LED holder for the I3 Mega and Mega S. The matching LEDs are available, for example. here https://www.joom.com/de/products/5dca77e18b2c370101395570

Unfortunately, the LEDs got very hot on me (over 100 degrees). I then bought a step down module and regulated it down to approx. 11 volts, as my power supply unit output 13 volts. now they are about 35 degrees warm. Step down modules https://www.joom.com/de/products/5e217f3036b54d0101bcff9d
