View Specifications

TruLine 1A, a versatile 24VDC linear plaster-in LED system, creates a glare-free, smooth line of light indoor architectural lighting. The system recesses into 5/8" thick drywall without joist modification. May be secured to studs that are spaced 13"-24" apart, or between studs with mounting clips provided. TruLine 1A is sold in 1' increments up to 40' (2WDC, White LEDs only), 20' (5WDC, White, 2K4K or RGB LEDs) or 16' (6WDC, RGB+W) and field cuttable to any length. Several color temperature options are available, including 2200K-5700K (ELV/010), Warm Dim (ELV), Tunable White (ELV/010/DMX), RGB and RGB+W (DMX). High CRI commercial-grade White or Dynamic Color Changing LED Soft Strip projects a clean line of light. Coordinate installation with electrician and drywall contractors. Includes a 5 year pro-rated warranty
