Choose Shape

ENERGY STAR certified CFL and LED bulbs are available in a variety of shapes and  sizes for any application—including recessed cans, track lighting, table lamps, and more. You can even find certified bulbs that are dimmable.

Choose Brightness

For brightness, look for lumens, not watts. Lumens indicate light output. Watts indicate energy consumed. ENERGY STAR certified bulbs provide the same brightness (lumens) with less energy (watts). Use this chart to determine how many lumens you need to match the brightness of your old incandescent bulbs.

Watt Comparison Chart

Choose Colour

  • Light colour is measured on a temperature scale referred to as Kelvin (K).
  • Lower Kelvin numbers mean the light appears more yellow; higher Kelvin numbers mean the light is whiter or bluer.
  • Most ENERGY STAR certified bulbs are made to match the colour of incandescent bulbs at 2700-3000K.
  • For a whiter light, look for bulbs marked 3500-4100K.
  • For bluer white light, look for bulbs marked 5000-6500K.

Look for the Energy Star

Only bulbs that have earned the ENERGY STAR label have been independently certified and undergone extensive testing to assure that they will save energy and perform as promised. Source: http://www.energystar.gov/

Making the switch from traditional lighting to energy-efficient lighting is a smart move. Energy-efficient light bulbs are 75-90% more efficient than regular light bulbs. Plus, they last much longer.

Dimmer switches

  • Turning down the light level can save electricity and extend the life of light bulbs.
  • Before installing the dimmer switch, check to see if the bulbs you’re using are compatible with that dimmer.
  • Dimmer switches replace your standard light switch. Dimmers come in rotary, slide or switch styles to match a your needs and décor.
  • Dimmers allow you to control the intensity and amount of light needed.
  • Dimmers work with all incandescent light bulbs, most LEDs, and some CFL light bulbs. Look for specially marked CFLs and LEDs that are designed for use with a dimmer switch.

Motion Sensors

  • Ideal for rooms where you may forget to turn off the lights and for kids’ play rooms or any location where the lights do not have to be on all the time.
  • Many motion sensors can be programmed to determine the amount of time without motion before shutting off.
  • Can provide security by lighting up hallways and garages automatically.
  • Although indoor motion sensors have a greater upfront cost than a traditional single-pole light switch, the savings can be immediate and long term.
  • These devices replace your standard light switch and are directly wired to your light(s).

Indoor Timers

  • An indoor light switch timer allows you to choose the amount of time to leave lights or fans on in a specific room. Some timers have the ability to be programmed to turn on and off intermittently; important when arriving home after dark or when away for a period of time.
  • These devices allow you to set appliances or lights to turn-on or shut-off at designated times, just when they are required.
