I need a circuit for an outdoor lamp that utillizes a 13 watt flourescent tube with a two prong plug into a socket, a photo cell to turn the lamp on and off at night and a ballast transformer (the one I have which I suspect is malfunctionong is a Type 1. 753H for a 13 to 22 watt lamp made by Robertson Transformer Co. Cat No. SP2). The current circuit I have shows the transformer in series with the black lead to the socket. I have blown two of the bulbs with that circuit!!! Can anyone help me??? ny2850 email: rtgll@aol.com

 

My advice: buy a broken energy saving lamp, a cheap one and use the internal control gear (ballast). It is possible, that your transformer, if it is an electronic one, is broken and burns lamps. You can repair it, if you know how. Otherwise use the ballast I indicated. The hard thing is to adapt the sensor, because you have to attach it to the mains voltage, while the sensor should work on low voltage. Have fun and good luck!

Thanks for the reply. I'm fairly certain I can find a replacement ballast transformer. What I really need is a circuit diagram for the wiring of the bulb two pin socket, the three wire photo cell, and the two wire ballast transformer. I think I blow out bulbs because I have an incorrect connection in my circuit. If someone has such a circuit I would appreciate having a word copy or a schematic.
Thanks, ny2850
