2. Holiday lighting technology - Wikipedia

   en.wikipedia.org/wiki/Holiday_lighting_technology

   Holiday lights of this type do not suffer from color fading because the light is determined by the LED's chip rather than the plastic lens. White LEDs are similar in most respects such as power and durability, but utilize a two-stage process to create the white (polychromatic, or broad spectrum) light.

3. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   All NEMA 6 devices are three-wire grounding devices (hot-hot-ground) used for 208 and 240 V circuits and rated for 250 V maximum, with the 6-15, 6-20 and 6-30 being grounding versions of the 2-15, 2-20 and 2-30, respectively. The 6-15 resembles the 5-15, but with collinear horizontal pins, spaced 23 ⁄ 32 in (18.3 mm) center-to-center. The 20 ...

4. Regulated power supply - Wikipedia

   en.wikipedia.org/wiki/Regulated_power_supply

   The front panel typically has LED indicators for "C.V." ("constant voltage") and "C.C." ("constant current"). When the current demanded by the load exceeds the limit set by the user, the power supply automatically switches to the latter mode by regulating the voltage down so much as to prevent the current limit from being exceeded.

5. Electrical ballast - Wikipedia

   en.wikipedia.org/wiki/Electrical_ballast

   A typical 230V, 50hz series choke ballast (inductor) used in older lighting. This example is used for a tanning lamp. It requires a starter switch (below). A lamp starter, required with some inductor type ballasts. It connects the two ends of the lamp to preheat them for one second before lighting.

6. Transformer - Wikipedia

   en.wikipedia.org/wiki/Transformer

   In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
