Question about Lutron Electrical Supplies
Is there something else in the circuit besides the breaker, dimmer switch and the bulbs??
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: humming inside the switch
Is it connected to a fan motor also? - most dimmers are for lights only - if there is a ceiling fan connected you may experience a humming sound from the dimmer

there is not way to know how the wires are run by the description.
it is possible to connct true 3-way switch, it will required additonal pair of wires to all 3 switches (meaning 3-14/3 wire).
so call 3-way switches is only two way. I have not seems a real 3-way switches.
go to the following site. they a connection diag. for the switches.

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

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!

Testimonial: "I appreciate your help."
SOURCE: LUTRON DIMMER
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!
PS: I found this old, unanswered question and wanted to provide a solution to close out the problem and clear the question from the site.

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.
