MR16 halogen on dimmer to MR16 LED


I have 10 MR16 base 50watt halogen bulbs on a dimmer that I just replaced for 1.4W LED's (that supposedly equal 50 watt, but really don't). That's ok as long as I can get close to the brightness, doesn't have to be as bright. I thought this would work if I never used the dimmer. I even taped it in place so it wouldn't get accidentally moved, but I've already had one go out (and I didn't use the dimmer).

So I thought buying these would save me money, but at $29 p/ bulb, I'd say I've already lost more.

Does anyone know if the MR16 LED bulbs that are marketed as dimmable really work? I've found some at $59 p/ bulb, but Ö I'd hate to buy 10 of them and have more problems.

If not, can anyone recommend what it will take to put in LED's that work with a dimmer, or should I change out the dimmer? Or could you recommend a good place to buy the ones that do work?

Any info much appreciated.

Are these all(new and old bulbs) 120 volts or low voltage.

I would have replaced the dimmer with a switch before I tried them

The older halogen bulbs were going out after 6 years, 5 of the 10 were out. So I bought all new LED type bulbs, one is already out. The LED's are 12v AC/DC (reading off the box).

I'm currently looking for the box of the halogen type bulbs, cause I don't really know what the voltage is of my kitchen wiring.

How are you putting 12v bulbs into 120v sockets ?
Or were the halogens 12v too ?
Or did you put in new fixtures ?

I don't recall what the original halogens were, but I gave the box from them to the sales guy and he told me these would work. Though now I'm questioning what they are. I can't find the original box of the halogens so I really don't know what they are. I do know that these 12V bulbs are working, but ... they do seem a bit dim, I'm not sure how bright they are supposed to be.

Is there another way to find out what the electrical system is?

If they haven't all blown right away they are probably low voltage like the new ones. Two small pins on each lamp?
ou should find out whether dimmers are compatible with the LED's.

Yeah, there's two small pins on each, which in my understanding means the MR16 base.

And trying to find LED's that work w/ dimmers is what this thread is about.

MR-16's also come in a different base for 120 volts. Excuse me for trying to help.

No, don't take that wrong. Please do. Shows my ignorance w/ electrical. I was just restating my end goal because I was confused by your statement on finding dimmers compatible for LED's.

Most case the MR 16 bulbs the wattage and voltage will be stamped on either front glass or on the base or on the back shell one of three locations if you find them you can able run this number to us and we will be more than happy to translated the numbers for ya.

The MR16 bulbs can have either small bipins or GU16 sockets one of the two so that the other item you have to be carefull when you remove them.

Merci,Marc

LED bulbs are still being designed & tested
Many multi-LED bulbs are poorly designed & do not dissipate heat enough
Someone posted on another site that all 3 LED bulbs went out in a thunder/lightning storm
Not a single other electronic devoice was affected

I went with CFL's years ago & there simply isn't enough savings to change from a 9w CFL bulb to a 3w LED
Until the prices come down on LED's I'll stick with CFL
They do make CFL MR16's

I have LED hockey puck lights for under cabinet lights in the kitchen
I also bought 40 MR16 "bare" LED bulbs that each have 32 LED's & use ~2w
They were only $4 each & are 12.6v bulbs
I'm running them so far off a landscape light timer

LEDs do come in dimmable versions
How well they dim will differ by Mfg & design
