  • Quality & reliability
    The new, slimmer design saves energy, with passive cooling and longer lifespan.

Designed to achieve a beautiful, natural coral reef

The next generation of CoralCare’s innovative LED fixture is here. The CoralCare Gen2 offers a new, slimmer design, with passive cooling and wireless control. What’s more, we’ve further refined the light spectrum and distribution to create a more natural reef appearance, natural light patterns, and promote coral growth.

Excellent coral growth & natural reef appearance

Let life flourish with a wide spectral range. Proper lighting is one of the key aspects when maintaining a marine aquarium with corals and reef fish. The corals need the correct light intensity and spectral content to grow efficiently, but reefers also demand seamless color rendering so they can enjoy the brilliantly vivid colors of the corals. The Philips CoralCare spectral distribution is designed to achieve an ideal balance of those two criteria.

With the CoralCare Gen2, we’ve further optimized the light formula in order to enhance the natural color rendering in daylight settings and maximize the fluorescence of the corals in evening settings. The new Gen2 design features 68 state-of-the-art LEDs, smartly grouped over two distinct user-controlled channels. This offers you control over a wide range of color points (from natural white to saturated blue) without ever worrying about harming your corals with the wrong spectral content.

Natural light patterns

Just as with CoralCare Gen 1, the light is homogeneously mixed and distributed thanks to the optical light guide and diffused glass plate. We've further refined this with CoralCare Gen 2 by grouping the LEDs in triangular clusters and adding four carefully placed clear areas in the glass plate.

The cluster placement is deliberately chosen to create subtle but natural light patterns in the water. The clear areas in the glass plate add extra dynamic light effects when warm natural color points are selected. This mimics the patterns perceived on the ocean floor at noon when the sun is at its highest point. During the evening, when blueish color points are being selected, this dynamic effect fades just like it does in nature.

This architecture results in an ideal balance between efficiency, uniform light distribution in the aquarium, color homogeneity, and the right level of light dynamics.

Easy to control & install

Your CoralCare Gen2 LED fixture can be controlled wirelessly using your mobile device or with your PC. In addition, it includes a 0-10V port so you can connect the light to third-party aquarium controllers like the Neptune Systems Apex, and GHL ProfiLux. What's more, your new wireless controller is also compatible with CoralCare Gen1 fixtures.

Choose from user-friendly preprogrammed lighting schedules or easily create a custom 24-hour lighting schedule to suit your coral needs. You can even share your lighting schedules with other reefers!

Direct control is also available for maintenance or checking on your reef inhabitants. There's an acclimatization phase for introducing new corals or installing new CoralCare lamps, which allows you to gradually increase the intensity of the light to match the needs of your corals. The single box system (with integrated drivers) also includes a hanging kit for quick and easy installation with adjustable height and positioning.

Quality & reliability

CoralCare Gen2 is carefully tailored to suit the demanding conditions of your aquarium.

The new, slimmer design is still passively cooled and uses the most efficient LEDs on the market—all without any loss of light quality.

Quality & Reliability

The CoralCare LED fixture Gen2 is based on an existing Philips fixture used in a large variety of general lighting applications. This fixture is being used in warehouses, public swimming pools and exposition halls and has proofed to be a very robust design. For use in marine aquaria, it has been redesigned to such an extent that it meets all marine aquarium requirements and thus withstands the conditions of this demanding environment.

The CoralCare LED fixture is made of highly durable professional-grade materials which we have extensively validated. As the first CoralCare generation has proofed to be extremely suitable for marine aquarium applications, the choice to go for an equivalent design – made of the same materials - for the second generation was rapidly made.

The coating of the metal housing has been validated in a salt spray environment and approved for use above marine aquaria. With proper maintenance the risk of corrosion is nil.

By using approximately 7kg of metal, the luminaire has a large thermal cooling surface, allowing full passive cooling, which is beneficial for the lifetime and robustness of the luminaire. Active components (fans) are the most common cause of defects, are noisy and ultimately determine the lifetime of the product.

The CoralCare glass cover helps reduce maintenance as the salt water particles can easily be removed. A further advantage is that it does not need to be disassembled for cleaning.

In addition, the cover has an IP65 rating, which makes the fixture water-resistant. It can also be cleaned with a wet cloth. The same accounts for the CoralCare Controller. In other words, the complete CoralCare Gen2 system is very robust.

By having a light formula with a large amount of short wavelength light we could be faced with the risk of rapid material degradation. Validated lifetime tests, however, have shown that the materials used withstand our light recipe and meet the lifetime specification.

The CoralCare LEDs are placed on a so-called MetalCore PCB. Because of the high diversity of LEDs placed on this PCB, manufacturing and assembling such a large MC PCB is quite challenging and affects reliability and failure rate. PCB warpage, solder reliability and material degradation are such critical examples. For CoralCare, extensive testing such as thermal shock was carried out in order to guarantee lifetime reliability.

LEDs from our key supplier Lumileds are used in the CoralCare fixture. These are very durable, high-quality, long-lasting and highly efficient LEDs. Moreover, in order to ensure color and performance consistency, a special process is carried out just after LED manufacturing. See also CoralCare LED spread analysis in Wide Spectral Range.

From a thermal point of view the stress to the LEDs is limited.

Via model analysis and reliability tests we can predict that the CoralCare fixture meets L80B10 (ambient temperature of 35°C and lifetime of 25K hours), which is a standard norm in general lighting. This means that after the lifetime of 25K hours (about 7 years), at its specified ambient temperature point of 35°C, 90% of all fixtures still give an output of more than 80% of their original lumen output. By comparison, with traditional T5 lighting this point occurs after 6 to 9 months. No light source has to be replaced during the entire lifetime of the luminaire.

When changing the installation conditions (dimming, lower/higher ambient temperature), lifetime results are affected in a positive (dimming) or negative (higher ambient temperature) way.

In addition, as safety of our products is our highest priority, all required regulations for the marine aquarium application such as CE, IEC and UL have been checked by Philips and validated by external agencies. These quality marks show that the design of the CoralCare fixture and controller is safe and is 100% fit for the application.

Low energy consumption


Thanks to the use of highly efficient LEDs, the CoralCare fixture can save up to 30% or more energy compared with traditional T5 marine aquarium lighting, without any loss of light quality.

We have proved, together with an independent marine biologist, Tim Wijgerde, that with the CoralCare LED fixture coral growth and appearance meet and at some points exceed standard traditional lighting in the marine aquarium market.

With integrating sphere measurements CoralCare has a wall-plug efficiency of 29%. This means that 29% of the input power (about 170W) is being converted to optical power. As a reference, at its most efficient (= at initial lifetime cycle), T5 with the same color point only converts 24%.

The CoralCare optical system was designed in such a way that it has very limited efficacy losses thanks to the highly reflective materials and smart design
