“Turn off the lights when you leave the room!” probably one of my mom’s favorite admonitions since I was a kid. Although I wonder if it’s true, do we save money and energy when we switch off the lights?
And saving money is not as simple as turning the light switch off. What else can we do?
Let’s shine a little light on the details, shall we?
It depends on the type and quality of the bulb that you use at home and the cost of electricity per kWh. Some light bulbs wear out faster than others, reducing their light-giving life more often than they are switched on and off.
Type of Lighting:
- Incandescent Lights
The least efficient light and 90% of the energy it uses is heat.
TIP: Turn Off if not in use. This will help keep a cool room in summer.
- Halogen Lights
They use the same technology as incandescent lights but more efficient than traditional incandescent lights and are less efficient than CFLs or LED bulbs.
TIP: Turn Off if not in use.
- Compact Fluorescent Lights (CFLs)
Energy efficient type.
TIP: Turn On- If you will return to a room within 15 minutes
Turn Off- If you will be gone for more than 15 minutes
- Light Emitting Diode (LED )Lights
Top energy saving lighting choice. A great option for on-off sensor operation. It also turns on at full brightness almost instantly. It uses around 75% less electricity to produce the same amount of light and last significantly longer before needing to be replaced.
TIP: Turn- On and Turn-Off whenever you like.
Electricity Conservation tips:
Households devote an average of 10% energy usage to lighting.
- Use timers to turn lights off when not in use.
- Use daylight to your advantage. Decorating with lighter colors that reflect daylight can help. Keep curtains and shades open to let in the light instead of turning on
- Maximize outdoor lighting. Motion-detector floodlights can ensure lights only come on when you need them.
