It seems like energy usage depends on the dimmer setting.  At a full
500 watts it should use more energy than a 100 (or 150) watt bulb.
Unless it uses a hydrogen fuel-cell, of the type suppressed by the
U.S. Navy and large auto companies.

It may even use more, since you'd have to turn it up more, due to
the losses from indirect lighting (i.e. pointing it at the ceiling).
