Product Overview

The Universal Lighting Technologies 19937 Accustart B224PUNVC is a versatile programmed rapid start ballast supporting a wide range of T5HO and compact fluorescent PL-L and Dulux L/F lamp types across multiple wattages and base configurations — from 24W to 39W T5HO linear lamps and 24W/36W 2G11 and 2G10 plug-in CFL lamps. This broad lamp compatibility makes it a useful consolidation SKU for commercial facilities maintaining multiple lamp types.

Programmed rapid start preheats lamp cathodes before arc ignition, extending lamp life compared to instant start — particularly valuable in high-switching environments. End-of-life shutdown circuitry detects lamp failure and removes power to prevent lamp cycling and ballast overheating. Auto-reset after lamp replacement restores operation without requiring power cycling. Series lamp circuit operation means both lamps in a 2-lamp configuration operate on the same circuit branch.

Compatible Lamps

(1–2) F24T5HO — T5HO linear fluorescent
(1) F39T5HO — T5HO linear fluorescent
(1–2) FT24W/2G11 — Philips PL-L 24W/4P, Sylvania FT24DL/4P, Osram Dulux L 24W
(1–2) CFM24W/2G10 — Osram Dulux F 24W
(1) FT36W/2G11 — Philips PL-L 36W/4P, Sylvania FT36DL/4P, Osram Dulux L 36W
(1) CFM36W/2G10 — Osram Dulux F 36W

Compatible Applications

Commercial T5HO fluorescent fixtures — Offices, retail, and institutional fixtures using 24W or 39W T5HO lamps.
PL-L and Dulux L/F compact fluorescent fixtures — Commercial and architectural downlights, indirect luminaires, and cove lighting using 2G11 and 2G10 base plug-in CFL lamps.
Occupancy sensor and high-switching applications — Programmed start protects lamp cathodes in frequent on/off cycling environments.
Outdoor and low-temperature applications — UL Type 1 Outdoor for covered exterior and unheated space installations.

Before Ordering — Verify

Lamp Type: Confirm your lamp is on the compatible lamp list above — note that F39T5HO and 36W PL-L/Dulux lamps are supported for 1 lamp only.
Lamp Count: Confirm fixture requires 1 or 2 lamps. Higher-wattage lamps (F39T5HO, FT36W, CFM36W) are 1-lamp only.
Input Voltage: Confirm circuit is within 120–277V ±10%.
Lamp Circuit: This ballast uses series lamp operation — note the circuit behavior differs from parallel operation.
Physical Fit: Confirm 14.5" x 1.18" x 1.00" fits within your fixture's ballast cavity.
