Lumanor LED Lighting
What is LED Lighting?
Widely regarded as the future of lighting, Light Emitting Diode lamps deliver big energy savings, good colour rendering, dimmability and a long life, with high quality LED lamps being difficult to distinguish from incandescent lamps.
What are Lumens?
The technical definition of a lumen is given as:
"The SI unit of luminous flux, equal to the amount of light emitted per second in a unit solid angle of one steradian from a uniform source of one candela"
but for all practical puroposes it can be considered as the a measure of the luminous flux or quantity of light emitted by a source. For example, a dinner candle provides about 12 lumens while a Lumanor COB GU10 6W Warm White spotlight will provide 540-550 lumens of light.
What is CCT?
One aspect of lamp colour is its colour appearance; whether the light from the lamps looks ‘warm’ or ‘cool’, measured by the correlated colour temperature (CCT). Lamps with a warm appearance having a CCT of 2700 – 3000K are generally considered appropriate in a domestic setting. Lamps of 4000K - 6500K and above are considered ‘cool’ and are more appropriate for office and some retail applications.
What is CRI?
Colour rendering is also important. This is the ability of a light source to show surface colours as they should be, usually in comparison to a tungsten or daylight source. Lamps with poor colour rendering will distort some colours.
Colour rendering is usually assessed by the CIE colour rendering index (CRI or Ra); a number between 0 and 100, where lower values indicate poor colour rendering and higher ones good colour rendering. CRI only works for approximately white sources.
Do I need an LED driver for my lamps?
Some LED lamps, like their traditional counter-parts, require a control gear such as a driver or a transformer to work. These type of lamps include MR16 and AR111 lamps.
In order to determine whether your Lumanor LED lamp requires a driver, please visit the product page on our website to check the operating voltage (lamps with operating voltages of 220V - 240V AC run on mains supply and do not require any control gear).
This information can also be found at the base of the lamp beneath the product code.
