Requires a compatible 4-pin ballast (electronic or magnetic). Not compatible with 2-pin GX23 or GX23-2 sockets — verify your fixture's base type before installing.
• 3500K NEUTRAL WHITE — COMFORTABLE, NATURAL-LOOKING LIGHT — Produces neutral white light at 3500K (also marked as "835" on compatible bulbs), delivering a balanced tone that reduces eye fatigue and works well in offices, classrooms, retail displays, and residential spaces where warm-but-clear light is preferred. 82 CRI renders colors accurately for tasks requiring good color visibility.
