Emisar D4KTI 21700 HIGH POWER EDC FLASHLIGHT

NTG35 LEDs are recommended for good tint, beam pattern, high CRI and free of greenish tint.

Emisar D4KTi puts a high lumen output but generates a lot of heat at the same time, please acknowledge before purchasing. Unprotected, flat top battery works only (not included in the price), D4K does not work with protected battery.

The Lume X1 boost driver upgrade is available for the Luminous SST-20, SFT-25R, Nichia 219B R9080, Nichia 519A R9080, NTG35 LEDs etc, 3 Amps per LED. The boost driver is not compatible with Nichia E21A, Nichia E17A or the mule versions of the flashlight. Note that the boost driver output is limited in comparison to the default driver, it is more efficient (90-95%) with a longer running time and less heat.

The Lume X1 is a high power driver - for best performance, recommended to use low ESR, high CDR 21700 batteries such as Molicel P42A, P45B, Samsung 50S, 40T, or Vapcell T50. Please note that this flashlight is not a toy and must be operated responsibly.
