LEDs are moderately efficient; the average commercial SSL currently outputs 32 lumens per watt (lm/W), and new technologies promise to deliver up to 80 lm/W.
From halogen to LED you can divide by 4 to find the equivalent. Therefore an 80 watt LED would do the job.
If the exit fixture uses a LED lamp it will have a 1 to 3 watt rating. If it is a incandescent bulb, each lamp will draw about 25 watts each.
1 KW = 1000 Watts.......1 mW = .001 Watt.......1 microwatt or uW = .000001 Watt
1 watt-hour equals 1 watt times 1 hour, or 3600 joules.
A 13 watt CFL bulb is roughly equivalent to an 8 watt LED bulb in terms of light output. Look for an LED bulb with around 8-9 watts and a lumens (brightness) output of approximately 800-900 lm to match the brightness of a 13 watt CFL bulb.
The maximum lumens that a 1-watt LED flashlight can have now is 160.

There are 1/.1 = 10, .1 watts in 1 watt.
Typically power leds operate as 1-2 watt units. 50 watt is a little excessive for a single led: it would have to be an array. The light output that can be achieved in normal use appears to range from 80-120 lumen/watt, so I guess the answer would be something like 4000-6000 lumen!
