LED Adjustable Chandelier (The Light of Blindness)

thingiverse

This project involves replacing an incandescent ceiling light with an LED alternative, boasting approximately 10,150,000 MCDs. The LED light uses 35, 10mm LEDs arranged in seven rows with five in series. Inspiration was drawn from two Instructables: "Adjustable Lego Lamp Counterweighted" and "LED Chandelier." The materials, sourced mainly from Lowes, include 1/4" acrylic, four 1/4-20 x 1-1/4 bolts, eight 1/4 washers, eight 1/4-20 nuts, a small double pulley, two small single pulleys, an 110vAC to 12vDC transformer, a 4A bridge rectifier, a 330uF electrolytic capacitor, and 35 high power white LEDs (0.5 watt, 100ma, 290,000MCDs each). For instructions on assembly and wiring, refer to the provided video and Flickr set. The process involves laser cutting two big acrylic sections, soldering LEDs according to a schematic, attaching wires, assembling the light, and setting up the counterweight pulley system on the ceiling. Please watch the video and view the Flickr set for further details on this unique lighting project.
