How to buy LED lighting: Common specs explained

How to buy LED lighting: Common specs explained

It can be a little frightening to switch to LED illumination when you're ready. A basic task may seem difficult due to the variety of words and performance indicators used.

Allow me to guide you through a few of the most typical specifications and provide you with a simple solution.

Terms for efficiency and dependability in LED lighting

Wattage 1.

Why does that matter?

Wattage is only a measurement of the amount of energy required for a lamp to illuminate.

Why is it crucial?

An LED lamp's wattage is typically going to be its most prominent selling point. While LED lighting has several advantages over conventional lights, their lower wattage usage is still their largest value.

2. substitute wattage

Why does that matter?

The wattage of the conventional light that the LED bulb or fixture is replacing is indicated by the term "replacement wattage."

Why is this crucial?

Finding an LED bulb that is bright enough to replace the one you are currently using will be made easier by considering replacement wattage. For instance, a 40W incandescent bulb would be needed to replace an LED A-Lamp, which requires only 8 watts.

Rated life 3.

Why does that matter?

An LED's rated life is the period of time during which it is supposed to function before dimming to 70% of its initial brightness.

Why is this crucial?

The rated life of a traditional light source refers to how long the product is anticipated to last before burning out. The number of hours it takes for 50% of a sample of identical products to burn out is used to determine this.

However, LEDs don't usually burn out. They gradually fade with time. Therefore, the rated life of an LED begins when the bulb is anticipated to be 30% dimmer than it was at first.

The longevity of LEDs over conventional lights is another important benefit. There are LED bulbs available that can last up to 50,000 hours instead of the halogen lamp's 4,000 hours. Remember that this indicates that after 50,000 hours, it should be at 70% brightness.

Commonly used words for light output or brightness in LED lighting

Four Lumens

Why does that matter?

Lumens are used to gauge how much light a bulb emits.

Why is it crucial?

When comparing an LED bulb to a conventional source, lumens are crucial. If an LED bulb is bright enough to completely replace your existing lamp, you can tell by comparing its lumens to those of a conventional one.

Center Beam Candle Power 5. (CBCP)

Why does that matter?

The amount of light in a beam's centre is measured by its centre beam candle power. (I know, clever.)

Why is this crucial?

This dimension is crucial for spot and accent lighting. When deciding if a light will be bright enough, it is frequently insufficient to simply utilise the lumen output.

A low CBCP may coexist with a high LUMEN output. In order to bring attention to a painting on the wall or a mannequin dressed in a sequin jumpsuit, this would imply that the light is dispersed over a big space.

If the maker has done an excellent job of concentrating the light to the centre of the beam, your sequin jumpsuit will dazzle and shimmer unlike anything other, even though the correct light source may actually have fewer lumens than comparable products.

6. Performance (lumens per watt)

Why does that matter?

A measure of efficiency is the amount of light produced per watt of energy used.

Why is this crucial?

Efficiency! Your product is operating more effectively the greater the efficacy ratio. Engineering and production procedures are being greatly improved by manufacturers, and efficacy ratings are always rising.

The majority of LEDs were around 30–50 lu/watt just a few years ago. At this time, some LEDs are over 100lu/watt, and you shouldn't accept anything less than 70lu/watt. It won't be long before the next wave of LED efficiency arrives, as labs are already reporting figures like 300lu/watt! Who wouldn't want more for a lower price?

In our article titled "MIT's "recycling light" innovation may save the incandescent light bulb," we discussed the effectiveness of LEDs and a recently developed incandescent light bulb.

Terms used frequently in LED lighting for aesthetics and colour

Intensity of colour (CCT)

Why does that matter?

Officially known as Correlated Color Temperature, colour temperature is a numerical measurement that describes the colour of light that a specific fixture or bulb will emit.

Warm light is indicated by a low number. Consider candlelight or a fireplace. (red and orange hues). An increased value denotes a cooler light, such as daylight or hospital lighting. (whites and blues). The typical ranges are from over 5000k on the cool side to about 2700k on the warm side.

Why is this crucial?

The colder temperatures (higher numbers) frequently give the impression of being "brighter," and LED makers frequently utilise lower wattages at greater colour temperatures to achieve this effect.

Now that you understand the fundamentals, let's go over a "real life" scenario.

You are relaxing in your workplace as the day is peaceful. Nothing but a table lamp with a soft, comfortable glow, your ink blotter, and a tumbler of scotch. The lamp begins to flicker as you reflect on life, have a scotch, and begin to plan your next major business move. The flicker continues. Die.

You descend three flights of stairs, through the servants' quarters, enter your storage closets after passing through your wine cellar. Drats. There are no more bulbs. You remove the dead bulb's screw and take it to your go-to retailer for lights.

You finally reach the bulbs after moving through the aisles while lamenting how your scotch at home is being diluted by the ice. Look downward. You hold a regular light bulb in your hand. It reads, "A-lamp." 540 lumens at 60w.

"Excuse me, where are your 60W A-lamps?" you ask a store employee. He laughs as he runs by you. "60 watts? Old dude, hurry up! LEDs are the technology of the future. You've never been fond of that clerk.

The rack containing the LED A-lamps is located. There are so many options and specs. Loss sets in. Overwhelming. Then you recall reading a really interesting and beneficial essay on understanding LED specifications. Something makes mental sense. somewhat like the turning on of a light.

Wattage. begin there. You see alternatives 7, 8, 10, and 13W. Which choice, though, is sensible enough?

Lumens, correct. begin with lumens. A few alternatives come in the 550–600 lumen range. enough to take the place of your 540-lumen A-lamp. Check.

wattage next. You're not a moron. You desire some energy savings. You disregard option 13W and concentrate on 7, 8, and 10W alternatives.

How is life supposed to be rated? Do we all have a scorecard? Sorry. back on course. Lighting. The 8W's rated life is 30,000 hours, although the 7 and 10W options are both rated at 50,000 hours. with the eight out.

You found a fantastic deal on a product that is rated to last the longest, has the proper size, is bright enough, and is a wonderful value. You've finished.

And you, too?

Correct colour temperature. While the 10W is "warm white 2700k," the 7W is "cool white, 5000k." Quite tricky. What a pity they only have 7 watts to get along with. I nearly fell for it.

You seize the

10W 600 lumen, 2700K warm white, 50,000 hour LED bulb

You then cash out and go home.

You chuckle to yourself after screwing it into your desk lamp and enjoying some warm, cosy light once more. It wasn't all that horrible. In my scotch, the ice didn't even melt. and resume your comfy scheming pattern to rule the world.

You see what I mean!

Bright illumination!
