GHL LED Mitras Lightbar 2 Ocean Blue 120-160

The Ultra-Bright High-Power LED Lighting

Mitras Lightbar is one of the highest quality and most effective LED lights on the market. The Mitras Lightbar is Made in Germany and offers:

• Homogeneous, brilliant and very bright light through a balanced mix of selected high-power LEDs in natural colors (CRI> 95, white LEDs 150 lm/W)
• Maximal output power with GHL Power Balancing Technology®
• Super smooth dimming with GHL Perfect Dimming Techology®
• Uniformly wide light distribution with a LED beam angle of 120°
• Energy efficiency and long life through a sophisticated thermal management (at least 60,000 operating hours)
• If controlled by the ProfiLux Aquarium Controller: Professional light dimming, individual mix of the color spectrum and water temperature-dependent downward control (light is dimmed if water gets too warm).
• Full undimmed Lightpower when operated without ProfiLux (all LEDs light up to 100%)
• Energy saving compared with traditional lighting aprox. 50%
• Operation with safe voltage (24V)

Optimal for Every Aquarium

The Mitras light bar is suitable for any marine or freshwater aquarium – if open or closed – and is available in 4 light temperatures in 13 different lengths in 10 cm increments.

Adjust – in conjunction with the ProfiLux Aquarium Controller – the light spectrum (approximately 380-700 nm range) and the light output in wide areas exactly as you like and give your plants, fish and corals the light they need to thrive. The correct light spectrum used is equally as important as the radiation power that can be achieved.

When choosing the Mitras® Lightbar, it is very important to consider how this light will be used; we offer different models to suit different uses. Each model is equipped with special LED combinations perfectly matched for different applications such as Freshwater, upper, medium and deep reef. Of course you can also combine the different models as you like.

Diverse Dimming Functions with ProfiLux

Realistic lighting scenarios such as sunrise, sunset, moonlight, cloud, seasonal lighting and thunderstorm simulations are made possible with GHL Perfect Dimming Technology®. With over 4000 dimming levels and a dimming ratio of 3000:1 per channel (light color), you can accomplish true-to-life simulations.

Ultra Bright

Extremely high luminous output at maximal energy efficiency. Selected high-power LEDs (CREE®, OSRAM®, Semi LEDs®) with at least 150 lumens/watt (white LEDs). The special arrangement of the LEDs over the entire Lightbar length provides a particularly homogenous illumination of the tank.

Special LED Overheat Protection

LEDs are protected by monitoring the operating states of LEDs and of the lightbar temperature. The microprocessor-controlled automatic brightness reduction and the very powerful and massive heat sink ensure efficient and safe operation with maximum light output.

Unique Color Mix

Ideal light spectra for salt and fresh water tanks. The unique light mixing ensures high photosynthetic efficiency for lush growth of plants and corals.

Large Range of Models – Flexible Usage

13 different lengths in 10 cm-increments are available – also for Nano-Tanks – You’ll be able to find the ideal lightbar length for your tank. Illumination over the total tank length provides a maximum light quantity for the tank and avoids only little illuminated corners.
Several Mitras Lightbar can be connected via a splitter to one power supply unit – this way you have less power supply units and less cables in your cabinet.

Available with 4 different LED-combinations (Daylight, Ocean Blue, Actinic, Deep Actinic).

Variable Light Spectrum

Adjust easily the desired light spectrum within a wide range with the Light Composer using the PC Software, GHL Control Center (GCC). Light color and intensity can be varied over the day.

Either you just take over one of the existing lighting projects for your luminaire, or submit your own project.

Brilliant and Natural Light

The high CRI of Mitras Lightbar (> 95) ensures a brilliant and natural color reproduction.

Mitras Lightbar – Luminosity in Detail

Mitras lightbar is not only one of the brightest LED lights on the market. It also convinces by the technical know-how.

Lumen, LUX and PAR – Optimal Conditions with Mitras

LUX (lm / m2) is the unit of illuminance, indicating which luminous flux (lumens) falls on a defined area. The light output lumens (lm) as a measure of the brightness is normalized to the human visual sensitivity. Because humans perceive blue or red light less intense than the green light, the lumen decreases though contstantly high radiation levels the more blue or red the light is.

This is why, the specified lumens at our Mitras Daylight for example, are much higher than in the Mitras Actinic, though the wattage is almost identical.

The qualification of a luminaire only on the basis of lumens / watt (light output per electrical power) is not always appropriate as nothing is said about the photosynthetic efficiency of light

It is quite so that a luminaire with high lumens but unfavorable spectrum of photosynthesis is less beneficial than a luminaire with slightly less lumens but therefor optimum range.

More meaningful is the so-called PAR value (Photosynthetic Active Radiation), which describes the available radiation for photosynthesis.

All this offers the high-power Mitras LED illumination in perfection. Mitras Luminaires achieve above-average PAR values and thus ensures healthy growth in your aquarium.

Suitable Light Spectrums for Specific Applications

For an optimal lighting result, we offer four different types with different LED combinations to choose from:

• Mitras LB Daylight (Freshwater with many plants)
• Mitras LB Ocean Blue (Freshwater and Salt Water)
• Mitras LB Actinic (Saltwater upper to medium reef)
• Mitras LB Deep Actinic (Saltwater medium to deep reef)

They differ in terms of the average color temperature and are tailored to the specific application.

If operated with the ProfiLux Aquarium Controller the offered selection of several LED colors gives the opportunity to adjust the light color via GCC within far bounces. However the Luminaires should be chosen in a way that the average light color matches as good as possible. The higher the light temperature is, the more bluish the light appears.

How Many Mitras Lightbar do I need for my Aquarium?

Select Mitras Lightbar depending on the aquarium volume.

Rule of thumb:

• low light requirement: 0.3 watts per liter
• very high light requirements: 0.9 watts per liter

Often, a recommendation “lumens per liter” is given. In our opinion this makes only sense for Mitras Daylight. For luminaires with high blue light component (Ocean Blue, Actinic, Deep Actinic), the lumen specifications are rather misleading (see explanation above Lumen, LUX and PAR).
