Default Xenon to LED UC lights

One of my relatives has 12.8V 18W Xenon under cabinet lights. The lamps keep burning out and they hate having to change them.

There are a lot of lights under many different odd sized cabinets, and the romex feeds come out of the wall into a little junction boxes where proprietary cables exit and go to the lights. So installing brand new UC lights would be a pain.

I have never dealt with Xenon UC lights at all, I went straight from fluorescent to LED. So I am curious if there is any way to retrofit LED lamps into these Xenon lights?

There are bi pin LED lamps designed to retrofit them. I'm not sure how good they are, but they are available. Search the internet for say G4 base LED. I haven't found local supply houses to be very good on this one. 1000bulbs has them.

Are the lamps the wedge base T5 style also used in some landscape light fixtures?

If so, check these out...

Likely less expensive than installing new LED fixtures or constantly replacing Xenon lamps. However, the 3000K color temp may appear a bit different compared to the existing Xenon depending on the backsplash and countertops.

Slightly longer than most Xenon T5 lamps so might not fit all fixtures.

You can try the led retrofits, but you won't be happy with them. They will fllcker from the lack of a proper full wave rectifier and the cheap electronic transformers in quite a few low voltage lights have a minimum wattage to operate which the LED replacements don't meet. Tear them out and replace them with LED fixtures. I have had really good luck with these. Both big box stores carry the same ones

They dim like butter. Stay away from the orange store brand ones. They install weird and the different size ones dim at different brightnesses.
I know you want a quick easy upgrade, but you and your relative will be disappointed with the retrofit lamps. You have my permission this time only to use lever nuts to save time on this job

Changing fixtures would be one thing, but relatives not of the mom variety, can change their own dam lamps.


I put direct replacement T5 wedge base LED lamps (from Amazon) in my mother's Xenon fixtures about 2 or 3 years ago. A few have already failed, but that's still good compared to the crappy Xenon's themselves.


Hopefully it was just a 1st gen thing and the new ones will last longer. They'll be there waiting for me on Saturday as she ordered them herself this time.

So they tried the LED replacement lamps that Summit linked to above. They flash. They also seem a bit loose in the socket, I was told.

But they did not flash when one normal Xenon lamp was in the light. Could that be because the LED's alone are not meeting the tranny's minimum load?

I am not replacing these lights so its either find LEDs that will work or they keep changing the Xenons monthly forever.

This one’s easy. The smart thing is to replace the fixtures. If they want to keep gluing the old crap together, not your problem.

Xenon is evil. My final job with xenon, they were so hot they melted an expensive coffee machine. I had a fixture left over and it went in the dumpster.

Let me try this for the 3rd time: I AM NOT REPLACING THE LIGHTS!

Read the last line of the post I made that you quoted.

Either. I am not replacing anything, it's a 3 hour drive and I don't want to do the work to replace all of those lights, it's a giant kitchen along with a desk area and wet bar.

I just want to help them find an LED bulb that will work so that they don't have to change the bulbs as often.

If this comes up on a real job, I have installed this driver under the counter. I see Home Creepo in the US sells it (horribly overpriced though; I pay half that in loonies).
