fluorescent lights
Are 12v and 120v tubes the same? Tubes in overhead lights last only 3 mo.
Forum Discussion
Yes the same tubes
How ever the electronic circuit board ballast, is designed to work with even low battery voltage.. aka 11v
So if parked on shore power 13+v driving the ballast , the tubes might be getting hit with higher than avg voltages
Also they do suffer from getting too hot
Mine would last one or two years
I finally went LED because of the cost of replacement tubes, not because of power use
