LED is an acronym for light emitting diode.

LEDs are semiconductors. When current flows to an LED, electrons recombine with holes within the device. This releases energy in the form of photons, and is known as electroluminescence, producing light.

It is important to note a couple of things. The lifetime of LEDs can be very dependent on two things: color and quality. White LEDs fade over time, and low quality LEDs fade quicker. Luxul Technology only uses the highest quality components available.

LED’s are more efficient than the other types of light bulbs because very little energy is wasted while creating light. Traditional fluorescent tubes use electricity to heat the enclosed gas to produce light. The heat created is wasted energy. The process that LED tubes use to create light wastes miniscule amounts energy converting electricity or emitting heat.

Also, Luxul Technology tubes illuminate instantly and consistently throughout, eliminating flickering that is common with traditional fluorescent tubes.

How is the brightness of LED light measured?

What is the difference between wattage and lumens?

Wattage refers solely to the amount of energy required to create light from a bulb. For example, a 75-watt bulb requires less energy than a 100-watt bulb. Interestingly enough, the amount of watts used does not relate to the brightness.

Lumens are actually a more accurate way to determine the measure the total amount of light created by a source. Just fewer than 11 lumens (10.76 to be exact) is equivalent to the amount of light that a candle produces from one (1) foot away, which is also known as a foot-candle.

What is the range of brightness?

What is CCT? What is the difference between “warm white” and “cool white”?

So who and what is Kelvin?

The Kelvin scale and Kelvin temperature are named after William Thomson, 1st Baron Kelvin, who was a the British physicist and engineer of the late 19th and early 20th century. He researched the need to have an “absolute thermometric scale.”

The Kelvin (signified by the symbol: K) is a unit increment of temperature, and one of the seven SI base units. The Kelvin scale is a thermodynamic (absolute) temperature scale where absolute zero, the theoretical absence of all thermal energy, is zero (0K).

A lower Kelvin temperature produces a “warm,” softer color, such as candlelight (2500K-3000K). A warm white has a more yellowish hue to it, hence the warmer look.

A higher Kelvin temperature produces a “cooler,” more intense the color. A cool white has a bluish hint in it, creating a colder light color. A clear Northern sky at 8000K produces an intense blue color light that goes beyond the range of currently available manmade light. A Kelvin temperature in the range of 4000K-5700K produces the whitest natural light, which is what occurs when the sun is directly overhead.

Whichever Luxul Technology product you choose depends greatly on personal preference and where the bulb will be located. Luxul Technology recognizes that every lighting scenario requires different Kelvin temperatures and emphatically does not champion one color over another; however, it is worth noting as a guide that 4000K and 5000K are standard color applications for most office settings with traditional lighting needs. Cool white might be appropriate for a high-traffic space, while warm white may be preferred for creating a more intimate ambiance, such as a restaurant or a bar.

Luxul Technology products come in six (6) color temperatures:

3000K
3500K
4000K
5000K
5700K
6500K

What is CRI?

CRI is an acronym for Color Rendering Index. It is calculated by comparing the color rendering of the test source to that of a perfect source. Theoretically, the only perfect source of light in the world is the sun, which has the highest CRI achievable - 100.

Most traditional fluorescent tubes have a CRI in the range of 50-65. All Luxul Technology products have a CRI over 80, meaning that the rendering is noticeably more accurate, producing sharper, crisp colors. This makes Luxul Technology ideal for situations where the accuracy of color rendering is critical, such as department stores and clothing boutiques.

What is the formula to figure out how much I’ll save with LED lights?

You can determine how much you would save on energy using Luxul Technology products vs. traditional fluorescent tubes by using this equation:

[(A x B x C)/1000] x D = Cost per day

A = Number of estimated hours on average a fluorescent bulb is used

B= Number of fluorescent tubes replaced by Luxul Technology LED tubes

C= Wattages of the fluorescent tubes being replaced

D= How much you pay per kilowatt-hour (kWh) (look at your electric bill or contact your local power company for this information)

This equation will determine the cost per day for both current bulbs and Luxul Technology replacements. Subtract the Luxul Technology value from your current fluorescent bulb’s value. This is how much you will save each day by using LED light tubes.

If you want to determine your annual savings, multiply each cost per day by 365, and again subtract the Luxul Technology value from your current fluorescent bulb’s value.

What is LED resistance? How does it act?

There are three major concerns for this kind of product.

1) If the ballast should fail, and the internal driver is in charge, the light output of the this lamp would be different from other existing lamps. Because the specs of the internal driver must be different from the existing ballasts. Such non-uniformity lighting would be un-acceptable for most customers.

2) When old ballasts fail, customers still need to re-wire and bypass the ballasts. In that case, why not just replace the failed ballast with good ballast?

3) External ballast/driver is much more reliable than internal driver. Because the heat generated inside the tube will hurt the life span of the LEDs and the internal driver per se.

4) Due to the bulky overhead of the internal driver, the beam angle of such kind of tube would be 180 degree or less. No way to be close to Luxul’s 300 degree beam angle.
