Lighting system

The TL201LED low-power LED lighting system consumes less than 15% of the power of conventional-watt low-voltage xenon lamps and has a life of 50,000 hr, according to the company. Designed for use with the company's Trac12 miniature low-voltage trac system, the product operates using a 12V, 75W magnetic AC transformer that can power runs up to 36 ft with modules spaced 3 in. on center. The unit also features a 1-in. × 1-in. low-profile design and has a color rendering index of 80. In addition, it is available in either warm 3,000K or cooler 5,000K color temperatures and can be dimmed down to 0% with a selection of incandescent dimmers.

Spotlight bulb

This Par30-style LED bulb is comprised of five 3W high-power LEDs. A direct replacement to 50W to 75W PAR30 incandescent bulbs, the product combines LED technologies, a standard 25-mm Edison screw-in base, and light-optimizing designs to produce 480 lumens to 544 lumens of light, depending on the bulb model. Available in a 40° light-emitting viewing angle, the product runs on 80VAC to 260VAC current. Additional voltages, such as 12VAC or DC, are available for qualifying customers. According to the company, the bulb has a maximum power draw of 15.8W and is available in color temperatures of 3,000K and 5,000K.

Luminaires

The EssentialWhite Series now includes two LED luminaires. The eW Downlight SM Powercore features a low-profile housing. Measuring 7½ in. × 7½ in. × 2 in., the downlight is available in color temperatures of 2,700K and 4,000K. The eW Profile Powercore is a low-profile, linear fixture. Powered by line voltage, the company says the fixture consumes 6W of energy per foot and can support a run of up to 50 ft on a single circuit. Measuring ⅞-in. thick × 1½-in. wide, it is available in 11-in., 21-in., and 41-in. lengths and in color temperatures of 2,700K and 4,000K. Both LED luminaires directly accept line voltage and are compatible with commercially available ELV-type line voltage dimmers.
