![]()
The Osram Dulux L 24W/830 Lumilux is a 24W single-ended long twin-tube compact fluorescent lamp engineered for commercial and institutional modular luminaires, shallow recessed downlights, surface-mounted fixtures, and task lighting in offices, retail, and hospitality environments. Delivering 1,800 initial lumens of 3000K warm white output at 80–89 CRI through a 2G11 4-pin base in a 317mm profile, this Lumilux-coated CFL provides a 20,000-hour rated service life — compatible with magnetic, electronic, and dimming ballast systems.

ADL Supply Expert Application & Replacement Guide
The Osram Dulux L 24W/830 is primarily specified by electrical contractors and facility maintenance teams for replacement in Dulux L-format modular luminaires, shallow recessed commercial downlights, under-cabinet task strips, and surface-mounted ceiling fixtures where the 2G11 base and 317mm long twin-tube format are the installed standard. The 2G11 4-pin base uses 11mm spacing between the two pairs of pins in a single-ended configuration — physically distinct from the GX24q compact quad-tube base, the 2G7 small single-tube base, and the G5 T5 linear base. This lamp is compatible with conventional magnetic ballasts, electronic ballasts (ECG), and dimming electronic ballasts, making it appropriate for both legacy magnetic-ballasted commercial fixtures and modern electronic systems. The listed compatible ballasts (GE 47534 B224PUNV-C, Sylvania QTP2X26CF/UNV/DM, Universal Triad C2642UNVME, Universal Lighting B224PUNV) are confirmed platforms for this lamp — verify the ballast specification sheet explicitly lists 24W 2G11 Dulux L as a compatible load. Per NEMA guidance for high-frequency electronic ballast applications, an end-of-life shutdown circuit is recommended to prevent the base overheating failure mode that can occur in rare abnormal end-of-life situations.
Before You Order
| Verify Before Ordering 2G11 Socket Required — Not GX24q, 2G7, or G5 | Confirm Ballast Rated for 24W 2G11 Dulux L | State Shipping Restrictions Apply Confirm your fixture socket is 2G11 — not compatible with GX24q, 2G7, or G5 sockets. Confirm your ballast is rated for 24W Dulux L 2G11 operation. Use ballasts with end-of-life shutdown protection per NEMA guidance. Confirm 3000K warm white matches your installation. Contains mercury — cannot be shipped to CA, CO, HI, ME, MN, OR, RI, or VT. |

Operation, Safety & Mounting Compliance
2G11 Base, Broad Ballast Compatibility & NEMA End-of-Life Warning
The 2G11 base is the standard single-ended base for Dulux L and Philips PL-L format long twin-tube compact fluorescent lamps — the 11mm pin-group spacing is specific to this base class and is not interchangeable with other CFL base formats. The Dulux L platform supports conventional magnetic ballasts as well as electronic and dimming ballasts, making it viable for both legacy and modern commercial fixture applications. Per NEMA guidance, high-frequency electronic ballasts should incorporate end-of-life shutdown circuitry to prevent the base overheating failure mode that can occur in rare abnormal end-of-life situations — this applies whether the ballast is used with this lamp or any other T5 or compact fluorescent lamp type.
Mercury Content & Disposal
This lamp contains mercury and must be recycled through a certified lamp recycling program in compliance with applicable federal, state, and local regulations — do not discard in standard municipal solid waste. This product cannot be shipped to CA, CO, HI, ME, MN, OR, RI, or VT.
