Sicce Pro LED System 60w The most technically advanced and energy efficient aquarium lighting system available today. Cutting edge Italian design and rigorous testing combine to produce a sealed, solid-state system that creates a dome of high PAR value illumination over the entire aquarium area! Unique, proprietary white LEDs are combined in a carefully determined ratio with blue LEDs to achieve an overall temperature of 14,000K. When installed according to our recommendations, every SICCE LED Lighting System provides illumination of the correct intensity, spectrum and dispersion for the photosynthetic zooxanthellae of corals, giant clams and other reef organisms in all parts of the aquarium. Settings enable you to switch between sinrise, sunset, full daylight and night mode. Competing units simply cannot match these specifications. In addition to providing optimal reef aquarium illumination, SICCE LED Lighting Systems offer many features designed for the convenience of the aquarist. Sealed, double Oring construction protects all electrical components from water. The integrated aluminum heat radiator eliminates the need for a cooling fan, and with it a lot of other hassles. There are no moving parts to break. No fan means no noise; the unit is completely silent. With no forced air movement, there are no vents or gratings to trap dirt and require cleaning. The Sicce LED Lighting also features a built in timer with sunrise and sunset program options and complete with a 5 year warranty for peace of mind. Specifications: Sicce Pro LED System 60w Dimensions: 14.5 x 14.5 x 1.5\" Weight: 9.7lb Tank size: Up to 12-24\" long Number of LED\'s: 196x white 14 x Actinic blue LEDs Total Power Consumption: 60W What to see a comparison to the Radion? Look here Further Information: Instead of using the high-output diodes found in most LED units, these new fixtures imitate natural sunlight by incorporating a profusion of low power white LEDs and high output blue LEDs for great penetration and uniformity of light. The lamps are mounted on printed circuit boards and are supplied with constant current power packs that operate well below the so-called nominal current. This design guarantees the longest possible lamp life and maximum energy efficiency. The LED lamp field is sandwiched between a silver anodized aluminum heat radiator and a thick layer of acrylic. This creates a sleek, modern appearance, but, more importantly, this design avoids using a noisy fan, making our fixtures completely silent. SICCE LED watertight fixtures are manufactured to exacting standards with zero chance of lamp placement errors and to optimize lowest possible operating temperatures and heat dissipation without the noise common to ventilating fans. The double o-ring sealed LED lamps are completely watertight preventing oxidation of electronic cards by contact with water and humidity. After extensive collaborative testing with experts in the industry, the perfect ratio of white to blue lamps for maximum coral growth was determined. Whereas most aquarium LED lights use either high output or low output LEDs, SICCE LED light uses multiple rows of white diodes supplemented by higher-output blue diodes in a ratio of 14 white LEDs to one blue LED. SICCE blue LEDs have an emission peak at 446nm, producing the blue color that many reef aquarists find most attractive over corals, and complimentary to the cool white look of most white LEDs. Other manufacturers incorporate red LEDs into their fixtures and claim to achieve higher output and greater energy efficiency. In reality, higher energy efficiency can only be achieved by pushing the wattage to 1 watt per diode. Incorporating chips that operate at greater than 1 watt actually decreases performance. 1 watt = 100 lumens, while 2 watts = 170 lumen, not 200 lumens, as would be expected. Red LEDs simply consume more power. SICCE LEDs have an average color temperature of 14,000? Kelvin, because we use a higher number of white and fewer blue LEDs. We have achieved the perfect balance between proper illumination for reef organisms and energy efficiency by using this combination. SICCE LED lighting systems have separate controls permitting the blue and white LEDs to be turned on and off independently. A factory-set sunrise/sunset feature comes standard with all units, but may be disabled without compromising either illumination or efficiency. With our compact, energy efficient, sleek design and effective illumination, SICCE sets the new standard in LED lighting. SICCE LED Lighting, a product of over 30 years of technical and design experience, provides these important features: • High-efficiency LED lamps for maximum lumen output and minimal power consumption • Optimized for even illumination over the entire tank • Safe, efficient and SILENT heat dissipation without noisy fans • Light spectrum does not shift over time • Modular design is ready to upgrade when you are • Built-in timer with sunrise/sunset program option • 5-year warranty These units are held by the UK Sicce warehouse so please expect 2-3 days for delivery when ordering.
