I can't locate the Lutron D1500 dimmer switch on Lutron web site. Perhaps there is a different number for it.

Anyway, you are attempting to dim a total of 800 watts of light. A standard dimmer switch will not handle this much of a load as they are rated for 600 watts. A 1000 dimmer is the next size up and would be the minimum rating to be used. This means the dimmer would be operating at 80% of capacity and the switch may become warm - but all within acceptable limits.

A dimmer switch rated at 1200 watts or even 1500 watts may be a better choice, as the 800 watt load would present a load that would only be 66% and 53% (respectively) of rated capacity, and would likely run cooler and last a lot longer.

The down side to these higher wattage rated switches is their cost. It is not unusual for the price to double for a 600w vs a 1000w dimmer.

Sometimes, a 1000w dimmer is not sufficient to control a 600w load. This happens when 2 or more dimmer switches are installed in a single location under one wall plate. It is a fairly common arrangement for electricians to install 2, 3 or more "ganged boxes" so that there aren't 2, 3 or more individual switches clustered around a doorway. Even though a two ganged box has twice the area of a one gang box, the issue is about heat dissipation. A box will contain the heat. So the heat is given up from the front of the switch. The metal fins provide more area for cooling. When two or more dimmers are located in a multiple-ganged box, there is too much heat for the space. Two 600 watt dimmers would need to be derated to about 450 watts each (instructions for derating are included with the switch - each manufacturer has their own formulas), and if three 600 watt dimmers were in a single location, they might need to be derated to 300 watts each. So, simply moving to a 1000 watt or 1200 watt dimmer may not get you to the 600 watt level if there are several dimmers that require derating to 50%. Installing dimmers in boxes with standard "toggle" type (non-dimming) switches require no derating as toggle switches do not produce appreciable heat.

Make sure that the lighting load is a type designed for dimming. The popular CFL (compact fluorescent lamps) are not designed for dimming, unless the package specifically states otherwise. Lights that have a filiment but no transformer, ballast, starter, etc. are the only ones suitable for use with a dimmer (again - unless the package / fixture states otherwise). The dimmable types are typically "standard" incandescent, quartz, halogen and tungsten types.

Furthermore, a dimmer switch is not suitable for use as a fan speed control either. There are special switches to provide speed control of fan motors. Use of a dimmer on a motor load is a fire hazard.

I hope this helps & good luck!

SOURCE: A fixture on a Lutron Maestro dimmer switch stopped working.

This dimmer was not made to dim a load smaller than 40VA. That halogen bulb would only have been 20VA or so.

http://www.lutron.com/cms400/PageBuyNow.aspx?id=16977&mn=1815

I think that when your bulb burnt out, the dimmer over-volted the transformer and smoked it. That said, I think you have a fixture problem and, possibly, a switch problem, too.

SOURCE: replaced existing Lutron skylark low voltage dimmer

You will need to return the 3-way dimmer and get a single pole dimmer, as the Lutron Skylark series is suspectible to failure if connected to a live circuit first, or misconnected at intial installation. As an electrician, I ceased using these dimmers years ago, due to the rash of call-backs by customers and went with Leviton togglers and have had excellent results.

If you purchased it at a 'big box' store, they will accept the return as a defective item, as they have national agreements with their suppliers to accept customer returns. Just tell them it didn't work and you want a store credit, you can then purchase the lower priced single pole dimmer you need and save some money in the process too.

Hope you find this Very Helpful - best regards!

The Lutron Maestro dimmer isn't rated or designed to operate low voltage lighting as it is a 120 V-AC rated electronic dimmer. You should either install a standard low voltage ON/OFF switch on this installation or obtain a dimmer rated for use on low voltage lights.

You need special low voltage dimmer designed for use on the low voltage pucks lights you have installed. Usually the low voltage is either 12, 24, or 36 volts, depending on the manufacturer of your particular light set. Once the correct dimmer is in place, the problem with the flickering and pulsing of the lights, should cease.

If you still are having this problem and you can't find a low voltage dimmer, you can contact the maker of your low voltage light kit and they can provide you with an acceptable dimmer option for your lights.

Most Home Depot and Lowe's carry the low voltage puck light kits, and usually have accessories for these lights, including dimmer switches that will work with them.

Hope you find this Very Helpful and best regards!

The best thing you can do is call Lutron's tech support. It is a 24-hour, 7-day/week service and its free.

