LED and single switch for ceiling and under-cabinet lights

11 years ago

Hi. I have a single wall switch in my kitchen which currently turns on the incandescent ceiling light as well as under the cabinet florescent lights in each of ten wall cabs (if on). Since incandescent is slowly being fazed out, I am considering replacing these with an LED ceiling mount fixture and LED under-cabinet lights.

My question is, in my kitchen remodel (not to studs, more a pull and place with ample wall outlets and switches between the kitchen and pantry) may I use the same single wall switch for the both ceiling and under-cabinet LED's? If yes, where does the dimmer switch go? On a second switch? Is there a transformer box that sits somewhere (I've heard in a sink cab) that controls the LED dimming?

There are some lovely broad spectrum LED ceiling light fixtures (800+ lumens or is it diodes) which I believe work well for us. I have two 200 amp panels with openings.

Thank you very much for your help.

If you intend to use low voltage for the UCL, 2 separate switches are essential.

If you use direct wire, 1 switch (dimmer possible) may be possible. There will not be a separate transformer box.

davidtay, thank you. I've read your LED discussion.

What do you think of a broad spectrum LED ceiling fixture or pendant? The fixtures are not that expensive, but I understand the bulbs are. If I put them in each center ceiling parallel ceiling fixtures, there will be bright light: enough with the LED uc's to avoid recessed lights? I currently do not have recessed lights, as I dislike swiss cheese holes in a ceiling immensely.

You can't hide the transformer in a wall, it is a code violation. Do you have a basement underneath the kitchen? My electrician installed the transformer for my in-cabinet lights on the basement ceiling. For under cabinet lights, I have Xenon direct wire lights that are connected to a dimming wall switch. They don't require a transformer.

" The installation instructions show the right one (altho I don't see any reason not to just use a regular outlet box with a plate)." If you do not want blank plates scattered around for junction boxes you can also use the kitchen counter receptacle boxes a junction boxes fro wiring the under cabinet lighting. Watch carefully for box fill, and you might even have to use 4 inch square boxes and a plaster ring for some of the counter receptacles to get a large enough box. Since the runs to the under cabinet lights are all 120 V, all the regular NEC rules apply, but having different circuits share a junction box is allowed.

What is being referred to as "Xenon" here is really incandescent bulbs. Smaller incandescent bulbs (like the type found in old-style flashlights for example) have a much lower color temperature, and as a consequence the light typically feels very orange-colored and dull. Bulb designs filled with Xenon gas help compensate for this, to some extent. I can get much more into the technical details if you want, but that is the basics of it. In general though, Xenon will still give off a lower color temperature than halogen, so if you really want a brighter whiter color of light, Xenon is probably not the best option. LED is probably the best option for undercabinet lighting, but can oftentimes be overly pricey. If color rendering is an important consideration, you might want to look into high CRI LED lighting, because under regular LED lighting colors can appear just a little grey-washed or yellowish. This is likely to be even more pricey though. Incandescent bulbs (which includes Xenon and halogen) are just not particularly well suited to undercabinet strip lighting. For one thing, when there are multiple bulbs each with a lower wattage, the color of light is confined to the very warm white color territory. Then there are always bulbs burning out that need to be replaced. There are many different options, and they all carry their own subtle advantages and trade-offs. All undercabinet lighting is kind of overpriced, in my opinion, so unless you are really looking to create a dream kitchen, you might want to consider going without it.

I've never had a client complain that their undercab lights were too bright - go 400 to 500 or higher, but look for a dimmable system so you can turn them down for a dinner party. And be careful with the brand you select. If you go with the cheap ones from Amazon, they produce a green tint to the light. A better brad like WAC has a much whiter light, a better cri, and a lower failure rate. Tresco is another brand - they offer the widest variety in selection, color, lumens, and mounting options. As you plan the system, make sure you can get to everything and replace components if needed. The transformers are the first thing to go, but the leds do have a failure rate as well.

Further comment on controls
For purposes of flexibility, you might want to have 2 switches (both can be dimmable) - one controlling the lights and the other the UCL. That way, you can have either the UCL alone or main lighting alone or both on.

Broad spectrum LED fixture or pendant
Ceiling fixtures work best with galley kitchens as the counter spaces will not be too distant.

Broad spectrum lighting is a simulation of real sunlight (as it appears to the human eye). Most LED lighting will not come close to being really broad spectrum.

If you're planning on using something like the L prize bulb, you will have very efficient but not really broad spectrum light. Otherwise, you'd be using lighting with a higher color temp (3500K - 5000K).

Recessed light comment
The swiss cheese symptom becomes very noticeable when the lights are not placed in a regular pattern and if the holes are of different sizes (eg - mix of 4", 6").

The downside to recessed lighting is that it can more complicated in terms of planning than typical surface mounts since more are typically used vs 1 central mount.

However, it is always worth spending the effort planning proper lighting, even if you ultimately don't use recessed lighting.

Thanks again, davidtay. I am beginning a formal lighting plan for the kitchen remodel and will have professional electricians and lighting designer input as this is not my forte, yet key decision.
