Lutron Maestro PRO LED+ Tap Dimmer Switch for 250W LED, 500W ELV, 400W MLV, Single Pole/Multi-Location, Neutral Wire Optional, MA-PRO-WH, White

These dimmers are well thought-out and work extremely well. We already had several older, non-"PRO" Maestro dimmers in our house, which have not had a single problem over the last 15-20 years. Recently, we needed a more advanced version that could control low-voltage lights driven by an electronic transformer (ELV), which this model can. And it does. It works like a charm right out of the box, no extra programming required, no flickering, no humming, no other oddness, it just works perfectly. There's also a standard incandescent bulb on the same circuit, which dims without problem alongside the string of low-voltage lights. Perhaps the only downside is the price, which has gotten rather steep compared to our older dimmers, but this is clearly a case of "you get what you pay for," i.e. excellent value.

I love the Lutron Maestro switches. So elegant. I originally installed a Lutron Maestro LED+ dimmer switch (Model # MACL-153M-WH) as a single pole for my 8 LED kitchen can lights replacing an older Lutron Maestro switch. The lights came on but they kept flickering regardless of the adjustments I made to the switch controls. After some research, I determined that my LED can lights needed an ELV switch so I installed the Lutron Maestro PRO LED+. Worked great and fixed the flickering problem. Installed in about 20 minutes. Very easy. In fact, I was able to minimize some of the wiring created by the older switch which required wire connectors. With the Lutron Maestro PRO LED+, I inserted the wires into the connection holes in the back (no screws) and eliminated the wire connectors. The dimming features are adjustable and the fade-to-off feature is very nice.

Finally! I installed a brand new fixture over our dining room table. All brand new wiring. Brand new LED dimmer. On a 15A lighting-only circuit. No other dimmers or interference, yet it flickered wildly when dimmed. Upgraded bulbs. Flickered. Took each connection apart and tightened connections. Flickered. Upgraded to this LED PRO+ and connected the neutral to the switch. Fixed! Finally no more flicker.

This unit did not work with my HitLights LED light strip. I blinked off and on continuously and eventually would not turn on again, even thought the little lights along the left edge were cycling.

My fixture kept burning out bulbs with the forward-phase only Lutron dimmer from Home Depot that did NOT include a Neutral screw, which allows for reverse-phase operation that LED bulbs like. Now, no more humming when dimmed, short bulb lifespan or flickering. Voltage still reads about 114vac or about 8volts low with a multimeter on these dimmers even when using the neutral; this is normal and a function of the way the multimeter reads. Forward phase can still be manually programmed when using LED drivers or traditional bulbs. Setting lower limit ensures the bulbs pass the threshold to produce light when clicked on at the low end.

The best part about this dimmer is that it can switch between leading edge (traditional style dimmers) and trailing edge/reverse phase which is great for dimmable LED and CFL bulbs. Essentially the trailing edge dimmer helps lower-quality or finicky dimmable LED bulbs work more smoothly and with no or reduced buzz. In my testing, a more expensive dimmer paired with cheap dimmable bulbs makes them work better. A high quality dimmable bulb might work fine on a cheap dimmer, but pair this dimmer with high quality bulbs and it's a winning combination for smooth, flicker-free dimming over a wide range of light output. This dimmer works with or without a neutral and defaults to trailing edge when a neutral is connected automatically. It's great this can also work as a more basic leading edge dimmer when a neutral is not available at the switch box. The small dimming up and down buttons on the side allow you to use a single press for one small dimming "step" or a long press to quickly increase or reduce the light level. There are also shortcuts to jump to the lowest and highest settings. Finally it allows you to customize the low-end dimming range if your bulbs go out before the dimmer has reached it's lowest setting but I haven't need to use it with any of my bulbs.

very quick response but must be programmed for specific systems

These are able to handle many 4 inch ceiling lights and not buzz. 18 in total. I went through several trials with other dimmers but they all buzzed. Save yourself the irritation and just get this one otherwise you will do what I had to do.

Après en avoir essayé plusieurs c’est le seul qui permet vraiment de varier l’intensité lumineuse au seuil minimum d’intensité! Très pratique en soirée.

Le meilleur gradateur. J'avais 170w sur 20 led, trop paresseux pour split en deux. Ceci ma été recommandé par un électricien après avoir mesuré mon load. Vraiment très bon produit. Je vais l'installer partout dans la maison maintenant!
