Switching to CosmoPolis also cuts your energy bills. The system efficiency is higher, from 30% up to 70% compared to other white light source. What’s more, they retain their brightness to the end of their long, reliable lifetime, reducing maintenance costs along the way. The high optical efficiency allows you to increase spacing between luminaires, lowering you initial investment too.

Energy savings significantly reduce CO₂ emissions. CosmoPolis has been designated a Philips Green Flagship product because of the tremendous energy saving potential it offers compared with conventional light sources, saving money and reducing waste. Its long service life means less manufacturing and recycling and the reduced luminaire size also cuts packing and transport volume.

CosmoPolis is a new generation of compact ceramic metal halide lamps for outdoor public lighting. It offers high-quality, warm white light, improved service life, plus the highest lamp and system efficiency available. CosmoPolis uses 50% less energy than mercury vapour lighting (saving more than 100kg CO₂ per lamp on an annual basis). Even greater energy savings can be achieved with automatic dimming.

The municipality of Porto in Portugal wanted environmentally-friendly lighting that combined low energy costs with low maintenance and an improved ambience. MASTER CosmoWhite and MASTER CityWhite running on PrimaVision electronic ballasts provided an ideal solution. Lead-free with a low mercury content, super-efficient CosmoWhite saves energy and cuts CO₂ emissions. The PrimaVision gear also has a service life of 60,000 hours.
The new warm white has had a dramatic effect on the night-time ambience of the centre of Porto. People sitting at pavement tables now feel part of the café instead of being outside it, and the squares themselves seem larger and more welcoming.
