Description

Versatile 2x4 Backlit LED Lay-In Panel | CCT Selectable Lighting For Offices, Retail, And Classrooms With 0-10V Dimming

Designed for fast upgrades in commercial ceilings, this 2x4 backlit lay-in panel offers selectable color temperatures and adjustable lumen output so facilities can standardize fixtures while tailoring light to each space. The thin-profile panel reduces installation time and maintenance compared with legacy fluorescent troffers.

KEY FEATURES:

  • CCT Selectable: Choose from five color temperatures (3000K, 3500K, 4000K, 5000K, 6500K) to match application needs without changing fixtures.
  • Field-Adjustable Wattage & Lumen Output: Select 32W/40W/50W settings to balance brightness and energy use (4000/5000/6250 lumens respectively).
  • 0-10V Dimmable: Integrates with standard low-voltage controls for smooth dimming (10-100%).
  • Thin, Backlit Design: Diffuse PMMA lens delivers even illumination and low glare for comfortable workspaces.
  • Wide Voltage Range: 120-277V operation simplifies installation across commercial sites.

APPLICATIONS:

  • Ideal for office ceilings and open-plan workspaces where uniform, low-glare lighting is required.
  • Suitable for retail environments and showrooms that need adjustable color temperature for merchandising.
  • Great for classrooms, libraries, and healthcare support spaces seeking energy-efficient, tunable lighting.
  • Usage Tip: Use 3000K-4000K for general task lighting and 5000K-6500K for areas requiring high visual acuity or daylight appearance.
