PHILIPS - discharge lamps and ballasts
Philips offers a wide range of discharge lamps. The aim of this article is therefore to help you navigate through this range. It should help you to select the best light source for your chosen application. It will serve as a guide to introduce you to the lighting characteristics of these lamps and the applications in which their advantages are best exploited.
Philips MASTER series power supplies
Perfect light, perfect sense. The MASTER series products, with their excellent light characteristics, not only provide perfect light quality, but are also perfect from an economic point of view. Thanks to their excellent energy-saving and lifetime reliability, PHILIPS MASTER Series products minimize the total investment cost of operating your lighting.
Philips protects the environment
Legislative requirements to limit the environmental impact of lighting are increasing and must be taken into account when choosing your lighting solution. Using Philips products will reinforce your responsible approach to this issue.Philips Green Flagship products achieve maximum lighting quality with minimum environmental impact. Our Green Flagship products exceed the requirements of the European standard limiting the impact of hazardous substances, their energy efficiency leads to reduced emissions CO2 emissions, and their longer lifetime and higher reliability over this period leads to fewer replacements and reduced waste disposal costs.
Light characteristics
All light sources, especially discharge lamps, produce light of a certain quality, which is described in technical documentation and other specialised literature. Knowledge of this information is essential for the correct selection of the right type of light source for the application.
Colour rendering index (Ra)
Unlike incandescent or daylight, the natural tone of lamp light does not contain all the colours of the visible spectrum. The ability of these light sources to render colours faithfully is measured on a colour rendering scale. The scale ranges from a value of 0, indicating very strong colour distortion, to a value of 100 indicating zero distortion.
Chromaticity temperature (K)
The temperature of light expressed in degrees Kelvin.Warm white light (up to 3,300 K) corresponds to the light at sunrise or sunset, evoking a feeling of relaxation and rest. Neutral white light has a chromaticity temperature between 3,300 K and 5,000 K. Cool daylight (above 5000 K) creates an atmosphere of liveliness and high performance.
Luminous flux
A measure of the total amount of light emitted by a light source in all directions. The unit of luminous flux is the lumen (lm).
Total investment cost
When you buy light sources, luminaires and other related equipment, you are actually buying light. The actual cost of that light is the sum of three items: investment cost, energy consumed and maintenance cost, with energy cost always being the most significant part. If you reduce maintenance costs by extending the lifetime or increasing the reliability rate, you can achievereduce the total investment cost despite a higher initial investment.
