Finelite's Linear Trio 3 (LT-3) is a streamlined 3-inch linear luminaire built on a 6063-T6 extruded aluminum body with a 3-sided radius lens, whose mid-power LEDs deliver a semi-direct distribution. Five lumen packages are published for the 4 ft, 3500K, 80 CRI photometry: Standard 500 lm/ft, Boosted 750 lm/ft, High 1,000 lm/ft, Very High 1,175 lm/ft, and Extremely High 1,400 lm/ft — up to 5,600 lumens per 4 ft section at up to 138 lm/W. Static-white LEDs are offered at 2700K, 3000K, 3500K, 4000K, and 5000K in 80 or 90 CRI, alongside 80/90 CRI tunable-white options. Runs build from 2 ft minimum sections (increments to 1 ft, ±1/32") up to a 12 ft maximum section, mounted as pendant, surface, or wall. Standard 0–10V dimming runs 100%–10%, with 1% and EldoLED 0.1% options plus DALI, DMX, and Lutron EcoSystem drivers. Signal White is the standard finish, with Finelite Black, Satin Aluminum, and 179 RAL colors available. Linear Trio 3 is rated for damp locations, is ETL-listed to UL 1598 / CSA C22.2 No. 250.0, carries a 10-year performance-based warranty, publishes L90 at 55,000 hours, and is enrolled in the ILFI Declare program with Red List Approved and Red List Declared options.
