Parabolic reflector for 100W LED

thingiverse

So I wanted to create a parabolic reflector similar to the Stratus LED Reflector, but I didn't have enough money to buy it just for making some homemade LED flashlights. The design should accommodate most 20-100 W LEDs. The holes for the screws are spaced 34 mm apart (from their centers). I used M3 bolts. To get the best results, you should likely coat the inside surfaces with some silver or chrome paint so that the light bounces off the walls effectively. Take a look at the "Another Reflector" section below as well. Dimensions: * Bottom LED cutout: 25mm square * Hole spacing: 34mm apart * Upper ring size: 114mm diameter
