LED Tubes

Amazing new technology that gives the filmmaker endless possibilities with Tube length sources with color temps from 2000K to 10,000K..  They give you the ability to create lighting effects, match gel colors, dim down to .1.  You can put them into a dimmer board to control everything or on an iPhone or Android app. They are lightweight and can be powered by an internal battery which opens up huge options.  I use them for eye lights, background bokeh, ring perimeters of buildings, etc.
