Explorer Series
The Explorer series of lights have 7-modes with dual side switches and Cree XP-G R5 LED. Also has a red LED indicator light on the side switch panel which is used to indicate battery voltage, as a locator beacon, low battery indicator, or just a low-level red light. Hidden modes for variable Strobe and SOS are available by holding down the On or Mode switches while light is off. Review of series: Selfbuilt.

Multi-Task Series
The Multi-Task Series are 2-mode lights with a forward tail clicky for power. The modes are selected by tightening or loosening the head. Tightened, the light is in Turbo mode. Loosened, the light will be in the mode last used. While loosened, the user can cycle through the modes by turning the light on and off quickly. The user modes are High, Medium, Low, SOS, and random Strobe. These lights are very similar to JETBeam models PA10, PA20, PC10, PC20, and BC25. Review: Selfbuilt

But for continuously variable output based on the angle the light is held, the light can be turned on in the up position. Introduced in July 2012. Review of series: Selfbuilt.

Also has a charger port so that batteries can be charged while in light. Introduced in September 2012.

Past Lights
NiteCore developed the SmartPD user interface based on the piston drive. The battery fits in a metal sleeve (the piston) which slides inside the body of the light and is activated by pushing the piston into the head to make electrical contact. This mechanism allows the light to be turned on like a twisty or by pushing the tail of the flashlight. The minimum light level is instantly available by double-clicking the switch. Maximum is available by clicking and holding the switch. With the light on, holding the switch in will activate variable ramping and allow any light level to be locked in by releasing the switch again. By loosening the head somewhat, the light can be used with momentary on. This UI has been replaced by the SmartPD SP system which does not have the ramping. Due to the popularity of the original interface, however, a limited edition Tribute Edition D10 with a Cree XP-E R2 emitter was introduced in February 2010 by Battery Junction. YouTube video
