Philips CosmoPolis Urban Lighting - Manual (Page 4)

Even better lighting at even lower costs
CosmoPolis cuts the cost of your lighting ownership
in three ways:
Increased luminous efficacy
Improvements to burner design and vapour salts have increased luminous efficacy, meaning
that you can replace the SON/CDM 70W, 100W and 150W team by CosmoGold/CosmoWhite
60/65W, 90W or 140W lamps without loss of light levels but with useful energy savings.
CosmoPolis is not retrofit with any existing lamps, but offers you impressive benefits for new or renewed installations
Reduced gear losses
Innovative electronic gear increases overall system efficiency from 83% to 92% for
further energy savings.
Improved optical performance
The optimised design and exactly aligned positioning of the burner via the twist-and-lock
lamp cap, have allowed a substantial improvement in optical performance. This means your
luminaires can be spaced some 10% further apart: you need fewer light points to achieve
the desired lighting performance.
