Its been a while but i have just finished protoypes of lights
They are 110Vac or 220Vac, dimmable and output is 900-1200 Lumen This is fixed due to the avliablity of acriche LED ( quite a challenge to find )
However if you wanted to go from 9-36VDC you can get 2500 Lumen with HD light it seams every one likes HD light 6500K 🙂 must be the new buzz word
The costs are varaible but components are i the 100USD reange for LEDs and drivers the main issue is the water proof case hence why i thin retro fit would work as you can fit to any shape
