A great way to have a San Mateo Electrician save energy and $ is by incorporating some simple green technologies into your living space. 

Energy efficient lights use up to 75% less energy than incandescent lighting, so not only will you be saving some money but you will also be saving the environment as well.

Energy Star-certified LED bulbs have come down in price making them affordable. Today’s models provide similar light quality to your old bulbs and can save $40 to $135 over their lifetime.   A San Mateo Electrician can help answer any questions you have about these bulbs.

How Do CFLs Work?

CFLs produce light differently than incandescent bulbs. In an incandescent, electric current runs through a wire filament and heats the filament until it starts to glow. If you need CFL’s installed, we can send a local electrical to your home for a free estimate. In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible UV light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.

CFLs need a little more energy when they are first turned on, but once the electricity starts moving, CFLs use about 70% less energy than incandescent bulbs. A CFL’s ballast helps “kick start” the CFL and then regulates the current once the electricity starts flowing.

This entire process typically takes 30 seconds to 3 minutes to complete, which is why CFLs take longer than other lights to become fully lit. Sometimes you can do it yourself. If you can’t contact instaBELL for a San Mateo electrician. CFLs with decorative covers like globe or reflector shapes have a unique design challenge that results in the tradeoff of a slower warm up time, which is why these CFLs take longer than bare spirals to reach full brightness.

Older CFLs used large and heavy magnetic ballasts that caused a buzzing noise in some bulbs. Most CFLs today — and all ENERGY STAR certified CFLs — use electronic ballasts, which do not buzz or hum.

Purchasing Tips

  1. Look for the ENERGY STAR label 
  2. Decide how much light you need
    • Remember that Lumens measure brightness, not Watts 
  3. Check the package for the bulb’s recommended use
    • New bulbs are specially designed for certain applications, let the package be your guide! 
  4. Think about the mood you want from your light
    • Choose a light color from warm to cool
