A very tiny portion,negligible.I doubt you could measure it.

Not really. it's probably heated mainly by warm air from other parts of the
house.
Particularly since you say the lights are OFF when the room is vacant.

Does your bathroom have it's own thermostat?

Nonsense.

Sounds about standard,and how much traffic is on the roads doesn't matter
WRT the lighting of the roads at night.Road lighting is on at night
regardless of how much traffic.

Well,they source their own oil,there's no shipping,and they own their
refineries.
No taxes on it,either.
And they may generate their electric power from their refineries 'waste'
gasses that have to be burned off.Or from heavy oil products unprofitable
for shiping elsewhere.

They earn enough on petro exports to GIVE their citizens a stipend.
(just like Alaska does for it's citizens,BTW)

After doing a little research I believe you are correct. The motion
detectors use a triac as the switch and the filament is part of the
circuit.

I won't claim to understand it, but many motion detectors and timers
say "not for florescent" or "for incandescent lamps only" on them.
Some don't.

Fluorescents suffer wear from starting (unless they are the less
efficient, less common cold cathode type).

Compact fluorescents often start dim and take time to warm up.

Compact fluorescents not rated for use with dimmers can malfunction when
used with electronic switching devices not rated for fluorescents.

I do not recommend CFLs for motion sensor lights. Thankfully, as Paul
Eldridge noted, reflector incandescents are not affected by the upcoming
ban.

I use cfl floods in motion sensors, they all light so It is likely
your units design, I use X10 units. At 20f they take 2 minutes to get
full bright. 10f 3 minutes, 0 f, 5-6 mintues so they wont scare anyone
any you wont want it in your frige. They will get better but for now
in cold they take a long time to brighten. Popular mechanics magazine
did a review-test. In 4 years Leds might be alot better.
