The shot could not have been easier. The panel LED lights we used were the Bescor LED-70 Dimmable 70W video lights. I chose them because they were small and powerful enough, but were also dimmable making it easy to balance their light output with ambient light. They also take AA batteries instead of a rechargeable cell. We don't use lights like these too often and I didn't want to have them sitting around with a battery cell draining away. With the double A's I can simply pop in batteries whenever we need to use the units. Rechargeables would probably have resulted in a smaller unit, but the dependability of using AA's out-weighed that for me.
The lights were powerful enough to allow me to work them at full output with an exposure of 1/500 second and f/1.4 with an ISO of 400 -- more than sufficient for my needs. Bescor also makes a smaller 40w unit for $24.95 using AAA batteries. It it isn't dimmable but could always be used with a neutral density filter gel taped over its face.
