With all those energy saving Bulbs, Spot, Tubes m.m we dont measure Performance in Watts anymore, so what you need to look for is how much is the output of Lumen.

• Watts are simply the amount of electricity a bulb needs to operate/shine, while the light output / brightness of the bulb is actually measured in LUMENS.

Quality bulbs like Vilight offer a wide variety of shades of white light, yellowish to white to bluish white light, which allows you to place the right Bulbs in the Right Room, like in a Garage cool white would look good, but in the Bedroom maybe a warmer light is better. Many qualified bulbs come in warm colors to match the yellowish light of incandescent bulbs, but you can also pick cooler colors with whiter or bluer light.
