LutronCaseta Original Smart Dimmer Switch ELV+ (Lutron Hub Required), 250W LED, Single-Pole/3-Way, Neutral Required, PD-5NE-WH 10-PACK, White, 10 Pack

I was having issues with a circuit with 6 LED bulbs severely flickering and interacting with other dimmer circuits with the less expensive PD-6WCL dimmer. They would severely flicker when my EV charger on the other side of the house was charging the car too.I replaced that dimmer with this one and all of the flickering issues have been resolved except for some very minor flickering at low dimming settings which can probably be resolved by adjusting the low end trim. Overall this is a way better dimmer for this circuit.

Seamless Smart Lighting Integration

Given the expense, I have been replacing my standard "dumb" switches with these smart ones a few at a time, and overall I have been very happy with their operation. They perform beautifully with only an occasional hiccup due to Siri. I've never had something fail to operate using the Lutron app for iOS or Apple's Home app.Following my recent purchase of a few more PD-5NE's, however, I did run into a problem with one load. The fixture, driven by a 12V/300W magnetic low voltage (MLV) transformer, consists of three incandescent bi-pin halogens of 50W each. When I installed the PD-5NE to switch this load, the lights on the fixture oscillated off and on, and some of the LEDs on the PD-5NE flashed repeatedly. I toggled the PD-5NE's default mode from reverse phase (for ELV loads) to forward phase for MLV, but the fixture still did not behave and I felt the PD-5NE start to get hot quickly. Secondly, later the PD-5NE blew its internal fuse. I contacted Lutron's tech support and they sent me a replacement PD-5NE, thinking possibly that the original one was faulty. The new PD-5NE arrived fairly quickly and upon installing it, I did not see its LEDs flashing as I did on the previous one nor did it heat up. However, as soon as I toggled the new PD-5NE to forward phase, it immediately blew its internal fuse as well. I placed another call to Lutron and the tech support guy recommended we try a PD-10NXD PRO switch instead. Unfortunately, that switch lacks the "favorite" button that the PD-5NE has, but I was willing to give it a try. Lutron quickly got the PD-10NXD PRO to me and I reviewed some details with tech support before installing it. You see, the PD-10NXD per the specs can operate without a neutral (though I have the neutral in the switch box). However, the specs do say that neutral is required for MLV loads. Lutron tech support suggested I first just try it without the neutral, stating that the switch would flash LEDs if it absolutely required the neutral. I installed it without the neutral and the switch did not flash its LEDs; i.e. it's operating fine, controlling the MLV without neutral, and seems to have no trouble at all unlike the PD-5NE it replaced. Score! Lutron stated that the max load rating for the PD-NXD is quite higher than the PD-5NE, though my transformer should have, per its specs, still functioned properly with the lower rated PD-5NE. I'm just happy that ultimately I got a workable solution.

I had a Lutron Caseta dimmer for about 10 years on my track lighting. It failed, and I replaced it with the same model, but for some reason it was totally dead. To shorten the story... I spent several days contacting Lutron tech support and finally we figured out that since I was trying to control track lights running through a transformer, that I needed this version which needs a neutral connection (I researched that this is the white wire). I hooked it up, and it works like a champ. Let me add that Lutron has GREAT customer support. They really tried to help figure out my problem, plus they're based in the US...

Unlike the non-neutral-wire products, this can shut my LED lights off completely and immediately.My only complaints about this one are [1] it doesn't go quite as dim as their non-neutral-wire switch (the PD-6WCL) and [2] it's more expensive. 250W is way more than I need for my 40W of LED bulbs.

I am trying to update some of my recessed lighting controls to add dimming from ordinary switches while also adding some ability to control it remotely. I had gone through 2 different brands of zwave dimmers and 4 different led bulbs before arriving at these. The first dimmer I tried didn't have a low end adjustment so the led bulbs would not light or turn on at the lowest dim setting. The second switch either flickered or buzzed depending on the type of LED. This dimmer worked very well with multiple brands of LED bulbs.I do not have flickering or humming with the LED bulbs I tried (Phillips, Cree). The low end is adjustable, but I did not have to since the lowest dim level was above the LED threshold. The center button is programmable to a favorite dim level. I also like the ability to always turn on to full brightness even if the dimmer was shut off at a lower dim level.This dimmer has 18 gauge wire coming off the switch which you can connect with your current wiring with a wire nut or similar. It also requires a neutral. It does not have screw terminals on the dimmer itself to connect wiring to.I also was able to easily use the Lutron app to control my lights remotely and add a programming schedule. You will need the Caseta Bridge or compatible hub to to control these through the internet/remotely. The dimmer uses Lutron's own propriety wireless protocol which I believe only a few systems support, personally I use the Bridge.Since this is technically not a fully incandescent dimmer, the wattage limit is lower for incandescent bulbs than other dimmers, but there are plenty of other options (even from Lutron) if you are using incandescent bulbs. I chose this unit specifically for LED bulb compatibility.Edit 2017/06/08: Everything is still going strong and I haven't had any issues with my previous install. Recently I installed another as a 3 way with a Pico reomte. These do not support the standard 3 way install with a traveler wire, but instead you wire it as if it is a single switch (you bypass the other switches) and you use a Pico wireless remote to control the main switch. So far it works fine. The only thing I wish the Pico remote had is an indicator like the main switch with the current dim level. I still plan on getting a few more since these work so well.
