Electro Bob decided to upgrade his Ikea halogen spot lights into using LEDs so that he could run them all night. Bob removed the guts of the spotlight housing and installed his new high power LEDs which were mounted to two L brackets for heat sinking. I would have never thought of using orange LED like Bob did but he says that they are easier on the eyes at night.
“The LEDs used here are 350mA types, but I made a constant current supply to use them at about 160mA because this provided good enough lighting. In this setup, even in the closed spot light, the heatsink barely heats which means that there is adequate cooling.”
