Certifications/Compliance
Standards and certifications comprise a vast number of companies and compliances that serve specific purposes—primarily addressing safety, environmental impact, energy efficiency, and sanitation. They are divided into categories for each product type and certification type to allow for very specific qualifications related to each product. When this system is being used as intended, it gives consumers, installers, suppliers, and anyone else who may be involved confidence that the product is safe and will work well in their application. UL and ETL certifications relate to safety and installation and are the most common for power supplies. |

Dimming Control
Dimming Control
TRIAC Dimming: This is the most commonly recognized dimming type, with TRIAC Dimmers found in most Home Centers and hardware stores. TRIAC (TRIode for Alternating Current) dimmers operate by modifying the voltage waveform, reducing the amount of power input to the device being controlled. Reducing the input power will result in a corresponding reduction in a power supply's output voltage/current or a decrease in the lumen output of a light fixture. TRIAC dimmers come in two variations: Forward Phase and Reverse Phase
0-10V Dimming: This type of dimming control is most commonly found in commercial applications. It works by varying a voltage from 0 to 10 VDC on dedicated dimming wires. The output of a power supply or light fixture is proportional to the voltage applied. Pulse-Width Modulation (PWM) Dimming: This dimming control adjusts output by rapidly turning the output on and off at a fixed frequency. The proportion of on-time to total time sets the dimming percentage. Potentiometer Dimming: Potentiometer dimming varies the output using a variable resistor, or potentiometer, to set the dimming level. |

Suitable for Dry Locations This marking indicates that you can use the light or component in a location not normally subject to dampness. This may include locations exposed to temporary dampness, such as a building under construction, provided that ventilation is adequate to prevent moisture accumulation. Use these fixtures in living rooms, bedrooms, offices, hallways, and similar areas. The marking may be "SUITABLE FOR DAMP LOCATIONS" or "DRY LOCATIONS ONLY."Suitable for Damp Locations Fixtures marked “SUITABLE FOR DAMP LOCATIONS” or “SUITABLE FOR WET LOCATIONS” can be installed in damp locations. A damp location is an exterior or interior location regularly or occasionally subject to moisture condensation on or around electrical equipment. It includes partially protected places such as covered patios and porches. Damp locations include any regularly muggy or humid area, such as above a kitchen sink or stove, and appropriately vented bathrooms near the tub or shower.Suitable for Wet Locations Fixtures and components marked "SUITABLE FOR WET LOCATIONS" can be installed in wet or damp locations. A wet location is anywhere water or other liquids may drip, splash, or flow on or against electrical equipment. A light marked "SUITABLE FOR WET LOCATIONS" may have additional markings that tell where and at what height it can be safely mounted. Uncovered outdoor areas like decks, gazebos, walls, and typical landscape lighting sites all fall under the heading of wet locations. |

Output Power
Output Power
A power supply's power consumption is measured in watts and refers to the maximum amount of power it is capable of delivering. For best results, choose a power supply that offers a minimum of 20% wattage overhead for your application. Wattage overhead ensures that your project will function correctly, extends the life of the power supply, and offers greater design flexibility by allowing for project expansion. |
