Zhaga compatible LED modules and arrays allow for the upgrading and servicing of luminaires, future-proofing them for innovations in the lighting industry and beyond. The LumiBar is compatible with Zhaga Book 7.
(HIDE ADDITIONAL INFO)Zhaga Book 7 defines a family of 18 linear and square LED modules suitable for indoor lighting applications (READ MORE)

LumiBar LED modules can be ordered in standard Zhaga Book 7 lengths of L28 (280mm) and L56 (560mm). To provide installation flexibility, lengths of 70mm and 140mm are available. The standard W2 (20mm and 24mm) and W4 (40mm) widths are also respected.
(HIDE ADDITIONAL INFO)LumiBar LED modules, designed and built in our production center in Germany, embody precision and innovation that bring your visions to life with cutting-edge LED technology.
Our "Build Your Own" LumiBar Zhaga LED modules can be tailored to your project's specific needs including light characteristics, intensity, dimensions, connections, and systems, ensuring a perfect match for your requirements.
Light characteristics of LumiBar can be defined in terms of CRI from 70 to 99 and color temperature from 1800K to 7800K.
Such extensive choice is made possible by the best quality, most competitive LEDs from the leading manufacturers, such as Nichia, Cree, Samsung, or Seoul Semiconductor. Our "Build Your Own" LumiBar LED strips will always use the latest version of these LEDs.
Light intensity of LumiBar LED strips is determined by the number of LEDs per strip. Choices include low density (28 LEDs for LumiBar 560mm), medium density (48 to 52 LEDs) or high density (up to 72 LEDs).
LumiBar is available in the most common standard dimensions: L28W2, L28W4, L56W2, L56W4 (READ MORE)
The most common Zhaga Book 7 LED module dimensions are:

The Nichia LED quality
The Japanese company Nichia, our recommended choice for the LEDs used on LumiBar strips, is the world leader in the LED market, with a market share of over 25% and the longest experience in the field. Nichia is the inventor of the white LED production technology, receiving the Nobel Prize for this invention.
The very long life of Nichia 757 LEDs (minimum 100,000 hours), exceptional luminous efficacy, superior light output and spectrum qualify our LED strips for long-term use even for the most demanding applications.
The difference between the quality and performance of the LumiBar strip with Nichia LEDs and a low-cost LED strip, is evident from the first light, and in time the gap increases even more.
1. Longest-lasting light: Nichia LEDs last 90% longer

After 10,000 hours of operation, a Nichia 757 LED keeps 97% of the initial luminous flux, under high operating conditions, shining like in the beginning, while 90% is maintained even after 60.000 hours.
In most applications, this translates into an effective 100,000 hours lifetime or 10 years of continuous operation in a shopping center, decades of operation in a home.
In contrast, a low-cost LED loses up to 60% of the initial value in less than 10,000 hours, approximately one year of operation. It becomes too weak for the initial purpose in just 1,000-3,000 hours.
The evolution of light output for the Nichia 757 LEDs is demonstrated by 10,000 hours of testing, according to the LM-80 standard. Lifetime (light at 70%, 80% and 90%) is calculated using TM-21, both internationally recognized standards and used by all major manufacturers.

2. More light for less power: Nichia LEDs are 65% more energy efficient

The design and material quality influence the luminous efficacy and the LED light output. Nichia 757 LEDs have the highest luminous efficacy on the market, more than 230 lumens per watt, compared to a low-cost LED that has less than 80 lumens per watt.
The difference of more than 65% in luminous efficacy is outstanding when seen in practice. After a cove light retrofit from low-cost LED strips to Nichia LED strips, the illumination increased by three to five times for the same power consumption:

3. Uniform white light: Nichia 757 LEDs are color temperature sorted
By implementing the 3 Macadam Elipse sorting standard in our manufacturing, ensures that Nichia LED strips for a project will have the same white color temperature. Uniformity is also be maintained for future projects.
In contrast, low-cost LED strips are not manufactured with the Macadam Elipse sorting standard, being delivered with many different color temperatures of white. Often, differences are even on the same reel. Moreover, after just a few thousand hours, the low-cost LEDs change their color temperature, resulting in a rainbow effect with yellow and blue hues.
After a cove-light retrofit from low-cost LED strips to Nichia LED strips, the importance of the 3 Macadam Elipse sorting standard is clear.

4. Natural light spectrum: Nichia 757 LEDs have CRI up to 99
Nichia LEDs, with CRI up to 99, reproduce colors as naturally as possible, closely matching the spectrum of sunlight. This capability ensures that colors are rendered accurately and vividly, enhancing the visual experience in any application
Low-cost LEDs only have a maximum CRI of 80, their light distorting color shades, especially warm colors, such as red, orange or brown.

LumiBar 56W2 LED strips can be combined with profiles to provide compact and powerful luminaires. The quality of the materials is excellent, as are the finishes, the profiles in our offer have the quality for the German market.
