Osram QT-ECO 1X18-24/220-240 S

TCI BCC 116 (137945HTC) Multi-Lamp Electronic Ballast – Replaces Discontinued Osram QT-ECO 1X18-24/220-240 S | 220–240V | T5 / T8 / CFL | 4–28W

The Osram Quicktronic QT-ECO 1X18-24/220-240 S electronic ballast has been discontinued. The TCI BCC 116 (code 137945HTC) is the recommended direct replacement. It is a compact multi-lamp, multi-power electronic ballast operating on 220–240V (operating range 198–264V, 0–50/60 Hz), compatible with a broader range of fluorescent lamp types and wattages than the original Osram unit, including T5 (G5), T8 (G13), TC-S/E (2G7), TC-D/E (GX24q-1), and TC-DD (Gr10q) lamps from 4W to 28W. It is dimensionally compatible with mechanical ballast mounting positions, features push-wire connections, and provides preheat start for extended lamp life. Please verify lamp type, wattage, base, and supply voltage before ordering.

Product Overview

The TCI BCC 116 is a compact multi-lamp, multi-power electronic fluorescent ballast designed as a direct replacement for the now-discontinued Osram Quicktronic QT-ECO 1X18-24/220-240 S. The BCC 116 operates on 220–240V (operating range 198–264V) at 0–50/60 Hz, supporting both AC mains and DC emergency lighting applications.

The preheat starting method cathode-heats the lamp electrodes before ignition, which significantly extends lamp life compared to instant-start ballasts — particularly important in applications with frequent switching cycles. Built-in protections include automatic lamp disconnection (with restart via preheating), lamp failure detection, and end-of-life shutdown. Push-wire connections and M4 screw-slot mounting make the BCC 116 a drop-in replacement in fixtures originally designed for the Osram QT-ECO, as both units share compatible dimensions and mounting patterns.

A notable advantage over the original Osram unit is broader lamp compatibility: while the QT-ECO was limited to 18W and 24W lamps, the TCI BCC 116 supports T5, T8, TC-S/E, TC-D/E, and TC-DD lamp types across a 4W to 28W wattage range, providing flexibility for fixture conversions and multi-lamp-type inventories.

Compatible Applications

• Replacement for discontinued Osram QT-ECO 1X18-24/220-240 S in existing fixtures
• Commercial and institutional fluorescent fixtures with T5, T8, or CFL plug-in lamps on 220–240V mains
• DC emergency lighting systems (0 Hz operation supported)
• New fixture builds requiring a compact electronic ballast (Class I or Class II fixtures)
• OEM luminaire integration (version without housing available as BCC 116 OF)

Before Ordering – Verify

• This is a 220–240V ballast (operating range 198–264V). It is not compatible with 120V North American building power. Confirm the supply voltage at the installation before ordering. If the fixture is wired to standard US 120V, this ballast will not operate.
• Replaces Osram QT-ECO 1X18-24/220-240 S (Osram product code 4050300638560). If your records reference the Osram QT-ECO, the TCI BCC 116 (137945HTC) is the recommended replacement.
• Confirm the specific lamp type, wattage, and base match the BCC 116 compatibility matrix above before ordering; not all wattage/base combinations in the 4–28W range are supported.
• Ignition requires a minimum of 198V; if used on a battery-backed emergency circuit, confirm the battery voltage does not drop below 198V during emergency operation (the battery voltage may drop to 176V on some systems, but the ballast requires 198V minimum for ignition).
• EMC compliance at 0 Hz (DC) and 60 Hz operation is the responsibility of the luminaire manufacturer, not the ballast manufacturer.
• The BCC 116 dimensions (80 × 41 × 18mm) are compatible with mechanical ballast mounting positions; confirm physical clearance in the fixture before installation.

Safety and Installation Guidelines

• Disconnect power before installing, removing, or replacing the ballast
• Wiring must be performed by qualified personnel in accordance with local electrical codes
• Confirm the fixture is rated for Class I or Class II protection as appropriate for the installation
• Input and output terminal blocks are on opposite sides of the ballast; route wiring accordingly to maintain separation between supply and lamp leads
• Do not exceed the tc (maximum case temperature) of 75°C; ensure adequate ventilation within the fixture enclosure
• The ballast provides automatic lamp disconnection on failure; do not bypass protection circuits

Compliance

• EN 55015 (EMC emissions)
• EN 61000-3-2 (harmonic current)
• EN 61347-2-3 (electronic ballast safety)
• EN 61547 (EMC immunity)
• VDE 0710-T14
• EEI=A2 (Energy Efficiency Index)
• RoHS Compliant
• KEMA and ENEC certified
