<p>[QUOTE=&quot;NeonBlurb, post: 2300937, member: 74855&quot;]Regarding dimmers:</p><p><br /></p><p>Well, it&#039;s complicated.&nbsp; (Here&#039;s the very abridged Cliff&#039;s Notes version that skips over LEDs being current devices)</p><p><br /></p><p>Often dimmers in general, and specifically LED dimmers are not just voltage regulators.&nbsp; They use PWM (pulse width modulation) to switch on and off LEDs several thousand times per second.&nbsp; When the LEDs are switched on, they are on fully, and when they are switched off they are off fully.&nbsp; Since your eyes can&#039;t perceive any switching taking place at 1000 times per second, the LEDs just appear to be on but dim.&nbsp; How dim they appear is related to how much of the time the LEDs are on and how much of the the time they are off.</p><p><br /></p><p>Even when the dimmer is just a voltage regulator it can&#039;t be used with just any LED light.&nbsp; This is because LEDs need some form of power conditioning between the 110 volts, 60 hertz AC coming from your wall and the 3-4 volts DC that an actual light emitting diode-junction needs to produce light.&nbsp; If that power conditioning circuit isn&#039;t designed to work with a dimmer then it may very well output full brightness down to some minimum and then cut out completely.[/QUOTE]</p><p><br /></p>
