We just investigation the options for our Cessna T210, and decided on
the halogen relplacements. We were going through the old incadescents
at about 1 per every 10 landings, and at $23 per light, it was getting
to be a pain in the butt. Not to mention the disappointment of needing
the light and finding out it burned out on the last landing.

For $550 apiece, the HID lamps were just not worth it, so we went with
the middle ground; about $40 apiece for the halogens, and so far so
good on both the ligh intensity and durablilty (although they've only
been in about 3 weeks).
