    Dim LED MR16 Lamp to 1%

    Dose any of the Lutron dimmer can dim LED MR16 lamp to 1%? Or how low can it possibly be dimmed down to? I've asked Philips, Soraa and Green Creative. I found out the LED lamp can be dimmed to 10% mostly and it depends on the dimmer not the LED lamp itself to dim to lower light output.

    Soraa: SM16-07-25D-830-03
    Green Creative: 7.5MR16G4DIM/840NF25
    Philips: 7MR16/F25 3000 or 8.5MRX16/F25 3000

    Please help me find out if any Lutron dimmer can dim any of these listed MR16 LED to hopfully 1% (or as low as possible).

    Good morning Zheng,

    A big issue with LEDs is that they are all being manufactured differently, and so the dimming performance will vary greatly from one to the next. Many LEDs on the market (including ones labeled as dimmable) have issues when placed on dimming controls. On top of that, MR16 LEDs are generally one of the toughest types of LED to dim. The issue with these lamps is due to the interdependencies between the lamp, transformer and dimmer. Only certain transformers work OK on a given LED MR16 and even then, only certain dimmers will work, and even then the MR16 lamps generally have some shimmer as you dim down.

    Because of this, Lutron has done extensive testing on LEDs, however we only have a dimming solution for a few different MR16s. Because of the sensitivity of LEDs, we can only recommend for ELV transformers that they are used with the Lightech LET60LW transformer or Hatch RS12-60M-LED and only one lamp per transformer. If you go to and change the Lamp/Fixture type to MR16 and hit search, a list of the approved bulbs will appear at the bottom of the page.

    For MLV transformers we could only recommend the items listed on app note #559,

    If you are locked in to using a different MR16 LED, then we would suggest contacting the LED manufacturer to see if they have a recommended dimming solution they can offer.

    Challenges of dimming low voltage LED's:

    Please let me know if you have any questions.
