always face the bearing North when light bulb heating to make sure it
alligns with North magnetic pole, allowing for deviation and compensation.

But don't forget to spin it on the bulb after heating to de-magnatize
it - otherwise you may attract contaminates and they'll be sucked in
as it cools. :-)
