I have been using the Philips LED tubelights from quite a long time.I have installed them in my house and office.The lights consume only 20 Watts of electricity . It has a light intensity of 2000 lumens. The tubelights are built pretty strongly and they last for a long time.They appear to be of premium quality.The battens are sleek and very narrow.Installation is very easy .The installation brackets and screws are included in the box .It is much energy efficient compared to conventional CFL tubelights . More over the light is cooler and soothing. Each tubelight sells for about Rs.350.I love its quality and I highly recommend it.
