Thanks. And thanks for the link: I've actually got several of these cans so may order multiples in any case.

Those are available at my local hardware store, both halogen and LED.

Maybe but one has to be careful. Most MR16 120 volt LEDs have a GU10 base and most MR16 LEDs with a G5.3 (pin) base are 12 volt.

Thanks for the reminder - I have both types in my home!

wdccruise- I agree: I had to wade through a lot of listings when I was initially looking to get the correct combo of pin type, voltage, and wattage.

MR16 is a wider prong placement, so it should be easy to tell, that being said looking at the pin spacing on that bulb, its a 12v bulb. and then i googled the can item number

JUNO IC44N 4" IC HOUSING 12V 50VA, if you also read the housing it says 12v .... i can tell by the pins on the MR16 that is a 12v bulb!!

RL Relocation- Thanks....I saw the 120V primary language on the label and somehow missed the bit about the 12V secondary. And apparently you're the only one who looked past my initial misstatement about the voltage and analyzed the label in the housing correctly. That explains why the 120V replacement bulbs I got yesterday didn't light up 😂.

yes, you are lucky enough to still have a clear label in your can!! but also the pin spacing on that mr16 and also the actual prong thickness told me it was 12v. mr16 120v have thinner prongs as well, thus they will bend and fit into a 12v socket lol. 12v mr16 led will probably have more options for dimmable aswell. happy to help!
