Photocell controlled light

[ke4vbg]

Hello

I have a light on my garage that I connected a photocell to so it would work from dawn to dusk. The photocell is one off of a mercury vapor light fixture. The light operates fine. I use a 100w incandescent bulb in it. My problem is that the bulb will only last about 3 weeks before it shoots. I have tried different wattage bulbs with the same results. I cannot figure what is causing such a short bulb life. Any thoughts would be appreciated.


Thanks
Doug
