CMH for outdoor lighting

GE's CMH Lamps for street lighting.

Bright, safe, white light for street lighting

It is widely recognized that white light improves road safety, making it easier for drivers to recognize shapes and colour, particularly in the peripheral vision. For pedestrians white light promotes a feeling of security and confidence, much more than under yellow or orange street lighting.

CMH lighting delivers competitive levels of light, of higher quality, with lower energy consumption. It combines the efficiency of HPS with the whiteness of metal halide, while delivering a broader spectrum than mercury.

City beautification – transforming buildings and public spaces with GE CMH

Traditional lighting can leave public spaces feeling dark and uninviting, deterring visitors at night. The use of CMH technology not transforms the atmosphere and appeal of parks and urban areas after-dark, but also reveals the true colour and detail of statues, sculptures and other works of public art. No wonder so many cities are now turning to GE's Ceramic Metal Halide technologies.
