Ledino lamp from Philips Lighting

If you’re thinking of switching your lights to LEDs but aren’t quite sure whether it makes fiscal sense, follow these simple steps to assess the situation.

Firstly, identify the kinds of lamps you are currently using. What is the wattage of each light in your house and how many hours of use does it get a week/month?

Next, determine which lights will give the best return on your investment. What is the reduction in wattage consumed if you were to replace each incandescent, halogen, fluorescent, and CFL light? What will replacing the light with an LED version cost? Do you need to change the whole fixture or just the bulb?

Search “LED return on investment calculator” for some useful online tools. While LEDs are lauded for being super energy-efficient, there are different degrees of energy efficiency. Look for the EU Energy Label rating found on brands such as Megaman. Its energy-efficient lamps are rated A+ or A.


+ LED lamps do not emit infrared or ultraviolet light, unlike CFL lamps which excite the mercury vapour inside the lamp, thus generating UV rays.

+ LED lamps rely on a DC electricity source, whereas traditional lamps use an AC source. Check your driver/ transformer to make sure you don’t use the wrong source for your lamp.

+ Do you use a dimmer? Check if your dimmer is compatible with the LED bulb. Otherwise, you may need to purchase a newer dimmer.
