With the rapid increase in the types of Light Emitting Diodes (LEDs) it only seems a matter of time until they replace incandescent bulbs and Compact Fluorescent Lamps (CFls). The bright light, long life and low electricity consumption of an LED makes it an ideal lighting solution for households and commercial premises. Increased load shedding coupled with high electricity costs warrants the use of LEDs in every household. As solar panels gain ground in Pakistan, LED solutions are going to become even more practical and popular due to their low power consumption and high output.

Different kinds of LED bulbs

LEDs reduce your electricity bill.

In the past most of the LED lights that were available in the market had a narrow beam and focus hence they were primarily used for spot lights. However newer ones that have come out are able to provide more light over a wider area and can be used in a variety of applications for example diffused bulbs, dimmable bulbs, LED tube lights etc.

Though LEDs are more expensive as compared to incandescent bulbs and CFIs; they last much longer and consume far less electricity than the other two. For example the average cost of a 5 watt LED bulb that consumes 12 watts of energy is PKR 530, while an incandescent bulb that consumes 100 watts of energy costs PKR 40.Additionally the average life span of a LED bulb is 50,000 hours as compared to 10,000 for a CFI and 1200 for an incandescent bulb. Furthermore one LED bulb uses 500 KWh of electricity over its life span as compared to 700 KWh used by a CFI and 3000 KWh used by an incandescent bulb. This can provide significant savings as fewer replacements need to be bought coupled with a reduction in electricity bills.

LEDs are also environmentally safe as they do not contain any hazardous material that could contribute to pollution.

Some other features of the three types of bulbs are outlined in the table below.

Light Emitting Diodes (LEDs) Compact Fluorescent Lamps (CFls). Incandescent Bulbs
Turns on Instantly Yes No Yes
Frequent on/off No effect Reduces lifespan Some effect
Durability Durable Fragile Fragile
Sensitivity to temperature No Yes Sensitive

LED lights last longer, save time, labor and more importantly money. With an increase in variety and popularity, LEDS seem poised to become the future of lighting.
