Housing and Design
The VERS family boasts a sleek, unified housing profile available in lengths up to 8 feet. Constructed from heavy-duty anodized aluminum, it offers durability and a premium aesthetic. Standard finishes include satin black, bronze, and white powder coat, with custom color options also available. Machined aluminum endcaps add a touch of sophistication and secure the fixture with a set screw.
The underside features strategically placed grooves designed for seamless mounting. These grooves accommodate various mounting options which slide or click into place, remaining hidden for a clean finish.
Light Engines and Performance
QTL's VERS line is compatible with a wide array of high-quality LEDs, including static white, high-efficacy options. Color correlated temperature (CCT) ranges from 2000K to 4000K, all within a single bin for consistent color rendering. CRI ratings reach 98, providing near-perfect color accuracy.
Warm dim strips link light intensity and CCT, creating a warmer tone as intensity decreases. Tunable white strips offer independent control over CCT and intensity, allowing users to adjust the mood without altering brightness. Static color LEDs (red, green, blue, amber) and color-changing RGB options (RGB, RGBW) are also offered.
Mounting Options
VERS fixtures can be surface-mounted or suspended. Surface mounting options include concealed stainless steel clips, magnets, or T-bar clips. The stainless steel clips provide a completely hidden mounting solution. Magnets are suitable for ferrous surfaces, with a magnet mount accessory available for non-ferrous surfaces.
T-bar clips easily snap onto ceiling grids, offering compatibility with various grid systems. Suspension kits with round or square canopies (2” to 5”) in black or white provide hanging installation options.
Wiring and Connections
For surface-mounted VERS profiles, clean installations are achieved using wireway options. Single fixtures have power fed directly into the fixture, while pass-through connections enable power distribution for longer runs with multiple fixtures.
Suspended fixtures are limited to a single feed at the bottom. CON connectors are UL-rated and wet-listed, available in bare wire (CON6 with 6” wire, CON24 with 24” wire) and in black or white.
Lens Options and Applications
The VERS family offers a range of lens options to suit various applications. The VERS 1 Proud lens sits above the extrusion for maximum light engine options. VERS 2 Flush features a lens integrated within the extrusion for a seamless look. VERS 3 Clear maximizes lumen output with its high-quality lens.
VERS 4 Grazer utilizes dual optical lenses for a grazing effect (25° and 12° options). VERS 5 Optics offers enhanced beam control with 40° or 50° lenses. VERS 6 Encapsulated provides moisture, dust, and impact resistance (IK10 rating).
Additional Lens Options
VERS 7 Louver incorporates an internal louver to minimize glare, available in clear or diffused. VERS 8 Insert offers Batwing and glare control options for optimal spread and reduced glare. VERS 9 Asymmetric provides asymmetric light distribution (45° beam shifted 30°), ideal for artwork or signage.
VERS 10 Drop Lens delivers three-sided illumination for direct view or suspended applications. VERS 11 Nano Louvers features a co-extruded lens with an integrated 35° cutoff louver (crosswise or lengthwise options) to reduce glare.
