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.

How to Choose the Right Outdoor Extension Cord

Extension cords … how we do love thee! But most Charlotte residents have not taken the time to truly understand our extension cords. Are they all made the same? Does the length matter, except for convenience? What makes one outdoor extension cord better then another?

Last blog we discussed “Outdoor Extension Cord Safety”. This time we’re going to explain how to choose the right extension cord for the job on hand.

IMPORTANT NOTES

UL symbol – These means that the cord has been approved by the Underwriters Laboratories.
W – Marked “For Outdoor Use” and their coatings have been designed to prevent moisture entry.
Gauge/Wires – The packaging on the extension cord should have a numerical rating. For example, 14/3 means It is 14 gauge and has 3 wires inside.

WHAT SIZE?

The smaller the gauge number, the thicker the wire is, and the more electricity it can handle. But at the same time, keep in mind that the longer distance the current will need to travel, the thicker the wire (gauge) will need to be. Which is why buying only the correct length that is needed for the job is a more safety cautious rule of thumb.

This may seem confusing, but choosing the right outdoor extension cord is important for your family’s safety. Especially if you will be using it to run an outdoor appliance that requires a lot of juice.

If you find yourself relying on multiple extension cords, that could signal that it is time to increase the number of outlets in your outdoor area.
