Glossary of Technical LED Terms

LED (Light-emitting diode) is semiconductor diode that converts applied voltage to light and is used in lamps and digital displays. LED light bulbs are durable and offer comparable or better light quality than other types of lighting. It is a highly energy efficient lighting technology that uses at least 75% less energy than incandescent lighting.

An IP Rating measures the level of protection against the ingress of foreign objects into the enclosure for a piece of electronic equipment. The two-letter IP followed by two numerals indicates the Ingress Protection. The higher the value of each digit; the greater the protection.

A CCT (Correlated Color Temperature) is a specification of the appearance of the light relative to a blackbody at a particular temperature in Kelvin (K).

RGB (Red Green Blue) is a tri-color additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors.

A warm white Integral LED lamp will provide a traditional yellowish color light, similar to conventional bulbs. It creates a relaxing atmosphere of wellbeing. It is appreciated in homes, restaurant.

It gives a clear, white light with very little red or blue tones, but appears more “cooler” than halogen light. It gives a natural color and is appreciated in showrooms, office areas…

A cool white Integral LED lamp will provide a modern, clean, bright light that is slightly blue in color. It gives a high-tech touch and is appreciated in retail, hospital, and workspace. On down the scale, the color becomes "warmer" due to the dominance of red and yellow hues. In contrast, white will have cooler colors in which blues and green become more apparent than in warm white.

Lm/W (Lumens/Watts) is a measurement of luminous efficacy, which is the light output in lumens using one watt of electricity. Watts’s measure the amount of energy required to light products, whereas Lumens measure the amount of light produced. The more lumens in a light bulb, the brighter the light.

SMD LED (Surface Mounting Device): is a type of LED module that uses Surface-mount technology (SMT) to mount LED chips on printed circuit boards (PCB).

COB LED (Chip-On-Board) is a technology of LED packaging for LED light engine that interconnect bare chip. Multi LED chips are packaged together as one lighting module.

Wattage Equivalent is LED's comparison to incandescent light. It gives an indication of energy saving.

Risk Group 0- RG 0(exempt): LED products must meet photobiological safety standards. (No photobiological hazard)

Dimmable: Able to have illumination decreased in brightness, to adjust the light intensity.
