[Novalug] This is waaaaaaYYYYY COOOOLLLL

[Ed James]

Tried the same calculations.  50 pounds at a height of 4 feet has
200 ft-pounds of potential energy.  1 joule = 0.73756 ft-lb, so
we're talking 271 joules of energy.

1 Watt of power is one J/sec.  There are 14400 seconds in 4 hours,
so 271 J released over that time means about 0.02 Watts.  Those
must be darn efficient LED's in that gadget.

I realize that the 40 watt number refers to power needed for comparable
light from an incandescent bulb, but still...
