How to Understand Light Bulb Wattage

Most of us grew up when shopping for light bulbs was simple and straight forward. If we wanted a brighter bulb, we bought one with more watts. That time passed several years ago when more energy efficient ways came upon the scene and were quickly adopted as the future.

Watts = power. For example, a 40W incandescent bulb uses 40 watts of power per hour. That is 40 watts of power that will be charged on your electric bill.

Lumens = light emitted. This measures the light that is actually produced by different types of bulbs.

Consider this….

An incandescent bulb uses 40W to produce 400 lumens of light. It will last about 1000 hours.

A CFL bulb (compact fluorescent) uses 9W to produce 320 lumens of light. It will last about 6000 hours.

An LED bulb uses 6W to produce 300 lumens of light, and will last a whopping 50,000 hours.

It is easy to see why incandescent bulbs have become phased out in our homes, and why LED lights are now competing with the CFL sales.

The important thing to remember is that the more watts you use, the higher the electric bill.
