Electrical Wiring in the Home/replecing a florencent light on the ceiling


I am trying to replace a old florecent light with a new light. I got the old off the ceiling with no problems, we went to the store and chose a new light. The new light has two bulb sockets and has reach has a white wire and black wire and one has the ground. The old light was set up so that 2 different switches can turn in on and off and also had a red wire the new light does not. After i hooked up the black to black and white to white and the ground to the ground wire and did nothing with the red wire neither of the switches will operate the light. The light has power because the the bulbs light up, not sure if not having the red wire hooked up is the cause. If it is the cause where to i hook the red wire to since there is not a red wire in the new light? Thank you for your time.


Three Way Circuit
Three Way Circuit  
Your set up is called a 3-way light circuit.

Here is drawing of the three different ways to wire this type of circuit.

It mostly depends on where the power comes into the circuit.

Yours should match one of the drawings.

(the drawing shows an incandescent bulb but it works the same for florescent)
