LED

In recent years, LED lighting has been developing extremely fast and has replaced traditional lighting fixtures. High-quality fixtures have many advantages, such as energy efficiency and long lifespan.

At present, with a well-constructed fixture with completely transparent polished glass, the light output is about 130 Lm/W. If the glass is frosted or white, the brightness drops by 20 to 50%, and it becomes around 100 Lm/W to 60 Lm/W. Any obstruction in front of the LEDs, including different types of optics, reduces the total brightness. This means that if an LED bulb or tube is placed into a different housing, the overall brightness drops an additional 15 to 50%. The most important indicator for a lighting fixture is the brightness, which is measured in Lm, not the power it consumes, which is measured in W. Just because a fixture is more powerful doesn’t mean it lights up more; it only consumes more power. Other important indicators include the Color Rendering Index (CRI), which should be above 80. If the CRI is lower, the perception is unpleasant, and the color temperature should ideally be up to 4000K, as temperatures above 4000K can be harmful to vision. The reliability and lifespan of a lighting fixture depend heavily on cooling. We design LED fixtures to work at up to 55°C ambient temperature, as this is typically the temperature that the upper part of a room reaches. All our LED fixtures are made with reinforced radiators — minimum 50mm²/W — which ensures cooling and long life for the fixtures. Very often, lighting fixtures are made with pulse power supplies that need the surrounding temperature around the power supply to be up to 50°C in order to operate continuously. This means that if the power supply is mounted in a lighting fixture, the temperature around the fixture must be up to 30°-35°C; otherwise, its life will decrease rapidly.

It is important to note that with lighting fixtures from the Far East, the brightness stated on the label often differs from the actual brightness, with the difference being up to three times. The radiators for cooling are 2 to 5 times smaller than required, leading to the rapid degradation of the LED and a reduction in the light flux by up to four times within one year.

A common approach is to only replace the bulbs or fluorescent tubes. Although this may seem easy, it’s usually not a very good approach, especially with tightly sealed fixtures, as proper cooling is not provided, and the life of the lighting fixture decreases significantly. Additionally, the extra plastic lampshade also reduces the total brightness. Many times, lighting fixtures are selected based on the lowest cost per watt. These fixtures operate with components outside of their nominal values, leading to a sharp reduction in the lifespan of the fixtures — 20 to 50 times shorter.

In the electrical materials sector, which includes cables, equipment, switches, sockets, etc., there are clearly defined rules and requirements (operating temperature, heat dissipation of the housing, overheating, etc.), which unfortunately are lacking in LED lighting. As a result, the entire lighting sector, including many products from leading lighting companies, has become a problem.

All our lighting fixtures are made with aluminum housings and integrated diodes for better cooling and durability. The power supply is composed only of passive components, which provides a service life of 50,000 hours. The fixtures are designed similarly to the analogs they replace and are constructed for easy installation.

Our goal is to create reliable, functional, affordable, and aesthetically pleasing lighting fixtures.

Color Rendering Index (CRI) and Color Temperature

The color rendering of light sources is an indicator of their ability to reproduce the colors of an object realistically. The Color Rendering Index is indicated by CRI.

Color temperature is measured in Kelvin (K). A low color temperature of 2800-3000K creates a warm and cozy effect, 4000K is neutral and the most versatile, while a high color temperature of over 5000-6500K creates a cold light effect.

Defining several groups to make it easier to compare color rendering quality:

Color Rendering

The maximum CRI value of 100 corresponds to daylight. According to studies, lighting with a CRI over 75 allows for realistic color perception, while lighting with a CRI below 65 does not. When buying an LED product, choose one with a CRI of 80 or higher. Studies show that a color temperature between 2800-4000K is best for urban lighting systems and residential use. Lights with color temperatures of 5000-6000K are suitable only for advertising lighting. If used in residential or industrial spaces, they can be harmful to eyesight. The Color Rendering Index and color temperature are some of the most important factors in lighting for your home, office, or other space. They determine whether the lighting will strain your eyes, whether the space will be well-lit, and even how you will feel emotionally.
