2. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   They enable computer control via networked switches, but do not require it. Their cost is about the same as the older "dimmability" circuitry that they replace in LED bulbs, fixtures or drivers. A residential-type dimmer switch with sliding knob to change brightness. The device is small enough to fit into a regular wall box provided for a switch.

   DIY fire pit was about $50 worth of retaining wall blocks, also completely worth it. ... Adding 4 recessed lights on a dimmer switch is under $200/room and is such a quality of life improvement ...

4. 0-10 V lighting control - Wikipedia

   en.wikipedia.org/wiki/0-10_V_lighting_control

   The switch is controlled by a PWM (Pulse Width Modulation) signal, which alternately turns the switch on and off at a rapid rate. The relative proportion of off time vs. on time determines brightness. For example, if the switch is off 10% of the time, the resulting control signal would be the equivalent of 1 V produced with a variable resistor.

5. Light switch - Wikipedia

   en.wikipedia.org/wiki/Light_switch

   Two light switches in one box. The switch on the right is a dimmer switch. The switch box is covered by a decorative plate. The first light switch employing "quick-break technology" was invented by John Henry Holmes in 1884 in the Shieldfield district of Newcastle upon Tyne. [1]

6. LED strip light - Wikipedia

   en.wikipedia.org/wiki/LED_strip_light

   An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .

7. LED lamp - Wikipedia

   en.wikipedia.org/wiki/LED_lamp

   LED emitters are inherently suitable for dimming, because they can operate over a wide range of currents without significant change of color. However, the circuits in LED lamps must be explicitly designed to be dimmable and compatible with particular types of dimmer switch. [106] Otherwise damage to the lamp and/or the dimmer may result.
