LEDs are a simple invention with huge potential to change the lighting industry for the better. Don’t know much about them? Here are the big things you need to know. LED Lights.
How many lumens does an LED light bulb require to replace incandescent bulbs?
How do LEDs work?
Unlike traditional incandescent bulbs, LEDs don’t have filaments inside that heat to glow the bulb. The LED bulb has a P-N arrangement of two side assortment where one side contains positive electrons and the other side has a negative charge. When the current flows on these sides in a certain amount of voltage, both charges combine to release energy in the form of light. Thus, the light we witness coming out of the bulb is an LED light.
Why are LEDs recommended?
LEDs are an essential lighting choice that provides illumination with various advantages such as energy savings, lifespan, environmental friendliness, and various other advantages. LEDs are a fantastic choice over traditional lighting fixtures since they do not generate excessive heat when blazing, spend less energy, have appropriate wattage equivalence, etc. Although LED bulbs are more expensive than CFLs and incandescent lights, the advantages outweigh the costs.
With so many LED light options available, you may use these bulbs in practically any situation. The lighting provided by the bulbs is superb, and the light has a good range.
Terms used in LED lights
What is Lumens?
Lumens are units of measurement for a bulb’s light output capability. It is critical to check the lumens before purchasing a bulb. You must first determine how many lumens are necessary for your site and select the appropriate watt fixture.
What is a foot candle power (Fc)?
foot-candle is the SI unit of light intensity. The lumens that reach the surface per unit area with a specific light source are measured.
What is Kelvin?
Kelvin is the temperature of the color appearance of the light and is used to measure the CTT (correlated color temperature) of a light. In the case of LED lights, the color temperature indicates how the light’s color will distribute in the surroundings. The color temperature of light can vary depending on the temperature.
2700K-3500K – Soft/warm white light: A Soft or warm white light seems yellowish.
3500K-4500K – Natural white: These color temperatures produce an off-white hue of light. The light has a little yellow tint to it.
5000K – Daylight white: In the daytime white color temperature band, the light emits a somewhat blue tint. The light, which is often appropriate for larger outdoor settings, can effectively assure visibility in the region.
5500K – 6000K – Cool white: The intensity of the emerging blue tint is considerably stronger in these color temperatures. Because it is a commercial standard color temperature, the light is not suitable for use in the home.

The greater the color temperature of an LED light, the broader its application area must be. Warm white light temperatures, for example, are appropriate for residential uses, but daylight white or cold white light temperatures are preferable for larger outside applications such as parking lots, streets, lanes, gardens, and so on.
The most common color temperature for LED parking lot lights and LED pole lights is 5700K, which provides enough lighting between the daylight and cool white lite contexts.
What is CRI?
CRI is an abbreviation for color rendering index, which indicates how objects appear in human eyes in the presence of light. The spectrum represents the influence of light and how well it can depict items in their natural/actual hues.
LED parking lot lights and LED pole lights are examples of efficient outdoor lighting installations that require a high level of illumination. As a result, its CRI is purportedly higher since it assures that the light is visible in the dark.
What is Lumen efficiency?
lumen efficiency, measured in Lumens per Watt, reveals how effectively the light source disperses its lighting. A 100 Watt bulb with a lumens output of 1500 lumens, for example, will have a luminous efficiency of 15 Lumens per Watt (1500/100 = 15).
What is 0-10v dimming?
0-10v dimming capability assures that the LED light may execute the 3-step dimming function. You may modify the brightness of the light in this feature based on your preferences and the requirement of the place. This dimming helps you to conserve energy and money.

The origin of LEDs
What is an LED?
LED stands for light-emitting diodes. These are the small chips on a semiconductor strip or plate through which current passes to light the microchips or bulbs.
What is a light-emitting diode?
Light-emitting diodes are the small bulbs on a semiconductor chip that shine when current runs through them, as previously discussed. Because of their nature as diodes on a circuit board, they require constant power to convert alternating current to direct current power.
