  • 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.

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.

Outstanding Light Performance

  • Selected high-power LEDs from Cree® (e.g. XPG3, XPE2, XTE), OSRAM® (Oslon SSL) and SemiLEDs® of the newest generation (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 is set via the free 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

Photosynthetic Efficiency with Mitras Luminaires

With the help of light energy from CO2 and water, coral symbionts and plants build carbohydrates and and discard oxygen; this process is called photosynthesis. In charge of this energy production is the plant pigment chlorophyll (a + b and carotene).

Light beams can be understood as electromagnetic waves, which are made of energy particles called photons. The energy of the so-called Photon is dependent on its wavelength (nm) and its frequency (THz). Different wavelengths of light we see as color. The visible light by humans covers only a certain segment of the electromagnetic spectrum which moves in the range of 380-750 nm.

As you can see – For the intended use, a suitable light spectrum and light intensity are crucial for the photosynthetic activity of coral symbiont and plants. The higher the photosynthesis rate is, the stronger and healthier growth could be achieved.

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.

More Facts why Mitras Luminaires are Your Best Choice

When comparing our Mitras Luminaires with others, you should note the following points:

  • Our electric power includes also the consumption of the control electronics, not only the consumption of the LEDs.
  • The light performance indicated by us includes also the performance of the LEDs which contribute less to the creation of lumen but which optimize the spectrum.
  • Furthermore, we indicate the actually remaining lumen after deducting the losses through the glass and temperature increase.
  • Contrary to the commonly used practice to use cheap series resistors for LED-current limiting, in our luminaires the current of LEDs is precisely controlled by electronics. This reduces the current consumption and waste heat.
  • We truly believe that we could utilize the maximum out of LED-technology – the best LEDs, an extremely transparent protector plate, a massive cooling and an electronic control. More is hardly possible. If you find elsewhere better performance data, then you should question this critically.
  • We don’t indicate any ideal theoretic values, but the performance data which can be reached in practice after deduction of all losses.

Photosynthesis with Mitras Lightbar Daylight in freshwater 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 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).

Operation Modes

Mitras Lightbar can be operated undimmed and dimmed.

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

Another option, however, is to dimm and operate the 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.
