besides making the 600 solder joints this light calls for,,,(hahaha) its super cheap to make around 25 bucks, and it should be way more powerful compared to any light I seen on the market, I just wanted something to light the entire engine bay up but not get hot like flood lights etc.. I checked all the math so it seems this is how it gets built or at least how im building it.
138 leds --- each 10mm 0.5W White 290,000MCD
DC Forward Current: 100mA
unit draws 4.6 amps total
3 x 46 array uses 138 LEDs / and 46 22ohms resistors
the power pack is 6amp 12volt
im still waiting on the resistors to finish it, but you get the idea,, rows of 3 leds down the entire tube,,, the tube I got at home depot for 4 bucks it was 8ft long and used for protecting florescent tube lights, the rows of 3 will connect to the 16g bare wire I ran down each side
