Discover the ultimate illumination: POLAR at 7500K for natural, cool white-blue light and MARINE at 13000 Kelvin for icy, high-blue light. Ideal for specialized underwater scenes and striking depth or cave effects.
Next Generation of Lighting with Heat Recovery
Professional Lighting for Aquariums and Terrariums: Our PRO² LED bar offers the perfect lighting solution for your underwater worlds. With its double-row LED configuration, it significantly outperforms the eco+ version in terms of light output. The highlight: Two distinct light colors per row, which can be controlled separately. This allows for striking day simulations. One product, two light colors for atmospheric illumination.
Versatile Light Colors for Every Need: The POLAR light color at 7500K produces a natural, cool white-blue light - ideal for Malawis and Tanganjika Cichlids. The MARINE light color at 13000 Kelvin delivers an icy light with a high blue component. For specialized freshwater aquariums, MARINE is especially recommended for Tanganjika/Frontosas to create depth or cave effects. Or as an alternative moonlight shade to ROYAL-BLUE.
Customized Lighting Design: Combine multiple LED bars with the same or different light colors as per your requirement. The ideal selection and combination depend on various factors such as size, layout, planting, and occupants of your habitat. For more tips and recommended combinations, refer to our FAQ. Additionally, our light comparison tool helps visually compare the different light shades.
Features:
- Powerful and Brilliant: High-Power LEDs emit up to 33% more brightness than standard ones, creating a natural shimmer effect on the aquarium floor.
- Flexible Dimming: Manual or automatic brightness control for captivating day simulations.
- Sleek and Versatile: Compact profile of 32x18mm; available in 6 lengths ranging from 47-135 cm and 11 color variations.
- Convincing Quality: Solid aluminum single-piece passive heat sink for optimal heat dissipation and durability.
HEATING WITH LIGHT – Each PRO² LED strip can optionally be used with the innovative heat recovery system, although this is not mandatory. The temperature-optimized aluminum profile also ensures effective passive cooling without this technology. However, with active water cooling, not only is optimal cooling of the LEDs achieved, but the waste heat is also efficiently used to additionally heat the aquarium through heat recovery. This dual function is unique in the industry. For more details and a practical calculator for energy saving, please visit our website.
Tip: Using a dimmer allows gentle regulation of brightness without visible loss in luminosity. This reduces energy consumption and increases the lifespan – effects that can also be achieved through automatic light control or day simulation.

Caution! This product is a waterproof LED bar (IP67), which can also be used inside the aquarium cover to a freshwater tank. The permanent presence of moisture, the build up of dirt or lime deposits can adversely affect the light quality, output and service life of the LED bars. Therefore we recommend that our CleanCovers are used within the aquarium cover. LED bars cool passively by using the surrounding air. Therefore, there must be an adequate circulation of air. As a rule, the openings for cables and hoses in the cover are adequate for this purpose. Further information. Cautionary advice if the product is used in a seawater environment, see FAQ!
When using watter cooling with sea water or deviant fresh water (eg very low PH), we recommend using the TITAN upgrade.
