A light-emitting diode (LED) is the latest technology in energy efficient lighting. It has such advantages as low power consumption, high energy efficacy, low working temperature, high lifespan and high light quality. Today, LED technology has fully replaced all the other lighting devices by also being a low costing manufacture and service. Now MJ-light provides all the product with LED modules or make them available for using LED lamps.
A color rendering index (CRI) is a measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source. The higher index the higher color rendition. According to the European Regulation all LED lamps, lights and modules used in interior areas must have a Color Rendering Index greater than 80. The color Rendering Index greater than 65 is required for exterior applications. All our LED modules have CRI more than 90.
The color temperature is separated into three groups:
-dw – daylight white (> 5300 Kelvin)
-nw – neutral white (3300 – 5300 Kelvin)
-ww – warm white (< 3300 Kelvin)
It is important to take into account the color temperature of illumination. A warmer (a lower color temperature) light is often used in public areas to promote relaxation, while a cooler (higher color temperature) light is used to enhance concentration, for example in schools and offices. Warm light is better fit for houses and apartments.
Not all LED lamps are dimmable. You need special type of a lamp, which works with your type of dimmer. We provide special dimmable drivers that fit almost all types of dimmers. Our customer service can assist you, if you have any questions.
The most popular types of LED modules are SMD (Surface Mount Diode) and COB (Chip on Board). They both produce high quality light, have high lifespan and are very efficient. COB downlights provide a better light source. It achieves more focused light and the light beam can be controlled by using reflectors. Due to the clear lenses, more light can penetrate further which means they perform well in rooms with high ceilings.
SMD downlights produce a wide spread of light. It floods light everywhere which in turn means there is a higher glare. Their wide beam angle is suitable for larger rooms. In our product we use both types of LED chips for different applications.
The Unified Glare Rating helps to determine how likely a luminaire is to cause discomfort to the people. This classification ranges from 5 to 40 where low numbers indicate low glare.
Glare can be a common issue in workplaces. Inappropriate luminaires cause excessive brightness to be “bounced off” reflective surfaces, such as computer screens, whiteboards etc. This can cause disruption for the occupants of offices in terms of headaches & eye problems, which can later lead to employee absences. When we develop our product, we take it all into account. Construction of luminaries, reflectors and lenses make glare effect as less as possible for each product.
The IP Code, sometimes interpreted as Ingress Protection Marking, classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and moisture in mechanical casings and electrical enclosures. IP consists of two digits. First digit shows protection from intrusions. Second digit shows protection from water, moisture and water drops. The higher digit the stronger protection. For exterior usage IP protection must be higher than 44.
