Optimal for Every Aquarium

The Mitras Lightbar is designed for use in open and closed (canopy) environments and is suitable for any marine or freshwater aquarium. Available in 4 light temperatures and 13 different lengths (in 10 cm increments), you can mix and match different options to suit your specific needs.

Get the desired light output in your aquarium: With Mitras Lightbar there is no compromise by only a few offered lengths, forget badly illuminated corners in the aquarium.

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.

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 barely 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 (model Daylight > 95) ensures a brilliant and natural color reproduction.

Waterproof

According to IP 67 – can be used in closed aquariums.

High Performance Heatsink

The lifetime and efficiency (light output per watt) are significantly determined by the cooling. Mitras Lightbar therefore have a massive heat sink that ensures maximum cooling of the LEDs.
The screw channel at the top of the heat sink provides additional mounting options, such as the use of suspension sets.

Outstanding Light Performance

  • Selected high-power LEDs from Cree®, OSRAM® and SemiLEDs® of the newest generation (min. 150 lumens/watt white LEDs) with optimal color mixing and uniform illumination.
  • Lifespan > 60,000 hours according to manufacturer
  • CRI >95
  • The LEDs are intentionally not operated with the maximum possible current, since this significantly reduces the LED life and energy efficiency. It is much more efficient to use a larger number of LEDs at reduced power.

Uniform Light Distribution

  • Ideal mixture of the individual LED colors. The light generates no disturbing color spots in the aquarium.
  • The particularly translucent protective plate made of XT UV Transmitted® guarantees optimum light yield and uniformity. This special acrylic is also used for solariums and has a very high transmission for a wide light spectrum.

Innovative Cooling System

  • Passive cooling through generously dimensioned solid aluminum heatsink with seawater resistant anodized aluminum coating in accordance with DIN 81249-1.
  • Microprocessor-controlled automatic brightness reduction at high Lightbar temperatures. Increases the housing temperature of the Lightbar further, eg due to increased ambient temperature, the brightness is reduced slowly and continuously.
    The electronics and the LEDs are thus always operated under optimal conditions.
    Thanks to the mild operating a high energy efficiency a very long LED lifetime can be achieved.

Operation, Dimming and Equipment

Operation:

  • With Mitras LBSplitter (not supplied) and the matching power supply unit (not included) simultaneous operation of up to 4 light bars is possible.
    Due to the manifold operation options we offer a variety of power supplies. Note that the selected power supply must provide the total power of all connected Lightbars at least.
  • Mitras Lightbar is available in 13 lengths and four models in 10 cm increments.
  • For flexible installation in the aquarium slidable holders made of V4A stainless steel are included.

Dimming:

The Lightbar can be operated undimmed (all LEDs at 100%) and dimmed (with the aquarium computer ProfiLux from version 3). For connection to the ProfiLux Computer additionally an interface cable is required.

All LED channels (depending on model 5 or 7) are separately, this allows you to vary the light color and intensity of illumination over the day. The GHL Perfect Dimming Technology® with more than 4000 dimming levels and a dimming ration of 3000:1 produces a super soft and perfect dimming.

The light spectrum can be easily set via the GHL Connect APP, the Cloud service myGHL and the free  PC software GCC. Thus, the following lighting scenarios can be realized via the ProfiLux Controller:

  • Sunrise and Sunset
  • Cloud Simulation
  • Thunderstorm Simulation
  • Calendric lunar-cycle Simulation
  • Seasonal Lighting > Learn More
  • Rainy Days

Equipment:

  • Replaceable LED Clusters.
  • Waterproof*) efficient wide range power supplies (IP 67) with all relevant marks of conformity (eg CE, TÜV, UR)

Dimensions: h x w = 25 mm x 86 mm

*) except 60W

Mounting in the tank

With the supplied stainless steel brackets, Mitras Lightbar 2 can be conveniently mounted on top every tank.

For tight space, e.g. under an aquarium canopy, optional flat brackets are available.

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 recommendationlumens 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).

Cross-section of light: 86mm x 25mm

*) This is the net power draw of the light module. If you compare it with the power of LED lights from other vendors you should keep in mind that they often only mention the higher power draw of the complete system, including the loss of the power supply.
Also the efficiency (ratio between electrical power and light power) is very important when comparing. The Mitras Lightbar light module has an efficiency of about 92%, where most LED lights of other vendors have only an efficiency of about 75%.

Power supplies

To save space and costs, several luminaires can be operated via a splitter on one power supply unit. Please note that the luminaires are therefore supplied without a power supply unit. Please order the appropriate power supply unit for your luminaires separately. See the Configurations section below.

The following power supplies are currently available:

Operation Modes

Mitras Lightbar can be operated undimmed and dimmed.

If operated undimmed all LEDs will be operated at 100%. There is no control needed. Activation and deactivation can be made through a simple timer.

Another option, however, is to dim and operate the Mitras Lightbar with a ProfiLux Controller (starting version 3). All color channels can thus be dimmed independently. So all of the ProfiLux Controllers simulation programs such as sunrise and sunset, cloud simulation, thunderstorms or calendrical moon phase simulation are possible.
