Electrical Wiring in the Home/Mixing Bulbs in Recessed Cans


QUESTION: I have 6 recessed lights in my living room ceiling and the cans take BR40 bulbs. At the present time I have 6 halogen incandescent dimmable bulbs in the cans and the first bulb blew after about 5 years. I have not yet replaced it and I expect that the others will go shortly. I would like to eventually replace all the living room bulbs with BR40 dimmable LED bulbs, but not all at once because the cost of these bulbs is still quite expensive (about $30 each). My questions is: Can I mix incandescent and LED bulbs on the same circuit, or must it be all incandescent or all LED? Thank you.

ANSWER: Yes, you can mix them.

QUESTION: I now use a dimmer for all 6 incandescent bulbs. If I replace a couple of them with LED bulbs, making it 4 incandescents and 2 LED's, can I use the same dimmer? I heard that I might need a dimmer made especially for LED bulbs. Thanks.

Usually the LED lights are made so that they are compatible with a standard dimmer.  I have one dimmer where I have used LED, incandescent and dimmable CFL bulbs. If the LED bulbs say they are dimmable, it would be with a standard dimmer, unless it says otherwise.
