The Heart of the Aqua Illumination System – Powerful LEDs and Lenses

AI incorporates into their luminaires some of the most powerful LEDs on the market– SeoulSemiconductor’s Z-Power ‘P4′ white LEDs (3.8 watts each) and blue LEDs (2.5 watts each). These, in conjunction with Khatod lenses manufactured especially for use with Seoul Semiconductor’s LEDs, result in focusing light into strong ‘beams’ which put light where you want it – into the aquarium and not on the walls and floor.

The white LEDs are ~6,500K, and the ‘blue’ LEDs peak at a wavelength of 460 nm.

Methods

Photosynthetically active radiation (PAR) was measured with an Apogee Instruments quantum meter with cosine-corrected submersible sensor. This instrument is within its recommended 2-year calibration period.

A hand-held Project Star spectrometer demonstrated a visual display of light energy between 400 and 700nm, and was recorded by an Olympus C-5050 digital camera in ‘macro’ mode.

Spectral quality was analyzed with an Ocean Optics USB-2000 spectrometer and cosine-corrected CC-3 collection lens. Raw data from the spec was interpolated to 1nm increments. This information was further analyzed for color percentage in a proprietary Excel program.

Temperatures were measured with a ‘laboratory grade’ mercury thermometer and a laser-sighted infrared temperature ‘gun’.

Comparison of the LED and Metal Halide PAR were made under similar conditions. Distance from the lamp(s) was 5 inches. LEDs were, of course, housed in AI’s luminaire.

The metal halide (an XM 250-watt 20,000K; burn time ~100 hours) used a polished aluminum parabolic reflector and was driven by a Coralife ballast. There was no ‘shield’ between the lamp and sensor. PAR measurements were taken every 1″ across a black grid.

Spectral Analyses

See the ‘Methods’ section for a description of spectral analyses protocols.

White LEDs

The AI luminaire houses 16 white LEDs. Generally, white light is produced by a LED generating blue light in combination with fluorescent phosphors. These phosphors absorb some of the blue radiation and fluoresce it as broad spectrum light, resulting in a ‘white’ light.

Hidden Champions of the Twenty-First Century: The Success Strategies of Unknown World Market Leaders $34.95 What do Tetra aquarium supplies, Elector-Nite sensors, and Nissha touch panels have in common? They are typical “hidden champions,” medium-sized, unknown companies (with annual revenues under $4 billion) that have quietly, under the radar, become world market leaders in their respective industries. Hermann Simon has been studying these hidden champions for over 20 years, and in this sequel to his worldwide bestseller, Hidden Champions, he explores the dramatic impact of globalization on these companies and their outstanding international success. Going deep inside more than a thousand hidden champions around the world, Simon reveals the common patterns, behaviors, and approaches that make these companies successful, and, in many cases, able to sustain world market leadership for generations, despite intense competition, financial pressures, and constantly evolving market dynamics. In the tradition of In Search of Excellence, Built to Last, and Good to Great, Simon identifies the factors in business operations, customer service and marketing, innovation, human resources management, organizational design, leadership, and strategy that separate these outstanding performers from the rest of the pack – and from the large corporations of the day. In the process, he provides a glimpse behind the curtains of many secretive companies who buck today’s management fads, and succeed instead through such common-sense strategies as focusing on core capabilities, delivering real value to the customer, establishing long-term relationships, innovating continuously, rewarding employees for performance, decentralized operations, and developing an unparalleled global presence. Hidden champions teach us that good management means doing many small things better than the competition—quietly, with determination, commitment, and never-ending stamina. And in turbulent economic times, the hidden champions represent an antidote to the short-sighted and excessive practices

Jaw morpho-functional diversity, trophic ecology, and historical biogeography of the neotropical suckermouth armored catfishes (Siluriformes, Loricariidae). $49.99 Tropical South America is renowned for its unparalleled biodiversity. Among vertebrates, fish diversity exceeds that of any other group. Estimates of total Neotropical fish richness range between 5000 and 8000 species, of which approximately 3600 (45–72%) are currently described; and of described species, nearly 20% (>700 spp.) are catfishes in the Neotropical-endemic family Loricariidae. Loricariid catfishes, popularly known as plecos in the aquarium trade, are distinguished by their armor plating, ventral oral disk, and highly derived jaw structure and function. Loricariids have likely existed in South American rivers in close to their modern form since at least the Late Cretaceous, and they are part of a superfamilial lineage (Loricarioidea) that is sister to all other catfishes, and has likely inhabited South American rivers since well into the Early Cretaceous. Today, loricariids have radiated to consume a variety of basal food resources including algae, detritus, seeds, sponges, insects, and even wood, the surface layers of which are gouged into by specialized taxa having hypertrophied jaw muscles and teeth shaped like adzes.;In this dissertation, I attempt to fill major gaps in the knowledge of loricariid taxonomy, jaw morphological and functional diversity, trophic ecological structure, and historical biogeography. My taxonomic research has resulted in the discovery and/or description of dozens of new loricariid species and at least three new genera. Published results of this work are summarized in Appendix I. In chapter two of this dissertation, I describe jaw morpho-functional diversity across a diverse assemblage of 25 species, 12 genera, five tribes, and two subfamilies of loricariids from the upper Amazon Basin in Northern Peru. In chapter three, I describe gross aspects of loricariid assemblage trophic structure as revealed by carbon and nitrogen isotope data from 19 loricariid assemblages ranging in species richness from two to 16 species, and