Having said that,

If the lights dim every 12-to-25 seconds, it tells me that something's effecting the line-voltage of the circuit. Sharing neutrals between two-lighting circuits is a common culprit, but I'm also wondering if there are other devices running off of those circuits besides the lighting. So what I'd recommend:

1) Try running both circuits off of the same phase in the breaker panel. Actually, at 7.9-Amps & 4.5-Amps (I'm assuming that's what you meant), you should be able to run them off of the same breaker. If that fixes the problem, your issue was most likely common neutral interaction. Solve by running a separate neutral... or... if you can swing it (assuming there are no other loads) leave it on that breaker.
2) Upgrade to a spec-grade dimmer like the NT-600-WH. The spec-grade products will compensate for line-voltage fluctuations that may occur from other devices that cause the line sag or un-sag.

Again, those are two base-level suggestions, but use tech support to take it a step further.

Hello. There could be a couple of possibilities. First is the simplest to verify, is it a Companion Dimmer, Standard Dimmer switches or a 600W or 1000W Maestro Wireless Multi-location Dimmer. The Maestro Companion Dimmers can not be used individually, as they do not control a load, and must be used along with a Maestro or Maestro Wireless Multi-location Dimmer. The Campanion Dimmers are also a line/low voltage rating, and rated for incandescent and halogen but may not handle some flourescent fixtures. The other thing I can think of is that you may have interfearence from another item. They are radio frequency (RF) devices that communicate together for wireless control of lights. Here's two links that may be of some help, the second has downloadable install instructions.

The LED indicators on my Lutron Maestro continuously run up and down without stopping and the lights (or fan) will not work? It seems as if the entire switch is frozen... Whats the problem?


1) If this installation was working before, the Maestro has a small pull-out circuit breaker that lets you reset the device. This is called the FASS Front Accessible Service Switch, located at bottom of dimmer where it meets cover plate.
Open sample Lutron Maestro dimmer manual to see FASS illustration
http://www.lutron.com/TechnicalDocumentLibrary/0301106A.pdf

2) If this is new installation, then double-check your wiring and check that load matches dimmer capacity: 600 watt incandescent or halogen, which apparently excludes CFLs.
Some electronic devices have shortened lifespan on circuits that are not clean. Use circuit analyzer on nearby outlet that is on same breaker to see if line has interference.


3) Lutron has customer service numbers:

Lutron dimmers throught the house, lights go high brightness to low all by themselves, is this just a bad dimmer?


I have spent considerable time on the Lutron site past couple days looking at their dimmers.

Lutron has a lot of dimmer varieties. The basic breakdown is 600Watt and 1000Watt. But different dimmers control different types of lighting.
Here is the long list of Lutron dimmer manuals:

I cannot find a specific troubleshoot manual for Lutron dimmers
So I suggest 4 things:
1) Feel the dimmer switch for heat >>> if it is getting hot (not warm), then that dimmer is dangerous, so remove dimmer immediately, add up your total bulb wattage to make sure you're below the 600 or 1000 watt capacity of you model dimmer
2) Look at the list of manuals shown at link, and make sure your dimmer matches the type of bulb you are using. Your dimmer model number and wattage should be printed on side or back of dimmer.
3) These dimmers use electronics to control the lights. Electronics go bad. The higher the wattage controlled by your dimmer, the more heat, and the shorter the dimmer life.
4) Short in the wires. Replace your dimmer with one from Home Depot and see if the condition persists. If it does, then a short is probably somewhere in that circuit. Troubleshooting a short is another long answer that needs more wiring detail ... please repost if you have a short.

First off, if your dimmer is getting hot, then there is something wrong. This is dangerous. Do not leave that dimmer in the wall. Remove it.

1) A typical wall switch controls up to 1400 Watts. Look at the watt rating of your dimmer. A 600 watt dimmer will control up to 600 watts. If you have 600 watts on your dimmer, expect a shortened lifespan for that device. If you have more than 600 Watts, expect overheating and possible fire.

2) Lutron makes 1000 Watt dimmers
http://www.lutron.com/Service-Support/Technical/InstallationInstructions/Pages/InstallationInstructions.aspx?syst=Dimmers+%26+Switches&prodn=Maestro%C2%AE+dimmer+%26+switch

3) Type of bulb: Review the specs shown on link above because they show wattage, and they also show which light the dimmer is made to control

4) If your lights are on a 3-way switch, then dimmer has 3 screws and connects to 3 wires. If your wiring is incorrect, it might give symptoms shown above.
If your switch had 2 wires and you put those wires on a dimmer with 3 screws, it might be wired incorrectly.
Check wiring. Re-post a question if your are confused about details.

5) There might be a short in the circuit ... or in the dimmer ... replace dimmer with another one from Home Depot and see if symptoms persist. Disconnect ground wire as a test only and see if symptoms disappear ... if so then there is a short somewhere in the circuit
Don't burn the house down.
