Description
Product Details

The OSRAM DULUX S 5W/840 compact fluorescent lamp (colour code 840) is a low-energy lamp with a single (2 tubes) tube and a G23 base. It emits cool white light at 4,000 K and about 250 lumens, with good colour rendering (CRI 82).

A non-integrated lamp (no built-in ballast), it fits G23 CFL luminaires and runs at 230 V through the fitting's ballast: 2-pin (magnetic ballast, integrated starter). Its long life (≈10,000 h) and low consumption make it an economical choice for commercial lighting.

Direct cross-references from other manufacturers: PHILIPS MASTER PL-S 5W/840/2P, GE Biax S 5W/840, SYLVANIA LYNX-S 5W/840. Same G23 base and same colour code 840: it replaces them without any change to the fitting.

Frequently asked questions

Is it compatible with my fitting?

Yes, if the fitting has a G23 base, the same wattage (5 W) and the right ballast. This is a non-integrated lamp: it needs the fitting's ballast and does not connect directly to the mains.

What is the PHILIPS, GE Lighting or SYLVANIA equivalent?

This lamp directly matches PHILIPS MASTER PL-S 5W/840/2P, GE Biax S 5W/840, SYLVANIA LYNX-S 5W/840. Identical G23 base, 5 W wattage and 840 colour code: a like-for-like replacement.

What is the difference between 2-pin and 4-pin?

The 2-pin version has a built-in starter and runs on a magnetic ballast. The 4-pin version runs on a high-frequency electronic ballast (fast start, flicker-free, often dimmable). Bases differ: match the one in your fitting.

What does the 840 code mean?

The first digit (8) indicates a CRI of 80 to 89; the next two give the colour temperature: 840 = 4,000 K (cool white).

How is it recycled?

Like all fluorescent tubes, it contains a small amount of mercury: take it to a WEEE collection point (recycling centre or store), never with household waste.
