Timfish Posted August 4, 2021 Share Posted August 4, 2021 These are instruction for a DIY cannon I designed and was able to have Dana Riddle evaluate for spectrum, wattage and PAR. The pdf instructions assume someone with basic "lob a blob" soldering skills and a basic understanding of electrical circuits. The xlsx document has spectral output, wattage and PAR map @ 9" using 16° lenses for the LED stars (other lenses are available). The basic 2 star & buckpuck circuit lets it be configured as needed. For example, the recessed fixtures in this video used 13 sets on a 4" x 12" heatsink to make ~250 watt fixtures. 3500 PAR LED Light.xlsx DIY 3500 PAR Cannon.pdf Quote Link to comment Share on other sites More sharing options...
