yes, after extensice research I found that switching to LED was best choice with or without added expense of solar. also, no need to replace fixtures, this website that I found has almost every application of LED direct replacement available and the most resonable cost. link to website is here www.mygreenpros.com I replaced all my yard lights with combination of SMD chips, MR11, MR16 and some Disc. leds and so far I am on month 22 with no problems. very reliable LED's and good customer servivce too. I triled Ebay but found a lot of issues. this this website a try, they take it back if you are not satisfied. good luck! This post was edited by behlgarden on Tue, Apr 8, 14 at 14:01

To answer the question, we remodeled a few years ago and I did all Halo 6" cans in the kitchen, but fit them with a Cree CR6 LED trim. It seemed the most cost effective at the time and the most flexible going forward. I did not want to get stuck with a weird bulb base that I couldn't adapt to in the future. All retrofit stuff seems to have an edison (the screw type) base available. But if all goes well, those Crees will last well into the 2030's, so I don't have to worry about it. They look great, though and despite the fact that they could have 75W each, my inspector gave me a pass for using LED lights so the circuit is nowhere close to capacity. Best of luck. Anthony

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.

Funny, I just went through the buzzing problem with Leviton. I have very acute hearing and could hear the buzzing when the GE under cabinet lights were on even though the electrician couldn't, but he could hear it when he put his ear up to the dimmer. I bought a few Soraa bulbs to try and the buzzing was ridiculously loud with the Leviton (fortunately was able to return the bulbs), too. Anyway, finally got around to changing the dimmers out, and the Lutron Divas didn't eliminate the buzzing, I ended up with Legrand Radiant, which do cause the very faintest of buzzing but I can't hear it unless the lights are dimmed all the way down, so a non-issue because I'm not in there if the lights are dimmed. They didn't make the bulbs in the overhead cans buzz either. It's frustrating because what dimmer may work with one electrical component may not work with another.
