How to buy an LED Bulb

Lighting | Appliance wattage advisor | LED bulb buying guide

What to consider before you buy an LED bulb


These sort of bulbs are composed of a number of Light Emitting Diodes (LEDs) all enclosed together to produce a bright white light. See our article on Energy Efficient Light Bulbs for more information on their mode of operation. They are commonly used in modern digital display technology; example, telephones, TVs, etc. In general, the higher the brightness, the higher the wattage which in turn imparts electricity use. Buyers must therefore strike balance between the cost and the convenience of use.


Power Consumption

An LED light bulb will consume only about half the power that is consumed by CFL bulbs. They could last 50,000 hours, or about 5.7 years of 24/7 lighting. While they may be pricier, the LED bulbs are a valuable investment, and will reduce your energy consumption further. In order words, while the CFL is cheaper than the traditional incandescent, the LED provides further energy saving than the CFL.

LED (Watts) Lumens (Brightness)
6 – 9 400 – 500
8 -12.5 650 – 900
13+ 1100 – 1750
16 – 20 1800+
25 – 28 2780+

Always remember to check for warranty. The duration of the warranty determines the confidence the manufacturer has in the product. Therefore the longer the warranty, the more confident the manufacturer is that the product is durable. Never buy an appliance with no warranty! Also, look out for the lifespan (total number of hours) of the bulb. Finally, you should buy from an authorized dealer to ensure that the warranty is valid.



There are many LED bulb brands in the market. Always check for the SONCAP and Energy Star certificates, as well as the warranty (as said above).
