In 2011, Philips Lighting partnered with Kolkata Municipal Corporation to test the performance of outdoor LED lighting. The results were astonishing: the system saved the city 52% in electricity costs, and effectively improved urban safety by directing light towards streets and pavements with 70% more precision.

With results like this, it is no wonder that LEDs are driving a clean lighting revolution.
And for Philips, LEDs have been a shining star of sales success. In 2013, revenues from LEDs made up 25% of Philips’ total lighting sales; a year later, they reached 34%. 
The real secret behind the success of these flexible luminaires - aside from being environmentally friendly? The ability to appeal to a wide range of consumers, from the private homeowner to the city administration looking to install new, cost-efficient lighting solutions.
By playing a leading role in the LED revolution, Philips has remained highly competitive in the market. This focus has proved such a good business proposition that in 2014 Philips invested €327 million in LEDs, around 70% of its green investment budget for that year, helping the company hit its €2 billion budget for green innovation one year early.

LED lighting is the future: it uses 50-75% less energy than traditional lighting systems, saving money and cutting carbon emissions; it reduces excessive waste because it has a longer life expectancy; it is mercury-free, and so avoids the use of hazardous substances; and it lends itself to innovative, sustainable design that simplifies disassembly and recycling.

It is estimated that if most people in the United States switched to LEDs by 2027, it could save over $30 billion in energy costs - the equivalent of electricity generated by 44 conventional power plants. 
And as the beneficial results of Philips’ contribution to the clean revolution shine across the smartly lit streets of Kolkata and into other cities across the state, a policy push towards LED market acceleration seems to be just round the corner . A promising step that demonstrates bold climate action can deliver increased financial value, and the first step in a brighter future for cities across the world.
