LED Light Bulbs
April 17, 2019
Many homeowners who want to save on energy costs are upgrading to LED light bulbs. LED stands for Light Emitting Diode which is a semiconductor source that produces light when an electrical current passes through it. Back in 2014 when incandescent light bulbs were being phased out, homeowners were encouraged to switch to the more energy efficient CFL bulb. Five years later, LED light bulbs have become the more popular choice because they are even more energy efficient than the CFL light bulbs. CFL light bulbs use 35% less energy than the incandescent lights bulbs. LED light bulbs, however, use 75% less energy than the incandescent light bulbs.
Incandescent Bulbs: 90% of the energy used is to produce heat. Average Life Span is 1,200 hours.
CFL Bulbs: 30% of the energy used is to produce heat. Average Life Span is 8,000 hours.
LED Bulbs: 0% or very little of the energy used is wasted to produce heat. Average Life Span is 25,000 hours.
Below are some advantages and disadvantages of LED light bulbs compared to CFL light bulbs.
Advantages of LED Light Bulbs
LED bulbs last about 3 times longer than CFL which means they have a very long lifespan and less maintenance and replacement costs.
They turn on fully right away. CFL bulbs take a few seconds to warm up and fully turn on.
LEDs use less wattage and therefore less energy
They can be compact in size and are available for most applications
The bulbs are more durable and resistant to breakage
They are not affected by constant turning on/off like other bulbs
They are dimmable
There is no mercury or lead in LED light bulbs
They don’t produce heat so the bulb stays cool to the touch
Rapidly developing technology
Disadvantages of LED Light Bulbs
It is difficult to find many disadvantages to the LED technology other than
They can be more expensive than other bulbs, although price has continued to drop significantly
In hot environments, the life span can decrease, ie sauna, steam room or enclosed fixtures

You might feel grounded after a year of Covid-19 home isolation, but cheated out of the experience of bad behaviour to justify it. Webster’s Dictionary defines grounded as ‘mentally and emotionally stable, sensible, realistic and well-balanced. All things we... READ MORE
