Terms for LEDs EXPLAINED Finally!

To be able to make a healthy start, you had better learn the terms that are used for LEDs. Switching to LED? Here are some things for you to read before doing so. Imagine this like a buyer’s story. Storytelling is something accepted. They have methods and strategies to tell stories. BUT there is nothing like “guidetelling” or “termtelling.” Or is there? My type corrector is breathlessly warning me at the moment. You know, it is never easy to invent or produce something for the first time. I’ve developed some skills to explain annoying things, but only a few thousands of viewers won’t be enough to spread the word. Then, five years later, someone will come up with an obviously similar idea with worse performance to earn millions. I’d love to (but I can’t) set background like the one in this video or this while you’re reading about these. Sorry, let’s go back to business.

There are several things relating to the performance according to the statistics and metrics. When outsider buyers view LED items, they’re left helpless! If they have much money, will they go for the biggest numbers of everything? Of course not! Efficiency is one of the main concerns. The light output, visual appeal, and product features are also essential, but how will we understand those?

Performance of LEDs

The most straightforward measurement can be a wattage measurement to understand the worth. We can simply define it as the wattage required per illumination point. That’s the main reason why people would switch into LEDs. They call it replacement wattage when they compare it to traditional bulbs, which are currently used by a serious number of people. If you want to read our topic specifically written for comparison, you can visit the inserted blue link.

Rated life of LEDs is also vital but very easy to understand. It indicates the expected operation lifespan. Keeping the bulb alive is not enough. It should remain alive without dimming or without starting to flash-flash flickers.  Imagine we had to write our lifespan to our ID. Even when we’re 110 years old, it wouldn’t be 110 years. Most of us would write 35! Many LED options available in the market are claimed to be thirty-percent dimmer before they start behaving worn out. The manufacturers mostly guarantee about around 20000 hours.

The Terms; Lumens, Center Beam Candle Power, Efficacy for LEDs

The amount of light produced is measured with Lumens. Manufacturers and sellers also might call it brightness.

terms for LEDs: Lumens/W

Center Beam Candle Power is often shortened as CBCP. As you can understand from its name, it is mostly related to the center. In other words, the intensity of the center beam of light beams measured by CBCP values. Typically, Lumens are enough to measure brightness levels for most of the purposes. However, if the concept is accent lighting or spotlighting, CBCP becomes essential. You know, the center beam is expected to highlight something in those scenarios.

The amount of light production is also called as efficacy.  A high ratio of efficacy indicates higher quality and better performance. It is from Lumens / Watts.

Visual Value Terms for LEDs

You must have seen CCT somewhere if you browsed into shops. That is simply the color temperature value in numerics. That is not related to performance. For instance, if the number is low, no one calls it underperforming. Instead, they call it warm light. It sounds quite positive, right? On the other side, a higher value number is not related to excellent performance. Instead, they call it cool light. So, if you are content with the current visual in your rooms or wherever, you should learn the CCT value of your current bulbs when you decide to replace them. 10000K is undoubtedly not for the bedroom.

terms for LEDs: Correlated Color Temperature (CCT) visualized

The LED world is full of “C.” Here is another thing: CRI. Accuracy of color reflection is called CRI, which means the Color Rendering Index. People require high values where a visual distinction is important. So, low CRI value bulbs are still useful somewhere else. Will it count as a mature content if I just say low CRI is welcome in Amsterdam? If not, I have a better option. Low CRI is welcome in the road tunnels.

We don’t forget to mention dimmable LEDs. You can see that not all the options are dimmable. It wasn’t a problem for incandescent lamps because their principle was born dimmable. To better say, it was a resistance-based invention by Edison. Buying a dimmable LED lamp won’t be enough by itself. Your fixtures and power switches should enable this feature as well.

Comparison (LEDs to LEDs)

You should never judge products solely with the values like CRI, Lumens, W, CBCP, etc. Different values could still belong to high-quality LEDs. However, your purpose defines the better choice. Once you find the correct values and decide the type of LED to buy, then the price, Lumens per Watt/Efficacy, and lifespan will be necessary.

You must find the lighting facts behind the pack. If you’re shopping online, the sellers already provide this detailed info. Here are the typical steps to take for comparison when you find two similar offers for LED lights.

  • You will check the brand experience.
  • Watts (consumption or required power to run the device)
  • Lumens per Watt. In other words, “Efficacy.”
  • Certification. For instance IESNA (Industry Standardized Testing Procedure)
  • CRI ındex (if the color distinction is vital for the place of application)
  • Price/count

LIFESPAN

LEDs are not immortal yet very reliable. The name of the brand and the reliability of the company is, therefore, vital. If a company gives a warranty of five years, it should also be able to give a warranty for their company to stay on the market for at least five years. Provided that you can rely on the claims like 25000 hours lifespan or 5 years warranty, etc.

Conclusion

Please, remind me if I forgot defining some terms for LEDs. If you still have specific questions, feel free to ask here for free. Otherwise, interior architects won’t feel free in terms of LEDs.
