Identification & Application

Topaz T77052 LSA4P-50PCS-BL 30W/40W/50W 4ft LED Architectural Linear Downlight or Up/Downlight 3500K/4000K/5000K 120-277V

The Topaz T77052 (LSA4P-50PCS-BL) is a premium 4-foot architectural linear LED fixture with selectable wattage, selectable color temperature, and adjustable direct/indirect light distribution. This black suspended linear fixture allows installers to configure the illumination for the needs of the space instead of being limited to one fixed lighting pattern.

The fixture can be set for 100% direct downlight, 90% downlight with 10% uplight, or 70% downlight with 30% uplight. The 100% direct setting concentrates all illumination below the fixture for stronger task lighting. The 90/10 setting adds a subtle amount of ceiling illumination while maintaining primarily downward light. The 70/30 setting provides more uplight to brighten the ceiling and create a softer, more open architectural lighting effect.

Operating from 120-277VAC, the fixture offers selectable power settings of 30W, 40W, or 50W and selectable color temperatures of 3500K, 4000K, or 5000K. It delivers up to 6,100 lumens, supports smooth 0-10V dimming down to 10%, and provides a CRI of 80 with a rated life of 54,000 hours. The slim aluminum housing includes suspension aircraft cables and can be used individually or as part of a continuous architectural lighting layout.

The LSA4P-50PCS-BL is ideal for offices, conference rooms, schools, libraries, hospitality spaces, restaurants, retail interiors, and other commercial environments where flexible downlight and uplight distribution is desired.
