Wiring diagram

I have a problem with this configuration and can't figure it out on my own.

Configurations I've tried:

1: Bulb1 and Bulb2 white and black wires connected to light switch black and white wires. Copper wire connected to junction. I Turn power on, turn switch on, no light.

2: Bulb1 and Bulb2 white and black wires connected to breaker white and black wires. Copper wire connected to junction. Turn on power, lights come on, but switch has no control.

Note: I have tested continuity on the switch, and its wires. There is no problem with the switch. Also the light fixture is brand new. And the light bulbs are tested working fine.

Correct config

This picture above really simplified things. (took it from another thread)

The easy answer is "Hook it up just like the previous light was hooked up", but I'm assuming that you didn't keep track of the original configuration.

To make it work again, connect both of the lamp white wires to the white wire coming from the circuit breaker panel.

Then connect the black wire from the panel to the black wire leading to the switch.

Then connect the white wire from the switch to both black wires of the lamp.

Then, make sure you mark both ends of that white wire with black (tape, pen, paint, etc) to show that it's a switched hot so someone doesn't confuse it with a neutral some day.
