Mitras Slimline


The Bright LED Lighting for a Perfect Coloring

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

  • Homogeneous, brilliant and very bright light through a balanced mix of selected mid-power LEDs in natural colors (model Skywhite CRI > 95, white LEDs > 150 lm/W)
  • Uniformly wide light distribution with a LED beam angle of 120°
  • Energy efficiency and long LED life thanks to sophisticated heat management (generously dimensioned heat sink and highly efficient heat conducting foil) – LED life at least 60,000 operating hours
  • If controlled by the ProfiLux Aquarium Controller: Professional light dimming (2 channels separately dimmable)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)

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 Slimline (model Skywhite > 95) ensures a brilliant and natural color reproduction.


According to IP 67 – can be used in closed aquariums

High Performance Heatsink

The life time and efficiency (light output per watt) are significantly determined by the cooling. Mitras Slimline 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.

Energy Label

Mounting in the tank

With the supplied stainless steel brackets, Mitras Slimline can be conveniently mounted above every tank.

If there is not enough space in the tank, a flat bracket is also available.

How Many Mitras Slimline do I need for my Aquarium?

Select Mitras Slimline 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 Slimline Skywhite. For luminaires with high blue light component (Ocean Blue, Actinic Blue), the lumen specifications are rather misleading (see explanation above Lumen, LUX and PAR).

Cross-section of light: 62mm x 23mm

*) 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 Slimline light module has an efficiency of about 87%, 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:

Max. Output powerMax. drawn powerPlugInput voltage
20 W23 WEuro100 - 240 V / 50 - 60 Hz
80 W92 WCold device cable (Schuko, CH, UK)100 - 240 V / 50 - 60 Hz

Operation Modes

Mitras Slimline can be operated undimmed and dimmed.

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

Another option, however, is to dimm and operate the Mitras Slimline with a ProfiLux Controller (ProfiLux 3, 4, 4e, Mini, Light a Mitras Slimline Splitter Dimmable required). Both color channels can thus be dimmed independently. So all ProfiLux Controller simulation programs such as sunrise and sunset, cloud simulation, thunderstorms or calendrical moon phase simulation are possible.


  • Undimmed, one power supply per Mitras Slimline
    No further accessories required
  • Undimmed, several Mitras Slimline on one power supply unit
    Using the Mitras Slimline Splitter, up to 3 Mitras Slimlines can be connected to a single power supply. The selected power supply must have at least the total power of all connected Mitras Slimlines.
  • Dimmed, one or more Mitras Slimlines connected to one power supply unit
    With the Mitras Slimline Splitter Dimmable) up to 2 Mitras Slimline can be connected to one power supply unit. The selected power supply unit must have at least the total power of all connected Mitras Slimlines.
    The dimmable splitter has a control input which is connected to the Mitras Lightbar output (or to the RS232 interface on ProfiLux 3) of a ProfiLux. Several Mitras Slimline Splitters Dimmable can be connected to each other if more than 2 Mitras Slimlines are to be controlled.

Mitras Slimline Splitter Dimmable

The Mitras Slimline Splitter Dimmable has two outputs for Mitras Slimline and one output for Mitras RGB (coming soon).

Both LED-strings of each Mitras Slimline as well as all 3 channels (red, green, blue) of Mitras RGB can be dimmed independently, in total 7 channels are separately dimmable over one Mitras Slimline Splitter Dimmable.

There are 2 communication ports: The input port is is used to connect to the ProfiLux Mitras port, the output port can be used to daisy-chain several Mitras Slimline Splitter Dimmable. Since up to 8 devices can be daisy-chained a maximum of 16 Mitras Slimline and 8 Mitras RGB can be controlled from one ProfiLux.

A DIP-switch gives you the option to use channels 1 to 7 (default) or channels 9 to 15 of the ProfiLux to dim the connected lights. When 2 or more Mitras Slimline Splitter Dimmable are used and when they have different channel settings up to 14 LED-channels can be controlled independently.

Please note:

  • The total power of all connected lights must not exceed the maximum power of the used power supply, select the power supply accordingly. If needed use multiple Mitras Slimline Splitter Dimmable to distribute the load between several power supplies.
  • Minimum firmware requirements: ProfiLux 4 / 4e version 7.18, ProfiLux 3 version 6.41, ProfiLux Light / Mini version 1.09
  • Minimum software requirement: GHL Control Center

All updates incl. GHL Connect App, Cloud myGHL and webinterface will be provided in time, before shipments of the Mitras Slimline Splitter Dimmable begin.
