Can you use different, lower foot candle bulbs?
Talk to your electrician. Maybe he/she has an idea.

LED lights are still very new in the commercial/residential markets. Like their fluorescent predecessors used to be, the color rendition in LEDs is still very limited and, as you've noticed, take some adjustment.
There is nothing you can do until the LED manufacturers develop LEDs in a broader range of Kelvin. Of course this will affect the color of everything they illuminate- which is why your wall color has the greenish cast it does. These are the trial-and-error experiences DIYers go through. Very few people outside ALA certified ighting specialists (like myself) would know to advise a client on.
I suggest focusing on the cost-saving benefits the lights will gie you for years and years to come. Eventually- and much sooner than you think- you will get used to the light color and quality.

i must have the same dimmer in my bathroom because when i'm soaking in my tub, with lights dimmed to 25%, i hear constant buzzing too!!!!!!!!!! yikes. wish i had better news for you!

as for your pictures, they look ok to me but it's hard to tell unless you see it in person....

are these creLEDs?

If I'm reading your plans right (1 square = 1 foot?), you have 7 cans over about a 9'x5' floor area.

Yes, that's way, way, way too much light.

I would take them all out and put in a decorative fixture in the center of the room. If your pendant lights don't light up the sink and counters next to the sink well enough, move the two cans flanking the sink area back so that they are over the midline of the counter, and use them to light the counter and sink.

I have 8' ceilings too with about the same spacing of cans. I only use them when I'm doing a lot of work in the kitchen. And as soon as I'm done they get turned off. Even though they're dimmable I see it as a waste of energy. I keep my undercabinet fluourscents on all day ... only turning off overnight. And the pendants over the peninsula are used as needed, but I do utilize the dimming feature with them.

If they will take the bulbs back, I would exchange them. The buzzing would drive me crazy!!! I tend to get migraine headaches, and the fluorescent lights in my bank will bring on a headache within minutes- I couldn't work there for love or money.

So, not having LED's, am I understanding correctly, that it's just the bulbs, and you could put some other kind of bulb in your housing? I would do that for now, and convert to LED's when they improve.

Once you're using the kitchen again your perception will most likely change. Right now they're new. Give it time.

Yes, these are the Cree LED lights. They seem to have received rave reviews, so I was under the impression that these were the first LED lights to really be a viable option. It's true that they are much better than any other LED lights I've ever seen -- they definitely emit a lot of light and they don't have any of that blue-ish hue that I usually associate with LEDs.

BUT, I really don't like the light. In fact they make me feel a little carsick, particularly at any level of dimming the resulting strobe effect literally makes me feel ill. So I will have to return them and find another solution. It's very disappointing.

I should be able to just put some other kind of bulb in the housing. I'm not sure what kind to get though. I'm also not sure whether to just do the minimum fix (ie switch to other bulbs), or to take it a step further and reduce the number of lights ... which would also require moving the remaining lights. And if I do that, then should I also switch to 4'' housing? And if I do that, should I switch to low-voltage? Or am I now just driving myself crazy and should just probably try switching out the bulbs first.

If I assume I'm just going to switch to other bulbs - what kind should I get?

To find out what you like, experiment! The easiest way to do that is to try lamps that will fit in housing. I suspect it takes normal Edison base lamps, so you can try lots of different things. In general, though, "lots of different things" pretty much comes down to standard "A" lamps of various wattages, and various reflectorized lamps, of assorted beam widths and wattages. What you probably can't do with what is currently there is point the lamps anywhere other than straight down, or move the fixtures.

Play around, and have fun!

I felt exactly like you do with my last kit. They had all of them on one switch. I had the electrician come back and make 3 swithches. The one I used most often on one (prep area) two flanking range on one and the rest on the third. Two and 3 switch were on dimmers. I can honestly say I never in 5 yrs used the 3rd switch.

I have the LR6s as well, 9 of them in a 12 and 1/2 by 25 foot space (plus a different kind of recessed LED over the sink). I love them, and others who have seen them are very impressed. Have only had them a few weeks, but they are the first to go on, at full power, and stay on when we're in the kitchen. First thing I would do is make sure you have the right trim kit and dimmer switches - many can be used with these, but not all. Second -- are several connected to one dimmer? When mine were first installed, we only had 3 on one switch because I had bought too few by mistake, and it wasn't enough for them to work properly (need at least 4). One of the lights would flicker. Now there is no problem. LEDs should NOT buzz or flicker.

Good luck.

I'm glad to hear that the LED lights are working for you. It sounds like you have a much bigger space than we do, with only 2 more lights. I think this was perhaps our biggest mistake -- just too many of these lights. (As I mentioned, I was worried that LEDs wouldn't put out enough light). Maybe if we had only installed 4 of them, the amount of light would be ok. To reduce the number to 4 at this point would require completely re-placing the lights and rewiring.

I wonder also if the increased number of lights in our smaller space is amplifying the effect of the flickering? i.e. maybe it wouldn't be noticeable if the lights were further apart?

The housing and dimmer switch we have are both on the compatible list on the Cree website. All 7 of the lights are connected to the same dimmer switch. So I'm not sure what the problem is.

When they are on at full power, they don't buzz or flicker. We had friends over yesterday and at full power they thought the lights looked great. (It wasn't too bright for them). Then I dimmed them and they didn't think the buzzing was too bad. They also didn't really notice much flickering. But then I started waving my arms around and they were shocked. The strobe effect when the lights were dimmed made my kitchen seem like a disco!

Cbjmidwood, when you dim your lights and wave your arms around, is there any strobing?

My husband suspects your issue with the flickering/buzzing is related to the dimmer and not the lights. What specific dimmer are you using? He said he will look up the dimmer information and try to help if you can provide that information.

The dimmer is a Leviton Illumatech IPI06-1L.

Thanks!

Oh Aussies, this is breaking my heart! I have watched your research on the board and have decided on the LR6's, too. My kitchen is a tiny bit bigger and I have only five going in. They'll be on three switches....yes, dimmers. I am super-sensitive to buzzing, so I am worried. OTOH, I am getting older and find I need LOTS of light to work comfortably. Please keep us posted!

aussies -- I tried the arm waving and didn't get any strobe effect. The dimming is a bit uneven, e.g., some of the lights go off before others. Not a problem for us as I'm not sure we'll really use the dimmers much.

amysrq -- You might want to check with electrician... I'm not sure 5 LR6's on 3 switches will work. Each dimmer switch needs a minimum amount of wattage which I believe equates to about 4 LR6's (since they're so darn efficient!).

Oh, well, that's just grand, isn't it? I hate it when we push the technology envelope and force new tricks on old dogs who don't even know what the hoops are...

I'll speak with the electrician asap. Thanks.
