HPS bulb is dim
I just replaced a 70 watt LU70 bulb in my driveway and it won't get bright.. It only stays dim. It comes on and off correctly but doesn't get that bright orange glow. Any ideas?
The old bulb was cycling on and off, barely even getting full brightness before shutting off and starting over. I let it go until it was out completely. Bad choice I'm sure. Any idea if I just have a bad bulb or is there something more wrong with fixture like capacitor? |

If you let a low pressure sodium lamp operate ANY length of time with a bad bulb you WILL destroy the ballast. My guess is your ballast is TOAST +1 The ballast is the place to look. |
