LTwo® comes in 4 basic looks and two colors. The looks are determined by the functional design of the optics/louver. Round louver: 10°, 13°, 25°, 40°, Batwing Narrow (BWN), and oval optic (13° x 40°). Rectangular louver: 60° and Batwing Wide (BWW). Asymmetric louver: Wall Wash (WW). Round LTwo®: clear, diffuse, or opal cover.

The color of the housing and the anti-glare are available in white and black. A white LTwo® comes with a white anti-glare and a black LTwo® with a black anti-glare. Other combinations and colors might be available on request depending on the volume.

LTwo® is available in Constant Current (CC) or Constant Voltage (CV). Constant Voltage provides more flexibility if more lamps are used on a single driver. It’s less efficient than CC, and the drivers are more expensive. Constant Current is more efficient than CV. The drivers are less expensive and available in more sizes and with more lighting control (smart) options. A maximum of two lamps can be connected to one driver in CC mode. CC requires more wiring during installation.

In Constant Voltage (CV), two power levels are available: either 12 W/m or 20 W/m. The product can be dimmed with PWM. In Constant Current (CC), the product has a rated power of 25 W/m @ 600 mA drive current. It can be driven at higher currents for more lumen output, as long as proper heat management is ensured.

LTwo® comes in lengths of 142 mm (1/2 ft), 282 mm (1 ft), 562 mm (2 ft), 842 mm (3 ft), 1,120 mm (4 ft), and 1,400 mm (5 ft). Depending on operating current and nominal power, the output of the light source ranges from 1.8 W / 240 lumens to 35 W / 5,600 lumens. For details regarding the precise performance data, depending on the optic used, please refer to the specific datasheet.

The entire product range is offered with 12 different high-performance architectural lighting optics, meeting the highest standards in uniformity, color-over-angle, and glare control. The optics are available in 10° HB, 13° Spot, 25° Narrow Flood, 40° Flood, 60° Wide Flood, 90° Extra Wide Flood (coming soon), Batwing Narrow (BWN), Batwing Wide (BWW), Wall Wash (WW), a clear lens (max. efficiency), and a frosted and opal lens with Lambertian characteristics.
