Are LED light bulbs worth what they cost?

Absolutely! Why? Because they have qualities that set them apart from all other light sources and standard wattages you’ve grown accustomed to in your daily life like 100W, 60W, 100 Watt, 60 Watt or whichever way you want to read the numbers. That’s where the similarity ends. You can get the same light for less energy and in this article we will highlight other of the LED Light Bulb’s advantages over other kinds and show why they are not only worth the cost but also with the savings they will reap for you, makes them far cheaper than the bulbs you are using today.

Superior Characteristics

600W Industrial LED Grow PanelSounds a little trite but it is no idle boast, LED light bulbs are vastly superior to other kinds of light bulbs. They out-perform incandescent and CFL bulbs in several different areas such as lifetime, efficiency, and energy savings. As mentioned above LED bulbs don’t immediately burn out, instead they dim slowly over time which enables them to be usable for a longer period of time. The average lifespan of a LED bulb can last up 50 times longer than a comparable incandescent bulb, which only lasts for around a thousand hours. Even the new CFL bulbs only last 10,000 hours, far short of the over 5 years you get from a LED. It takes a LED bulb 5 years to drop to 70% brightness.

Long lifetime

LED’s light bulbs are able to last much longer than other types of bulbs thanks to the way they are built. Incandescent bulbs have fragile filaments that burn out and can cause the bulb to fail. CFL bulbs contain starters that if broken, causes the bulb to fail (not to mention the harmful toxins used to create the light). LED’s do not contain fragile parts and are instead very durable (which will be further discussed later). They also don’t immediately burn out, instead they dim slowly over time which enables them to be usable for a longer period of time.

45W LED Grow PanelLED’s have an extremely long lifespan, between 35,000-50,000 hours. They can last 35-50x as long as incandescent bulbs (up to 1000 hours) and 3-5x as long as CFL bulbs (8,000-10,000 hours). 50,000 hours is a little over 5.5 years, but also keep in mind that you don’t leave your lights on 24/7 all year. The average amount of time a single light is on in a home is only between 3-5 hours a day. Furthermore, the 35,000-50,000 hours is how long it takes for an LED’s light output to diminish to 70% output. The bulbs can continue working past that.

As far as energy efficiency goes, LED’s are very hard to overperform. As you can see from graphs, LED Bulbs are over 8 times more efficient than incandescent bulbs and twice as efficient as CFL’s. The reason the other bulbs are so inefficient is because of their processes of converting energy to light.
Incandescent bulbs operate on the same principle as a candle and like a candle after awhile the incandescent bulb will burn out and fail. The main problem is that over 80% of the energy used to make light is wasted as heat. This means you are paying not only to light a room, you are wasting hundreds if not thousands of dollars each year.

CFL bulbs are a little better. They go through a 2-step process, electricity is converted into ultra-violet light and absorbed by a phosphor coating. The absorption is what creates the light. Energy is wasted in converting the electricity to ultra-violet light first.

LED bulbs produce light through a solid semi-conductor action. When electricity hits the semi-conductor, free-floating electrons move from one side to the other. This electron movement is what creates the light. This method is the most efficient method nowadays.

Great durability

LED light bulbs are mostly made up of plastic and aluminum, not glass. This means they can take a fall without breaking. Broken incandescent bulbs are dangerous due to glass shards, and CFL’s have an added danger: mercury. The only thing that could really damage an LED is exposure to high temperatures (over 100 degrees C). Some lights can also be damaged by water, so be careful with that too.

Quality

Solid-state electronics are manufactured under clean room conditions and the manufacturing process itself insures that each LED light passes strict QA standards before being allowed off the assembly floor. The price may be higher than for incandescent lights but it is well worth the price in terms of longevity and ruggedness.

You can now see why LED Bulbs are worth the price. Next time you need a light bulb replacement, get an LED Bulb and watch the savings overtime. Longevity, Dependability and Energy savings are what make LED bulbs worth the price.
