Redily available aluminum "heat sink" for LEDs
I went looking for my long 4 foot ruler to cut something and discovered a readily available heat sink for LED emitters.
It's a 48 in. Aluminum Straight-Edge Rule. Home Depot lists them at $8.86
2 inches wide and 1/8 inch thick. Not optimal for high density installations, but perfect for testing at less than full current.
