Why choose LED corn cob bulbs?

These bulbs have an efficiency of lasting 6000 Hours. Comparatively, any ordinary bulb will last only 1500 Hours. It is a big deal. A good LED bulb will not lose a single percentage of light before it reaches 6000 Hours.

The amount of Light a bulb can output depends upon Lumens. Lumens are the measurement of Brightness of a Light bulb. There is a minor difference between Lumens and Watt. Watt denotes the Power a bulb consumes to give brightness while Lumens is the brightness of a bulb. Lumens are usually mentioned for the LED light bulbs and not WATT. There is always confusion; watts are considered as the brightness of a bulb. Everyone considered a 100 watt bulb brighter than a 40 watt bulb. It is so, but today a 22 watt LED is more considerable than a 200 watt incandescent bulb because it produces only 800 lumens whereas 22 watts LED bulbs produce 1600 lumens. Hence, it is brighter.

For example, a bulb with 40 watt energy can give the same amount of light as a 5 Lumens LED bulb. Therefore, always look for the amount of lumens instead of Watts.
