How are Lumens Measured?
Lumens are typically measured at the source, the bare lamp level. But this does not accurately account for a “real-life” scenario of the lumens. There could be environmental factors such as weather or heat which impact the lumens in the real world, or even the type of fixture the lamp is installed in. Diffuser or protective covers can block 20% of the light from being transmitted to the target destination.Read More

As an airplane hovers over Cochin International Airport, one is struck by the dazzling array of reflective panels near the runway.
Standing out in a field of green are more than 46,000 solar panels tapping the power of the bright sunlight and converting it into energy.
Located in the southern state of Kerala, Cochin is now the first airport in the world to run completely on solar power.
The airport started with a small pilot project by installing a solar energy plant with 400 panels on its rooftop in 2013. When that experiment succeeded, it decided to go all the way.
In August this year, the airport became totally self sufficient in meeting its energy needs after it installed a 12 megawatt solar plant close to the cargo terminal.
The airport's managing director VJ Kurian says it was the huge power bills that prompted them to look at greener solutions.
