Glamox aims to sell LED luminaires with single LEDs, LED modules and LED drivers with the best possible quality. We also strive to provide customers with the quality they want, nothing more, nothing less. By doing this, we provide a good cost/benefit ratio to our customers.
Our engineers are among the world’s leading experts on LED technology
We use their expertise to design and manufacture innovative products with low energy consumption and long life. Equally important is our experience and know-how about the design of optics and thermal control, so that the products will perform to standard over a long period of time.
We always use the best quality LEDs for our purposes, from the best manufacturers.
Particular attention is given to the colour temperatures and colour rendering qualities of the LED light sources we use.
High power LED’s require more precise current and heat management than traditional light sources. Our know-how of thermal control has significant influence on the life span of our products.
Products with LED often have problems meeting glare requirements. Our engineering skills ensure that our products with LED always meet or exceed relevant national and international standards.
One of the advantages of LED is that all the light is emitted in one direction. This entails fewer reflections inside the luminaire since we normally want the light to go downwards only. If we need a light distribution that goes both up and down, the LED is less suitable compared to e.g. a T8 fluorescent lamp.
Conventional light sources cast a lot of light backwards, which may be lost in the optics design of a luminaire. The LED, on the other hand, emits all light in one direction.
One of the benefits of the LED is its long lifetime. Because they have no movable parts or filaments that may break, LED's can have long lifetime.
The light output from all light sources, LED, halogen, metal halide and fluorescent decreases over time. The amount of light from the light source at a specific time in the future is referred to as the lamp lumen maintenance factor, or LLMF. The lifetime of a LED module is defined as the time it takes until its light output, or lumen maintenance, reaches 70% of the initial output. This is also called L70. In other words, the module does not die instantly as many conventional light sources do, it slowly dims down. Lighting planners take this effect into account when they dimension the lighting installation. As they want the light level to reach a minimum lux value at the end of the lifetime, they over-dimension the luminaire installation, often by using more luminaires. Therefore, the lux value in the beginning of the operating life of the lighting installation is higher than what it is at the end. The luminaire industry has standardised LED lifetime to L70 = minimum 50000 hours, which corresponds to an LLMF of 0,7 as long as the lifetime of the lighting installation is set to the same amount of hours.
For some of Glamox LED products, the lumen degradation is better than the industry standard. After 50000 hours of life, not only 70% of the life remains, but 80% or even more. The LLMF is then raised to 0,8 or above and the lighting designer does not need to over-dimension the lighting installation as much. With this upgrade, up to 25% of the luminaires may be left out, depending on the ceiling type. That means lower installation costs and a lower energy bill. At the same time, the lux levels are always meeting the lighting norm requirements. In our datasheets this is shown as Lx = 50 000 hours at 25 deg ambient temperature (Ta).
