We replaced a fan that required the three wires, white, black and red with one that is controlled by a remote and only uses the white and black wires. My question…since there’s a light switch that used to control the light can I use the red wire and switch to control 4 can (pot) LED lights? Thanks for the information.

  • Be careful not to put the can lights too close to the fan. The pitfall is moving as shadows when both fan and lights are on. – Tyson Jun 23 '16 at 21:14
  • Yes there is a switch to it. How do I wire the cans? The ones I have, have the white, black and ground...how do I hook just one wire? – GE-Minigun Jun 23 '16 at 21:41

    If you want more advice about making sure you haven't double-stuffed the box, turn the power off at the panel and post a photo of the innards of the box in your question. – ThreePhaseEel Jun 23 '16 at 22:27

You'll run a /2 cable to the fan-box from the can-lights and connect bare to the rest of the bares, white to the rest of the whites, and black on the new cable to the existing red wire -- wire-nuts or Wagos are available at any big-box or hardware store. Just watch your box fill and make sure you aren't overstuffing the junction box -- you may need a round/octagon volume marked mud ring to add a few extra cubic inches with the additional cable/clamp installed.

And yes, don't put the can lights where the fan blades can block them, otherwise you'll get annoying shadows when both are on.

If the light can handle 120V, sure. Be aware that the red wire is usually used with a switch.
