I got a couple Philips Halogen PAR38 72w flood lights and tested them on a Flukers 8.5" 150w max dimmable dome. The fixture states not to use a light higher than 75w with the dimmer function, so these bulbs are compatible with the fixture. They work fine, no flickering or anything. But I noticed they make a very quiet humming or ringing sound when dimmed that isn't present when the bulb is receiving full power.
Tl;dr - halogen bulbs make quiet humming/ringing sound when dimmed.
Is this normal or should I be concerned? Is it harmful to a bearded dragons hearing?
