Description

The MLF04 is a 4ft LED linear strip light built for commercial and industrial ceilings, with both color temperature and output wattage adjustable right in the field from a single SKU. A cold-rolled steel housing doubles as the LED heatsink, and a PC lens shapes the output for uniform, comfortable light at up to 157 lm/W. One fixture covers a full range of jobsite needs: pick any of 5 CCTs (2700K-5000K) and any of 4 wattage/output levels (40W down to 22W) on site, with no need to stock multiple SKUs.

• 4ft length (1219mm/47.9in); can be joined end-to-end in a continuous row with the optional Joiner Bracket Kit
• Field-selectable CCT: 2700K, 3000K, 3500K, 4000K, or 5000K
• Field-selectable wattage: Lv1 40W / Lv2 34W / Lv3 28W / Lv4 22W, from 3,080 up to 5,890 lumens depending on the CCT and level selected
• Efficacy up to 157 lm/W
• <5 SDCM color consistency; 80 CRI
• PC lens designed for uniform, comfortable light distribution
• Cold-rolled steel housing, heatsink, and J-box cover; housing acts as the heatsink for LED heat dissipation

• 0-10V dimming driver, 10%-100% dimming range
• PF > 0.9, THD < 20%
• Surface-mounted by default; can also be pendant-mounted via chain, aircraft cable (steel wire), or T-grid bracket (mounting kits sold separately); optional wire guard available
• Optional plug-and-play PIR sensor (with or without Bluetooth) or microwave sensor via the built-in sensor receptacle — no on-site modification needed

• UL/cUL Listed for damp locations
• DLC Premium qualified; patented design
• 5-year limited warranty

Applications

General ceiling lighting for commercial spaces, warehouses, parking structures, corridors, and retail spaces where field-adjustable color temperature and output on a single stocked SKU are valuable.
