The Grimes cockpit map light I bought is wired to the 12VDC buss only for convenience as I didn't have a 28VDC bulb to wire it to the 24VDC buss.
My question is, because of the resistance of the rheostat used for the dimmer, is this causing the lamp to be dimmer on 12VDC than it would be on 24VDC? Seems to me it would.
The lamp works fine, but I don't think it's as bright as it should be even when turned all the way up. I'm wondering if the rheostat has a higher resistance than would be required for a 12 volt circuit.
