How to Avoid Overlamping

Overlamping happens when a socket for a lamp has higher power than intended. Each lamp-holder socket is not designed to accommodate the common 100-watt incandescent light bulbs. This is an offense to the code and a dangerous fire hazard.

The intense heat generated by a 100-watt bulb when it is connected to a 75-watt lamp-holder socket could cause the socket's surface to be melted or scorched. Arcing can increase, and this could lead to fire hazards. Research has shown that arcing is one of the most common causes of electrical fires.

The United States system for safety standards requires that all electrical equipment be listed. Listing is a tool to ease the acceptance of electrical devices. Most lamp holders are listed to a specified wattage depending upon the type of fixture. This rating is based on factors such as the material used in its construction and where it will go. The wattage of common lamp holder sockets is 75 watts.

It's possible that some sockets located around your home are listed as being 40 watts or 25 watts. An electrician can test your sockets to confirm the maximum wattage.

Most experts agree that a bulb rated at 75 watts should be used. But you can always check with your electrician for more information. Modern high-efficiency lamps have lower energy consumption and therefore are safer. You can use a 60-watt bulb to replace older fixtures that are not marked.

If you find a lamp holder socket in your home that is looking scorched or melting, contact a professional to have it repaired. If you are unable to get help from an electrician, you can do the work yourself. Make sure that the main is off and you have all the necessary tools.
