How To Reduce Electricity Tariff Through Efficient Lighting

I bet most of us do not have a clue that the kind of bulbs we use in our homes and offices also determines how much tariff we pay at the end of each month right? Well, here’s the catch – IT DOES!

While we like our homes looking bright and colorful with the beautiful designs of lightings and bulbs available in the market today, it is pertinent to bear in mind that lighting (bulbs) eats up as much as 20% of the annual electric bill. But using energy-efficient bulbs and making other simple changes can cut cost and reduce the tariff we pay at the end of the month dramatically – to save energy and money over time, you should consider making good lighting choices. One of the fastest ways to cut down on your energy bills is switching to energy efficient lighting.  In an average household, about 5% of energy consumption goes to lighting, replacing your regular incandescent light bulbs with compact fluorescent (CFL) or Light-emitting diode (LED) bulbs saves you so much money each year.

Now, I know you may be wondering what you stand to benefit from switching bulbs – The most obvious benefit of switching to CFL and LED light bulb is that they require significantly less energy to operate than regular incandescent bulbs. Although energy-efficient light bulbs cost more to purchase than incandescent bulbs, they offer significant savings over their lifetime since they utilize less energy and last longer. There are many choices to make in energy-efficient lightings, CFLs and LEDs are the most popular energy-efficient light bulbs.  Although energy-efficient bulbs initially cost more than traditional incandescent bulbs, they save you more money which results in significant savings on your electricity bills.

Energy saving lighting is about reducing the wattage used in a light fitting while maintaining the same light output. They generate about 25% energy as heat while incandescent bulbs give out about 90% of energy as heat.  If you have an outdoor lighting often left on for a long while, it is advisable to use CFLs or LEDs in these fixtures to save a lot of energy.

Also, CFLs and LEDs last longer from about four to thirty years, while the traditional incandescent bulbs can only last about a year. Using energy-efficient bulbs saves you the inconvenience of having to regularly purchase and replace your light bulbs.


CFLs and LEDs

Compact Fluorescent Lighting (CFLs): These are modern compact of fluorescent lighting. Compact Fluorescent is about 75% more efficient and has a lifespan of average 8,000-15,000 hours. They require a lower wattage for a similar output as compared to an incandescent bulb.

Light-Emitting Diodes (LED) LEDs are 80% more efficient and are rated to last on average around 25,000 hours. They operate at a much cooler temperature to other lighting bulbs.


Energy Saving Lighting Tips? Here are a few:

  • First and most important – do away with all incandescent bulbs, replace them with energy efficient bulbs such as LEDs and CFLs, you’d be glad you did.
  • Turn off all lights in unoccupied rooms and do same for occupied rooms when lights are not in use or really required.
  • Embrace natural light. Open curtains and blinds during daylight hours – it is not just cost-efficient but healthy as well.
  • Use the lowest wattage bulb required to meet the room’s lighting needs – do not use high wattage (big bulbs) for small spaces or rooms, it’d be a waste.
  • Turn the outdoor light out (switch off) when not in use especially during the day.
  • Consider using timers and sensors for indoor and outdoor lights – this way, the bulbs go off when they are not in use even in your absence.
  • Regularly dust your energy light bulbs and fittings – this helps the bulbs function optimally.
