Lighting terms Lighting technical information

AC (alternating current) An electrical current which changes direction periodically. Accent lighting Aesthetic lighting that provides emphasis, depth and decoration to draw attention to particular objects. Ambient temperature Ambient temperature relates to the average air temperature in the environment surrounding the luminaire / LED driver. Bathroom zone Suitability for a product to be installed near or in water. CCT Correlated Colour Temperature. Colour switchable Colour temperature can be switched between 3000K to 4000K or 6000K / 6500K. CRI Colour Rendering Index. DALI Digital Addressable Lighting Interface. A method of digital dimming, allowing precise control of individual light fittings by an external control system. DC (direct current) An electrical current flowing in one direction only. Dim to warm The CCT becomes warmer as the product is dimmed. Flicker A visible constant fluctuation of light output from on to off. IK rating Indicates the protection against mechanical impact. Rated from IK00 to IK10. Insulation coverable Insulation can be laid directly on top of the product this can refer to rolled or blown wool insulation. IP rating Ingress Protection Rating. Kelvin (K) Kelvin is the scientific unit for measuring CCT (Correlated Colour Temperature).

L70, B10 / L70, B50 Lifetime indication of the LEDs. L represents the percentage of lumens at the lifetime hours and B represents the failure rate to meet L. L70, B10 at 50,000 hours means that at 50,000 hours, the LED keeps 70% of it's light output and 10% have failed to do so. Leading edge dimmers The electrical current (sinusoidal signal) is turned off at the front of the AC input waveform immediately after the zero crossing. Lumens (lm) The quantity of light emitted from a light source that is visible. The higher the lumens, the brighter the light. Luminaire Is a light fitting that contains a light source, mechanical fixings and a power supply. Luminous efficacy Is a measure of energy efficiency and is calculated by dividing the lumens by the wattage (lm/W). Luminous flux Total number of ‘lumens’ emitted from a light source. Lux (lx) Quantity of light that illuminates a surface, e.g. in a corridor 100 lux are required on the floor. Maintained Maintained fittings are on all the time, like a normal luminaire. mA A milliamp is one thousandth of an amp (0.001A). Collingwood products are typically designed to take 350mA, 700mA, 900mA. Manual test The battery of tests need to be conducted by an individual, or team, on each relevant product. Microwave sensor A presence sensor to reduce the amount of time lighting is left on unnecessarily. Non maintained Non-maintained fittings only turn on in the event of a power failure. PIR Passive Infrared Device, used to activate lighting when a person enters a room or area.

REACH Registration, Evaluation, Authorisation & Restriction of Chemicals. All Collingwood products are REACH compliant. RGBW Stands for Red, Green, Blue, White. Used to describe colour changing products that can be used to dynamically add colour to any environment. Can also be run on white when natural lighting is required. RGBWW RGBWW: This is a 5-in-1 LED chip that contains a warm white, RGB and cool white element. RoHS Restriction of Hazardous Substances, an EU requirement that restricts the use of harmful materials within products. All Collingwood products are RoHS compliant. Self Test Self-test products have built in technology that facilitates an automation of testing regimes. SELV Separated Extra Low Voltage. A low voltage power supply that will not exceed 50V AC or 120V DC. Task lighting Describing the installation or retrofit of LED downlights or other lighting specifically to provide functional illumination of an environment. Thermal management LEDs are susceptible to heat. Thermal management refers to components that are designed to remove heat efficiently to ensure high light output and long lifetime from the LEDs. Trailing edge dimmers The electrical current (sinusoidal signal) is turned off at the end of the AC input waveform immediately before the zero crossing. UGR UGR stands for Unified Glare Rating. The lower the value, the more comfortable the environment. WEEE Waste Electrical and Electronic Equipment, Collingwood is part of a WEEE scheme. Our WEEE Registration: WEE/JC3973RV
