We saw more LED lighting introductions at this year's Lightfair International than in any previous year.Here's a sampling of some new developments and products in LED lighting.Outdoor luminaires Schreder Lighting introduces outdoor and street-light luminaires We witnessed an abundance of outdoor LED street-light and area fixtures at Lightfair International 2012.For example,Schreder Lighting introduced the Piano family of street lights(shown)and also Focal fixtures for outdoor public spaces including athletic fields and landscape lighting applications.The stylish family of Piano luminaires(shown),designed by Michel Tortel,features optimized cooling of the LEDs and electronic driver.Thermix thermal management system is designed to maintain 70%of initial luminous flux(L70)for 100,000 hours according to Brian Keilt,eastern sales manager for Schreder.The optical system is sealed with an IP66-rated compartment.Schreder's new Focal fixture is constructed of die-cast aluminum,available with a variety of reflector and lens options and IP66 rated.Lamp position and beam angle can be adjusted on-site.LED lighting fixtures WAC Lighting shows indoor and outdoor fixtures WAC Lighting dressed up its stand at Lightfair with chrome and crystal LED luminaires that are less than 2x4-in in size(shown).The company also introduced its line of International Luminaires at Lightfair,which includes outdoor and indoor fixtures.In indoor luminaires,the Paloma Wall Wash Series,used on WAC`s track systems,features varied optical control to illuminate art or signage in commercial and hospitality environments.The series accommodates LED or T5 fluorescent sources.WAC Lighting's new architectural-grade outdoor fixture,the surface-mounted Panther luminaire,uses LED or metal-halide sources.A commercial grade outdoor wall sconce,made of cast-die aluminum features a 35°cut-off angle to reduce glare and shadows.Finally,Slana outdoor luminaires can be surface or pendant mounted.The 6-in recessed down-light shows no visible hardware,is constructed of die-cast aluminum and is IP20 and IP-65-rated.Retrofit lamps Next Lighting introduces LED replacement for T12s Introduction of Next Lighting Corporation's NEXTLamp LED lamp at Lightfair was timed to coincide with the US phase-out of T12 fluorescent lamps beginning July 14,2012.According to Next Lighting,there are over 500 million T12 fluorescent lamps installed in the US.Randall Sosnick,CEO of Next Lighting explained that each NextLamp uses natural convection through a chimney-like design that flows next to the linear lamp to best dissipate heat from the LEDs(shown).Product testing has measured the lamp's case temperature at 51°C,allowing the company to specify a 50,000-hr life.Lumen output per lamp is 3500 lm.A proprietary optical system reduces glare,a common issue with linear LED lighting.The lamp's driver is commonly located underneath the ballast or can be positioned in the ceiling with the company's forthcoming pendant configuration.The NextLamp will be available in 3Q 2012.LEDnovation introduces 35W and 50W equivalent LED MR16 At Lightfair,LEDnovation showed its latest 50W-equivalent and 35W-equivalent LED MR16 lamps.The EnhanceLight 50W equivalent is offered in two beam angles,11 and 23°,delivering center-beam intensities of 7360 and 2300 cd at CRI of 80 and 82,respectively.Both lamps require 8W to operate.In the 35W-equivalent MR16 lamp,LEDnovation has a 11°spot in production and it introduced the 24°narrow-flood design at Lightfair.In the 24°beam angle version,the lamp delivers 1301 cd and CRI of 82 at 4.7W operation.Designed for use in IP66 rated outdoor fixtures,the EnhanceLite MR16-35L lamp is designed for harsh environments.The lamp fits the ANSI standard C78.24-2001 specification,is dimmable to 5%on a range of dimmers and is rated for 35,000 hr.Lunera Lighting introduces 2x2-ft LED troffer At Lightfair,Lunera Lighting showed its recently introduced 2x2-ft troffer,with an efficacy of 110 lm/W and lumen output up to 8000 lm.Other companies that have recently introduced 2x2-ft LED troffers include Cree and MGE Lighting.The third-generation troffer is based on the Lunera 2x2-ft Series 22-G3 form factor,uses Nichia LEDs,and is available in various lumen packages.Lunera also showed its intelligent hybrid daylight system of sensors and controllers at Lightfair,which are capable of automatic LED lighting adjustments for retail spaces,schools and warehouses.Also at Lightfair,four Lunera partners,Lutron,Enlighted,Adura Technologies and White Light,used Lunera third-generation luminaires to demonstrate their products.
