I have a 70 watt HPSV light fixture, can I temp install a 50 watt bulb? The 70 watt bulb is bad and only 50 watt bulbs are available locally. Thanks
"Temp"? For how long?
A few days will not hurt anything. Long term will be bad for both the ballast and the lamp.
Please post back and let us know how it turns out....
Thanks for answering, the wrong bulb would be used for less than a week.
