Mitras Lightbar 2

Choose from 2 colors

Mitras Lightbar 2 is available in Silver/White and classic Black.

Perfect Lighting for Every Aquarium

The Mitras Lightbar 2 is designed for both open and closed (canopy) aquariums, making it the ideal choice for marine and freshwater environments alike. With four different light spectrums and 13 length options (available in precise 10 cm increments), you can mix and match to achieve the perfect fit for your setup—eliminating dark corners and ensuring even illumination throughout your aquarium.

Paired with the ProfiLux Aquarium Controller, the Mitras Lightbar 2 allows you to fine-tune the light spectrum (380–700 nm range) and adjust brightness to meet the exact needs of your plants, fish, and corals. Achieve optimal photosynthetic efficiency with the right light spectrum and radiation intensity, ensuring a thriving aquatic environment.

To maximize performance, choosing the right Mitras Lightbar model is essential. Each version is equipped with specialized LED combinations tailored for different applications, including Freshwater, Shallow Reef, Mid-Depth Reef, and Deep Reef. Want even more customization? Combine different models to create the perfect lighting solution for your unique aquarium.

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.

Advanced Dimming Functions with ProfiLux

Bring your aquarium to life with realistic lighting scenarios like sunrise, sunset, moonlight, clouds, seasonal changes, and even thunderstorms—all made possible with GHL Perfect Dimming Technology®. With over 4000 dimming levels and an impressive dimming ratio of 3000:1 per channel, you can achieve smooth, natural transitions that perfectly replicate real-world lighting conditions.

Ultra-Bright Illumination

Experience exceptionally high luminous output with maximum energy efficiency. The Mitras Lightbar 2 is equipped with carefully selected high-power LEDs from CREE®, OSRAM®, and Semi LEDs®, delivering at least 150 lumens per watt (white LEDs). Thanks to the strategic LED arrangement along the entire length of the Lightbar, your aquarium benefits from uniform, shadow-free illumination for a natural and vibrant look.

Advanced LED Overheat Protection

Your LEDs stay protected with continuous monitoring of both operating conditions and lightbar temperature. A microprocessor-controlled automatic brightness reduction prevents overheating, while the powerful and robust heat sink ensures efficient cooling. This guarantees maximum light output, long-term reliability, and safe operation even under demanding conditions.

Unmatched Color Mixing

Perfectly optimized light spectra for saltwater and freshwater aquariums. The unique LED blending technology ensures high photosynthetic efficiency, promoting lush plant and coral growth while enhancing the natural beauty of your aquarium.

Large Range of Models

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 aquarium. Illumination over the total aquarium length provides a maximum light quantity for the tank and avoids only barely illuminated corners.
Several Mitras Lightbar 2 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).

Customizable Light Spectrum

Easily adjust and fine-tune your light spectrum with the Light Composer in the GHL Connect App or in the GHL Control Center (GCC) software. Modify both light color and intensity throughout the day to perfectly match your aquarium’s needs.

Choose from preconfigured lighting projects for instant optimization or create your own custom lighting schedule for a truly personalized experience.

Exceptional Color Rendering

The high CRI of the Mitras Lightbar 2 (Daylight model >95) guarantees brilliant, true-to-life color reproduction, making your aquarium look as natural and vibrant as possible.

Waterproof & Versatile

With IP67 protection, the Mitras Lightbar 2 is safe for use in closed aquariums, offering reliable performance even in high-humidity environments.

Optimized Cooling for Maximum Performance

The lifespan and efficiency of an LED depend heavily on proper cooling. That’s why the Mitras Lightbar 2 features a massive heat sink, ensuring optimal heat dissipation and maximizing LED performance and durability.

For added versatility, the integrated screw channel on top of the heat sink allows for easy installation options, including suspension kits for flexible mounting.

Mounting in the tank

With the supplied stainless steel brackets, Mitras Lightbar 2 can be easily mounted on any aquarium.

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 2 Daylight (Freshwater with many plants)
• Mitras LB 2 Ocean Blue (Freshwater and Salt Water)
• Mitras LB 2 Actinic (Saltwater upper to medium reef)
• Mitras LB 2 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 Lightbars 2 Do I Need for My Aquarium?

Choose the right Mitras Lightbar 2 based on your aquarium volume and the light requirements of your setup.

Rule of Thumb:

• Low light requirement: 0.3 watts per liter
• Very high light requirement: 0.9 watts per liter

Many sources recommend using lumens per liter as a guideline. However, we believe this only applies to Mitras Daylight models. For luminaires with a high blue light component (such as Ocean Blue, Actinic, and Deep Actinic), lumen values can be misleading due to the way light perception differs across spectrums. (See explanation above: Lumen, LUX, and PAR.)

*) Understanding Power Consumption in LED Comparisons

When comparing Mitras Lightbar 2 to other LED lights, keep in mind that many manufacturers only specify the total system power draw, including power supply losses. A more accurate comparison looks at net power draw—the actual energy consumed by the light module itself. Additionally, efficiency plays a crucial role:

• Mitras Lightbar 2 achieves an efficiency of ~92% (ratio of electrical power to actual light output).
• Many other LED lights on the market only reach ~75% efficiency.

This means that Mitras Lightbar converts more energy into usable light, delivering superior performance with lower power consumption.

Power Supplies

To save space and reduce costs, multiple Mitras Lightbars 2 can be operated from a single power supply unit using a splitter.

Important: For this reason, luminaires are supplied without a power supply unit. Please make sure to order the appropriate power supply unit separately based on your setup. See the Configurations section below for details.

The following power supplies are currently available:

Operation Modes

Mitras Lightbar 2 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 2 with a ProfiLux Controller (starting version 3) for independent dimming of all color channels. This enables the ProfiLux Controllers advanced simulation programs and unlocks the full potential of natural lighting effects including sunrise and sunset, cloud simulation, thunderstorms or calendrical moon phase simulation.
