Internal light kit for all sizes of tubular skylights. Great item for replacing a bathroom or kitchen light. Install an energy efficient LED bulb and use the same switch for the kitchen light.
Installation is simple: once the light pipe is installed, make a small hole in the side of the pipe and with the hardware that's included, adjust the fixture so it's in the center of the tube about 18" above the ceiling trim ring.
Connect the old light fixture wires to the light kit and secure with a junction box which is included as well. It's simple wiring but if you are not confident about doing it by all means find someone experienced that can help you.
The low price is only if the light kit is shipped with a tubular skylight order.
