DOES THIS DIMMER WORK WITH LED LIGHT BULB

Your lamp is a three level dimmer as opposed to a 3 position switch.

The 3 level dimmer chops the voltage where as the 3 position switch powers 2 separate filaments (50, 100) inside the bulb either separately or all at once.

The 3-way bulb should not be necessary for an electronic 3 level dimmer. Any incandescent, or dimmable CFL or dimmable LED bulb should work.

Adjust the light sensor on the on the housing of the motion sensor.

I would prescribe you go for an amazing LED knob.
As LED knobs are the most inclining ones and give different focal points when contrasted with some other globules.
Driven knobs are financially savvy, give a more drawn out life, Saves vitality, less hurtful to human body and condition, and so forth.

There are two things coming into play here; the lamps and the dimmer(s).

First; LED and CFL type lamps that are to be used on a dimmer switch - must be identified for that use. Looks for the word dimmable on the packaging or bulb itself. These lamps are generally a little more expensive than their non-dimmable counterparts. If it does not indicate it is dimmable, then it isn't - and should not be installed on a circuit controlled by a dimmer switch.

Second; a dimmer switch that will be used to control LED and CFL bulbs (that are identified for use with a dimmer) must also be identified for use with dimmable LED and CFL bulbs. Again, these dimmer switches will be identified for this use and will cost more than those that work with standard filament type bulbs.

Lutron has dimmers for your circuit called a "C•L™ Dimmer" and supports Incandescent / Halogen, Dimmable Compact Fluorescent (CFL) and Dimmable Light Emitting Diodes (LED) type lamps. have a look here:

Also, be wary of the total load (wattage) of the lamps being controlled. If you have multiple dimmers in the same box, derating of the switch's wattage capacity (due to increased heat) will be required.

Most old dimmer switches do not work with energy saving/led bulbs, they will work fine with the old style filament bulbs, the newer dimmer switches will be compatible with energy saving bulbs and will indicate on the packaging!

Sorry we have no part locating services here at this website.

The dimmer switch you select will depend on the type of bulbs you will be using. The 'original type ' of dimmer works with regular incandescent bulbs and halogen bulbs only. They cost around $15.00. Then there are dimmers for compact florescent (cfl) bulbs and LED lights that are dimmable, as well for regular light bulbs. These types of dimmers are more expensive, ranging in price form around $40.00 upwards.
Light Switches Dimmers

If you are replacing a single pole switch ( just one switch that operates lights) you'll need a single pole dimmer. If you are replacing a 3-way switch ( two switches that operate the same light) you'll need a 3-way dimmer.
Installing the dimmer is pretty straight forward. All dimmers come with installation instructions. Make sure you turn off the circuit breaker for the particular switch you are replacing.

Recycle the the dimmer switch and replace it with a new one. The dimmer switch was probably rated at 600 Watts. Therefore, 600 Watts/120 Volt which you house voltage equals= 5 amperes.
5 amps is the maximum current for the dimmer switch.

That means the voltage is 120V/240V with max current 5amp/2 1/2 amp. The HAI OminPro is drawing to much current and it's exceeding the the current limits of the dimmer switch.

Get a new dimmer switch that maximum current of 15 amps with 120 volt house voltage. That will fix you problem. GB....stewbison

The answer is NO. You need a Trailing Edge dimmer to control LEDs.

The Phillips master LED spot manual says:
Lighting controls: bulbs are dimmable 20-100% with ""select"" Trailing Edge RC devices

The Legrand pro21 manual does not say anything about being a Trailing edge dimmer.
http://www.legrand.com.gr/gr/gr/liblocal/internet_greece/PDFS/NOTICES/IOBL/ROOSTATES/775637EN.pdf

Legrand diagrams show what appears to be incandescent bulbs, and say nothing about LEDs

LEDs cannot be dimmed as ordinary incandescent (tungsten) bulb.
