The NiteCore TM38 is an extremely powerful LED flashlight. The 1800 lumens produced by the Cree XHP35 Hi D4 LED seem quite standard. Something we see more often. But the range of 1400 metres according to the ANSI standard that NiteCore achieves is very impressive. Few flashlights can manage to shine so far, especially from such a relatively compact light.
At NiteCore, TM stands for Tiny Monster. In the case of the TM38 it is more Monster than Tiny! The deep reflector of the NiteCore TM38 bundles the light into a very tight beam with a range of 1400 meters. That's almost a mile! The maximum light output of 1800 lumens comes from a single LED. The energy is supplied by the battery pack with the capacity comparable to 8 18650 batteries. Charge it in the lamp with the supplied 220V AC adapter. The TM38 can be mounted on a tripod so that you can also keep your hands free if that is convenient.
The lamp contains a display where all important information can be read: the current light mode including the light output in lumens, the battery voltage, a battery indication, the burn time in hours in the current mode and the temperature of the lamp. With the button next to the display you can go through the different positions. The battery voltage can also be read when the lamp is switched off. Even if the lamp is in the lockout position, this is shown on the display. All information is always at hand.
You control the lamp with the side switch. It works a little like the shutter release button on a camera. Press all the way down and you'll go straight to the highest position. But it can also be half-pressed. This allows you to switch between the different lower light modes. Around the button is a luminous ring that flashes every 3 seconds in standby mode to easily find the lamp in the dark. This requires little of the battery, so the lamp will last a long time.
The light modes of the Nitecore TM38:
- Turbo (1800 ANSI lumens, 4 h)
- High (800 ANSI lumens, 11 h)
- Mid (400 ANSI lumens, 22 h)
- Low (200 ANSI lumens, 40 h)
