The Nitecore TM38 has a maximum output of 1800 lumens from a Cree XHP35 HI D4 LED that is set in a deep polished reflector for an astonishing maximum range of 1400 metres, which is a 300 metre increase on it's predecessor the TM36 and the beam intensity has also increased by 160%.
It features the NBP68HD rechargeable battery pack that is equivalent to 8 x 3400 mAh lithium-ion batteries and can be charged while attached to the torch via the charging port on the head of the TM38, or independently via the 2 A (3.5 mm) charging port on the end of the battery using the included UK mains adaptor. There is also a second larger 4 A (4.0 mm) charging port that charges the battery faster using a separately purchased Nitecore charging adaptor for rapid charging.
An integrated OLED display allows the user to quickly and easily see the lumen output, brightness setting, beam distance, battery voltage, battery level, remaining run-time and even the temperature of the torch. The OLED display will automatically show these readings when the torch is turned on and then will remain off until you press the small button next to the display to cycle through them.
The light is operated by a single dual stage switch (patented) for easy one handed operation. Two modes are available and are selected according to how far you press the switch. From off, pressing the switch half way and releasing within one second will activate daily mode and pressing it all the way down and releasing within one second will activate search mode. Alternatively holding the switch down, while the light is off, either halfway or all the way for longer than one second will provide momentary illumination and the light will go off when the switch is released.
Once in daily mode half presses of the switch will cycle through ultra-low, low, mid and high. Holding the switch halfway for more than one second will provide instant access to strobe. Once is search mode half presses of the switch will cycle between high and turbo. With the torch on two gull presses in quick succession will enter the special modes and half presses will cycle through strobe, SOS and location beacon.
When the light is on, fully press the switch and release within one second to turn the light off and put in standby mode. When in standby mode the torch will consume small amounts of power to maintain the micro control unit and the power indicator will blink once every two seconds to indicate the location of the torch. The torch can be fully turned off by loosening the battery pack from the head of the torch.
Other features include an integrated power indicator in the switch, a tripod mounting port, which allows the TM38 to be set on a standard tripod, a shoulder carry strap to free up your hands and a built-in thermal protection circuit.

Turbo: 1800 lumens; 4 hours run-time*
High: 800 lumens; 11 hours run-time
Mid: 400 lumens; 22 hours run-time
Low: 200 lumens; 40 hours run-time
Ultra Low: 50 lumens, 120 hours run-time
Note: *The thermal protection will automatically lower the output of the torch if the internal temperature reaches 60°C or higher to prevent the torch from overheating and to protect the LED, therefore this is an accumulated run-time. Do not attempt to cool a heated torch by submerging it in water as this could cause irreparable damage.
