Here is just a quick little video I shot to play around with some cheap $6 led lights you can buy from Pier One imports.
Overall I am really impressed with the quality they give. The one thing I did notice is that they are very inconsistent with the colour, one comes out yellow, while the other comes out green. All you would need to do is gel them and it would even out. This is a great solution for shooting somewhere that you don’t have access to power. These run on triple a batteries.
