I replaced the lamps with GE's Genura, which is a 23W
electrodeless compact fluorescent.

I've heard of these, but realise I don't know how they work. Does
"electrodeless" imply RF-excited, like the Philips QL system, or something
else completely? The 20,000 hr lifetime you quote is much less than for the
Philips, so perhaps the latter...?
