Waked up early in the morning today and finally started some quick machinings ... took couple of hours and now - here it is - 50W LED lighter with integrated cooler and integrated power supply.
OD 69mm, L-205mm, there is 33V LED-driver inside - thats because its so long, as well as PC cooler and small DC/DC converter for. End cap on the back I will mill out later ... too bored today
Yeah - now it really does not go hot - forepart ca 35C degrees.
I bought special 62mm reflector and lens exact for this LED, via eBay from Taiwan.
Yes, it is bright ... even very bright, but is it better than 50W...60W Halogen or Xenon bulbs? Im not sure. At least there you do not need the cooler and extra driver ... and costs much less.
Looks like I built the most stupid lighter in the world
I have one 30W and few 20W LED but I dont want to build such kind monstrum anymore
