Product Overview

The Philips Optanium IOPA2P32LW-N is a low ballast factor electronic instant start ballast designed for 2-lamp T8 systems where reduced light output and lower system wattage are required. A ballast factor of 0.77 means lamps operate at approximately 77% of rated light output — delivering meaningful energy savings in applications where full light output is not necessary, such as daylit spaces, perimeter zones, or energy code compliance strategies.

IntelliVolt technology automatically operates across 120–277V without voltage-specific configuration. Lamp striation reduction technology minimizes visible swirling in energy-saving T8 lamps. The low-profile housing (9.5" x 1.7" x 1.18") fits compact fixture designs.

Important: The 0.77 ballast factor reduces lamp light output to approximately 77% of rated lumens. If full lumen output is required, specify a normal (0.88) or high output (1.0+) ballast factor model instead.

Compatible Applications

Energy code compliance and lighting power density reduction — Low BF (0.77) reduces system wattage and lumen output for energy code compliance in over-lit spaces.
Daylit zones and perimeter lighting — Reduced output appropriate where daylight supplements artificial lighting.
Commercial T8 fluorescent fixtures — Troffers, strip fixtures, and wrap-around luminaires using 2-lamp T8 configurations.

Before Ordering — Verify

Ballast Factor: This ballast has a 0.77 low output ballast factor — lamps will operate at approximately 77% of rated lumens. Confirm reduced output is appropriate for your application before ordering.
Lamp Type: Confirm your lamps are on the compatible lamp list above.
Lamp Count: This is a 2-lamp ballast. Confirm your fixture requires exactly 2 lamps.
Input Voltage: Confirm your circuit voltage is within 120–277V.
Start Method: Instant start does not support dimming and may reduce lamp life in high-switching applications.
Physical Fit: Confirm 9.5" x 1.7" x 1.18" dimensions fit within your fixture's ballast cavity.
