Wow!  What can I say about Vision Engineering's LED lights... I recently acquired a small panel for use in video production.  The simple, cool daylight balance LED panel saves me time and energy when setting up lights for interviews and product demonstrations.  Before these panels, I would have to wait 15-20 minutes before I could pack up my traditional lights because of the high temperatures, now all I have to do, is turn them off and pack them up... quick and simple.  I can't wait to purchase my next set.
