2” aperture direct/indirect acoustic panel luminaire

CutsheetExplore HL2



The HL2 direct/indirect luminaire is designed to enhance interior spaces with subtle to bold colors, while damping sound reflections.

The 2” wide aperture fixture is clad with ½” thick felt acoustic panels in 8”, 12” or 16” heights and twenty standard colors. Machined aluminum end caps are available in several architectural finishes, as well as optional RAL finishes to coordinate with panel colors. Add additional sound absorption in an architectural space with complimenting HB2 non-illuminated acoustic baffles.



Fixture constructed of extruded aluminum, heavy gauge sheet formed steel and aluminum, extruded acrylic lenses and PET acoustic felt panels.

Model variations offered for cable suspended and wall mount applications as 2’-8’ nominal single fixtures and continuous runs up to 50’.

The 1/2” thick, 100% PET (>75% recycled), fire rated (ASTM E84 Class B) 0.98 NRC acoustic felt panels feature a bottom beveled edge, extended ends and are available in twenty standard colors.

Unlit areas and standard machined aluminum end caps are available in standard powder coat finishes as shown below and optional RAL finishes coordinated to the panel colors.

Indirect Lambertian and batwing optic options are available.

Basic continuous run fixtures provided with 18 ga. wiring harness for 6 Amp maximum load (consult factory for runs requiring multiple circuits, sensor integration, etc.).

Standard integral 120-277V driver offered with 0-10V dimming or non-dim (other dimming driver options available).

Integral 120-277V emergency battery backup available for non-dim or 0-10V fixtures and operate the direct source in 4’ sections within the run (consult factory for details and for compatibility with other drivers).

Standard light outputs range from 445 – 860 lumens per foot for the direct source and 455 – 1340 lumens per foot for the indirect source.

LEDs available in 2700K, 3000K, 3500K and 4000K, within a 3 step MacAdam ellipse, all with 90+ CRI typical.

Life: 50,000 hours L70.

Limited five year warranty.

UL and C-UL listed for dry and damp locations.

Made in U.S.A.
