LxBy parameter specifies when the luminaire’s lifetime will expire and how large the margin of error is in its operation. The standard LxBy terminology includes two indicators. The L value indicates the minimum of the luminous flux to be maintained during a certain period of use. The B value indicates the error rate. This refers to the time it takes for y% of the LEDs to reach x% of the initial flux.

What Is the Difference Between Polycarbonate and Acrylic?
Polycarbonate and acrylic are clear plastics commonly used in the lighting industry. Both provide lightness, flexibility, durability and high light transmission. Materials have different strengths and weaknesses against each other. These two types of plastic are often confused with each other as they are similar in appearance.
What Is a Runway Guard Light (RGL)?
Runway guard light (RGL) is a yellow, unidirectional and flashing lighting unit. It is used to warn pilots and vehicle drivers that they are about to enter an active runway. Runway guard lights are installed at taxiway and runway intersections.
How Do Fireflies Glow?
The glow of a firefly is a chemical reaction caused by a compound called luciferin (“light-bringer” in Latin) in the abdomen. Air entering the firefly’s abdomen combines with the luciferin and causes a chemical reaction that emits a light. The uric acid crystals in the cells that make the light carry the light away from the abdomen.
What Is Amber Light Color?
Amber is used to describe a particular hue that lies between yellow and orange. The wavelength of amber light is in the range of 600-615 nm. The color of light starts to turn yellow when the wavelength decreases below 600 nm and orange when it rises above 615 nm.
Do Chickens Need Light?
Light is an important factor influencing the development, welfare and egg production of poultry. Generally, in winter, egg production slows down because there is not enough daylight. During this season, chickens can be provided with artificial light to continue egg production.
What Is Photophobia (Light Sensitivity)?
Photophobia refers to increased sensitivity to light. People with this condition think that normal light is too bright. Photophobia may present as eye discomfort, pain, or an avoidance reaction.
What Percentage of Electricity Is Used for Lighting in a Typical House?
When the electricity bill is high, the biggest culprit is the lights that remain on. It is thought that a significant amount of energy will be saved when the lights are turned off or dimmed. Is it possible to cut the electric bill in half by simply turning off the lights? Short answer; No.
Is Infrared Light Harmful?
Infrared light is basically heat radiation. It has the lowest energy per photon and is the safest type of light. However, when it becomes dense enough, it can damage living tissue. As with most things, the right amount is beneficial, too much is harmful.
