I have 3 switches. 1 controls flood lights, 1 controls uplights & other one controls chandelier.
I recently bought 3 smart switches so that I can put them on timers all of them work fine except for the uplights. I have 5 of them and 2 of them are not as bright in fact they are very dim.
All switches are under one circuit breaker and I have only one neutral wire.
I know a little about electricity but I'm stuck on this one
Any help will be appreciated
It shouldn't be a wiring issue and only a matter of conflict resolution. Either the bulbs aren't dimmable AND/OR are LED's on a Standard Dimmer AND/OR that the Dimmer isn't Compatible or Capable of the wattage load AND/OR the one Dimmer's defective, of course.
If LED's, you need a Dimmer designed for the LEDs' low wattage. BUT, it must also be capable of handling the total wattage of all the LED's. Then, you have bulb brands that only work properly with certain and specific Dimmers...contact either or both manufacturers for their compatibility lists.
If not LED's, then your Standard Dimmer may just not be able to handle the load. Like, you may have a 250-watt Dimmer, but need 400-watts. Then, you'll need to exchange the 250-watt for a 600-watt Dimmer to get the lights working properly.
