I still believe how cool it would be if you had to build all of your equipment to make beautiful images. So with that in mind, I set out to build my own led fresnel light. I’m pleasantly suprised with the result. Trust me when I say me and electricity are not exactly best buddies!!!.
I started out with a 100 watt L.E.D chip mounted on a heat sink and a cooling fan. Some 6 inch plumbing fittings and I’m on my way. I mounted the led assembly onto a 4″ abs tube and attached it to the back to hold it in the fixture.
I got a 6 inch authentic Arri fresnel lens. and mounted it in the screw in cap. The two pvc fittings fit together and slide easily together. So there is a nice flood, spot effect.
The led needs about 32 volts dc. I really wanted to be able to use it on some location work. I found a a voltage booster that take 12 volt dc and boosts it up to 32 volt dc. I had to put a heat sink and a fan to help keep it cool. straight 12 volt runs both fans. I also have a 110 volt led driver and a 110 volt ac to 12 volt dc to run the cooling fan. I mounted all of the electronics and the battery in the igloo lunch box and
found a 4 pin connector. I still need to put in a couple switches and do some tests but I’m feeling pretty good about the results
