We end up with an array of 13 LEDs requiring a heat sink θ SA of about 4°C/W, giving an area of 35cm 2. The LED temperature is on the high side at 131°C and the price for the LEDs and heat sink is $47.10. The LED efficacy is medium at 92 lumens/W. With the relatively high temperature, the LED lifetime will be reduced.
