Smart Lights FAQs: The Parameters of Smart Lights


In our last blog post, we introduced you to the basics of smart lighting. We explained what it is and how it works. In this blog post, we will answer some of the most common questions that people have about smart lighting. Keep in mind that this is just a general overview – for more specific information, please consult your light fixtures’ user manuals.

What are lumens?

Lumens are a unit of measurement for the quantity of light released by a light source. The higher the lumen rating, the more brilliant the light. Lumens are utilized to determine both artificial and natural light sources’ brightness. Lumens are measured in lm.

What is Lumen Effeciency?

Lumen efficiency is a measure of how well a light source produces visible light. The higher the lumen efficiency, the more visible light is produced per unit of energy used. Lumen efficiency is important for both energy efficiency and light output. Higher lumen efficiency can reduce energy costs and increase the amount of light produced. The unit of luminous efficiency is Lm/W.

What’s the relationship between Lumen & Lumen Effeciency?

In a short word, Lumen efficiency(Lm/w) = Lumen(Lm) / Power(W)

What is a lux?

A lux is a unit of measurement for the intensity of light. It is defined as the luminous flux per unit area. Lux can be used to measure both natural and artificial light sources. The higher the lux, the brighter the light. Lux is measured in lx.

What does CCT mean?

CCT, or color temperature, is a way of describing the light appearance from a light source. It is measured in Kelvin and is typically found between 2200K and 6500K. The lower the CCT, the warmer the light will appear. The higher the CCT, the cooler the light will appear.

What is CRI?

CRI, or Color Rendering Index, is a measure of how accurately a light source can reproduce the colors of objects it illuminates. The higher the CRI rating, the more realistic and accurate the colors will appear.

What is RGB?

RGB is an acronym for red, green, and blue. RGB is a color model that uses three primary colors to create all other colors. These three colors can be combined in various ways to create different shades and tints. RGB is used in digital imaging and video applications

What is RGBW?

RGBW is short for Red, Green, Blue and White.
