We might as well say it: LED products drove a major portion of the lighting systems innovation in 2004. Some of the most interesting included:

Element Labs' VersaTile makes tiles glow and change color, allowing large dynamic wall panels.

• Designer's Edge wall-mounted nightlights, a low-energy security lighting solution.

• TIR's Destiny series of exterior color-changing and accenting architectural lighting systems.

• GELcore's low-energy, effective street identification lighting system and its border light system for exterior and interior applications.

• Color Kinetics' iColor FX tile system, capable of making interesting and dynamic color patterns in tile shapes, and iColor Flex SL, an LED strand light.

Line by io Lighting, a linear product that produces an unbelievably tight beam.

• LED step lights from Semper Fi, Lucifer and B-K.

• Moon Cell's Econo-Lum 55W roadway light. A product desperately in need of industrial design, it is the first of many LED roadway lights we will see in the next years.

• Dialight's recessed 6W LED spot for replacement of low-wattage incandescent lamps, and an interior/exterior LED strip light.

Traxon's Mood Light Objects, a system of illuminated glass art and useful objects that change color, and Mood Light Reflector, a glass-faced tile system for color-changing.

• Orgatech's Rusty LED, an outdoor path or step light for maintenance-free, and linear wet-location color-changing wash lights.

• Altman's 36W LED theatrical floodlights.

• Tokistar's Trillium LED strip light modules with color changing.

Bruck's Ledra monopoints – beautifully designed using LED sources.

• K-tronic's LED emergency lighting system for residential use.

• From OutdoorlightSCAPES, LED underwater lights.

• Metamorphosis high-density IP65 LED wash lights from Space Cannon.

• Light Projects London's underwater lights.

• Lighting and Electronic Design's Show Glass features LEDs that float in a glass panel to make shapes or words.

This is just a sampling. What is impressive about the market is the wide range of products and the profound creativity of the product developers. However, designers should proceed carefully. Not all LED systems are created equal, and LED technology still suffers from low-efficacy, lumen depreciation, heat dissipation concerns, and limited power. james benya
