Latest Technology
The state-of-the-art Chip On Board (COB) light engine is the most critical component in the luminaire assembly and responsible for the majority of the lighting attributes.
Ark Licht / Mracek uses the highest quality commercially available chips in the D-Series. These premium chips ensure that the light is vivid, efficient, natural and consistent.
Natural Light
D-Series luminaires produce white light with a full colour spectrum similar to that of the sun, resulting in a very natural, accurate and comfortable environment.
Wavelengths between 380 - 400nm (Ultraviolet) & 700 - 780nm (Infrared) are produced with minimal intensity, both eliminating harmful light and saving energy. The visible colour spectrum for humans is about 400 - 700nm.

Vivid Colours
CIE 13.3-1995 (CRI): The standard for measuring colour rendering since 1965 and the most widely adopted standard in the industry, representing 15 common colours rated on a scale up to 100 (an ideal and accurate representation), with no lower limit.
Ark Licht / Mracek's Ultra High Colour Rendering Index (CRI) ensures that the colours in your space appear vibrant and natural.
R9 (deep red) is the most critical colour as it is responsible for the accurate appearance of skin tones as well as most natural objects. It is also the most difficult colour for any LED light source to render.

Ra ≥ 97
Re ≥ 95
R9 ≥ 92
Next Generation Light Quality
TM-30-20: The latest colour rendering standard designed to address the shortfalls of CRI.
Rf - Fidelity Index: An average (from 0 - 100) of your light's comparative ability to accurately render all 99 colour samples (hue).
Rg - Gamut Index: Characterises your light's saturation accuracy of the samples; an ideal value is 100.

Rg = 100 +/-2
Picture Perfect
Capturing what we see and experience has become an important part of our lives. The capabilities of cell phones and cameras are improving at a fast pace but even the best sensors can only record the information that is available. Dull or missing colours can make your images look lifeless and can be time-consuming or impossible to correct through editing.
TLCI-2012 ≥ 98
Colour Consistency
3-step MacAdam colour consistency or SDCM (Standard Deviation of Color Matching) ensures that any colour variation between luminaires is indistinguishable to the human eye, resulting in a uniformly lit environment.

Color consistency ≤ 3 SDCM
40º Light Angle
The most versatile beam angle - ideal for a large variety of applications.
Designed to achieve the perfect balance between reflective characteristics and low glare.
Unified Glare Rating (UGR) ≤ 19
Water Resistant
An IP65 rating gives you the flexibility to use the D-Series in wet environments since it can come into direct contact with water.
Water Resistance (room side) - IP65
Passive Heat Control
The heatsink is one of the most important components responsible for ensuring a long and reliable life of the light. Carefully designed using Computational Fluid Dynamic analysis to passively draw as much heat away from the COB while maintaining the smallest form factor. Constructed from Die Cast Aluminium for it's superior thermal and mechanical properties.
No Tools Required
Fast, easy & reliable installation using spring retainers.
Grouping
Recessed lights can be configured to include up to 4 luminaires/driver, resulting in a simplified installation and up to 17% in price savings.
IMPORTANT: The maximum distance between the driver and the luminaire should not exceed 2m.
Never connect less than the specified amount of luminaires. For example, if you purchase 4 luminaires/driver, never connect the driver to electricity if there are less than 4 luminaires connected to the driver. This will result in an overload and may destroy the luminaires and/or driver.
Tridonic Ballast
All luminaires are equipped with high quality, external Tridonic ballasts guaranteeing the best possible performance and reliability.
Non-Dimmable: Tridonic LC Series
Dimmable: Tridonic LCA Series
Total Control
Dimmable with most leading and trailing edge LED dimmers to adjust the brightness for a specific task or mood.
Peace of Mind
Warranty
5 years / 50.000 hrs warranty when installed and used correctly.
CE, RoHS & RCM
