Bus riding back from work, I have noticed a 4X4 with a (30"?) bar of led... If one plugs one of these bars in a 12v converter, could it be a (more or less) cheap way of getting a flood for a home made studio?!
These led bars come in all shapes and lenght (led and HID). And they throw light... maybe to much! Eventually, some sort of diffuser could be set in front to get a more diffuse light.
Depending on the company, they range from 5000k to 7 500K. One would need a filter to get 5400k.
Anyway... just an idea that I want to confront.
Here are a few links of makers:
