If you don't use the transformer, will these accept 12 V DC input? Are they dimmable?

sorry , canot . the ceiling is 85v-220v light .canot accept DC12V input . thanks

These are 12V (probably AC only) If you will have transformer to 12V they will work technically. If you have an isntallation with multiple MR16s and you would like to change it to LED I would recommend to change the transformer to LED version. Otherwise it may not work or if it will work you will decrese the lifespan of the bulb (I work for LED manuacturing company in EU)

These are direct replacements for incandescent. No transformer required. Note: these DO NOT dim.

My lighting designer told me that it would not work with low voltage transformers. They suggested the Lutron Diva for that purpose, which is what I am using. I used these everywhere else in my house, though, and they work well. They're a little strange to wire, especially in 3-way and 4-way applications, so you need to have the wiring instructions handy when you're installing them. We also did use these with LED bulbs, and the dimming works funky with dimmable Cree LEDs. One light fixture had two Cree dimmable LED bulbs in it, and the light would not come on when set to a dimming position, when when "turned up" it would flash one of the bulbs on, and then finally the other one. We did not experience this problem with TCP LED halogen replacements, only with Cree standard dimmable LEDs.

No they are designed for 115v ac. If energized @ 12vdc I would expect no discernable light ourput

i don't know. I put these bulbs into standard 110V fixtures wired with 24VAC low voltage landscape lighting. I didn't try using a dimmer.

These lights definitely work fine with 12VDC, and that's what I'd recommend. However, they also have a bridge rectifier built-in, so the DC polarity you supply doesn't matter, and I'd guess they will work with AC as well, although it's possible you'd get some 50/60hz flicker in the light output, and perhaps create more stress on the electronics depending upon how well the built-in regulator handles it.

You need a 12v transformer. Mine are direct wired transformers that I have up to four lights wired to.

these are 12v dc and you can also run (but not dim them) on 12v AC. At 1/2inch the tube is pretty big.

The ones we bought are 12v. They plug into a socket/fixture that is wired to 120v but I believe the fixture has a step-down transformer. They have worked well for us.

Since these are 12V LEDs, they require a separate 12V power supply and I suspect that the 12V power supply would not handle being on a dimmer circuit. There is a low cost dimmer available, see http://www.amazon.com/Lighting-EVER-Dimmer-Wireless-Control/dp/B004X4O1NG/ref=pd_sim_hg_4

No, requires a transformer. I connected mine to a power station that controls my lighting.

Not if they are DC strip lights. The unit is AC input and output. Even though it does not state on this page what the output is, I've ordered one. It is AC output and will NOT work with DC lights (at least without flicker). I'm not an electrician, but DC lights strips should have an AC to DC transformer.

Nope, you will need a 120ac/12vdc power supply for these lights. These are light emitting DIODES, so you must observe the proper polarity when you are hooking them up.

Mine are super bright, but with what's included in the box, no.However, any light can be dimmable. LED's use DC current, these particular ones plug into standard 110v, then have a mini transformer to switch it to 12v DC. The "dimming" has to happen after that transformer where any full-range switch would work.If you search "LED rope light dimmer" on Amazon, there are interchangeable power cords that DO have dimmers on them that work with this product, but they will ONLY handle ONE 50' run.

I don't think so. The transformer needs full power from your wall socket. You would insert a 12 volt dimmer between this device and your string of lights.
