Headlight unit for special version of 3D printed tricopter, uses CARLCO 20mm TIR optic in holder, that gives you lots of choices of beam pattern to suite your flying needs; from spot light “tight” beams of light to a wide diffused even “wall of light” and even an oval beam option optimized for fast forward flight [when orientated vertically].

• JR style servo plug
• Utilizes separate MCPCB for heat wicking from LED
• Simple jumper to select power source (JP1)
• Current selectable also via jumper (JP2), either 350 or 700mAh
• Cree XM-L2 makes 110 or 350Lm (depending on current)

Can be controlled one of three ways

• On anytime 5V is applied (JP1 closed)
• Switched by enable signal (pulled up) from controller, separate 5v source can be constantly supplied (like from BEC), this removes the load from the FC / MCU pin used for remote control (JP1 open)
• PWM’d for brightness control. This requires additional coding and a spare HW PWM pin (JP1 open)

Note tho 700mAh is VERY LOW power for an XM-L2 because there is no physical heatsink it’s highly advised to use a DIRECT THERMAL PATHWAY MCPCB such as a SinkPAD. On top of the DTP for heat a Copper MCPCB will provide a decent bit of mass to more effectively disperse heat into the air. A copper MCPCB should also be reflowed directly to the via matrix for both better heat transfer and a more secure mount for the LED / optic.
