Dimmers for Kitchen? Humming prob?

maruhaMay 22, 2011

I am planning on having 4 recessed cans, 2 pendants over the island, undercabinet lights and one over sink light (not sure yet if can or fixture.)

I'd really like everything to be on dimmers, but my GC says there can be problems with humming. I have heard that if you have the right dimmer for the type of light, it's not a problem.

I'd like to have all of the lights controlled at one or two main locations, but do I need to have different kinds of dimmers for each kind of light? Advice on the best type of lights to use so that this coordinates somewhat simply?

Thank you!

Here's my floor plan:

Incandescent dimmers cannot be used with CFLs or low voltage lighting. Those will need to be matched with the lighting requirements.

Most LED lights can be used with incandescent dimmers but tend to be pricier than CFLs.

Steer away from rehostatic dimmers as they will dissipate quite a bit of energy as heat.

Your GC should have an electrician on staff to figure out things.

Electronic low voltage diva and maestro dimmers from Lutron that use the neutral will not hum or flash on any dimmable cfl's or LED's or low voltage halogen lights. Get these dimmers and you won't have any issues.

"Incandescent dimmers cannot be used with CFLs or low voltage lighting."

Not true for many low voltage lights.
If you use low voltage lighting that has 'electronic' transoceanic many of them will operable from a conventional Triac dimmer just fine.

It is very hard (even with deeming ballasts) to operate discharge lighting (and florescent is discharge lighting) at ANY setting except full on.

"Those will need to be matched with the lighting requirements."

You need to look at the manufacture's recommendations.

"Steer away from rehostatic dimmers as they will dissipate quite a bit of energy as heat."

No one has used rheostats for deeming in a LONG time.
There power dissipation approaches the power dissipation of the light at low settings.
Even stage equipment switched to autotransformers many years ago (and now is mostly electronic Triac).
