attachment. Lastly, the flashlight itself is 14.5 cm long.
I’ve been involved in the IT business for over 20 years, first as a Sysadmin (Mac & PC; 2000-2014) and then as a journalist (2005 onwards). I have attended many industry events, such as IDF, Displayweek, Computex, CES, and IFA, to cover subjects like mobile and local networks, Bluetooth standards, and developments in the mobile sector. Since 2017 I have also worked as an aviation journalist, which involves traveling around the world reporting about both planes and trains.

Growing up in regional Australia, I first became acquainted with computers in my early teens after a broken leg from a football (soccer) match temporarily condemned me to a predominately indoor lifestyle. Soon afterwards I was building my own systems. Now I live in Germany, having moved here in 2014, where I study philosophy and anthropology. I am particularly fascinated by how computer technology has fundamentally and dramatically reshaped human culture, and how it continues to do so.
