Suitable for fixtures with conventional or electronic ballast

Fluorescent tubes require a ballast and fixtures either have a conventional (electromagnetic) one or an electronic one. It's easy to tell which type of fixture you have because ones with a conventional ballast require a starter too. If your fixture doesn't have a starter, then it has an electronic ballast. No matter what type of fixture you have, this fluorescent tube works with both.

Dimensions and wattage

This Philips TL-D Super 80 (MASTER) is an attractively-priced fluorescent tube that's 104.5 cm long and consumes 38 watts of power. This type of fluorescent tube is known as a T8. It's 28 mm in diameter and has G13 caps that make it easy to install in a suitable fixture.

Lifespan of 20,000 hours

This fluorescent tube has a lifespan of 20,000 hours. Fluorescent tubes often start to lose their light quality as they approach the end of their lifespan, but Philips has taken care to ensure that won't happen with this tube. It shows colours accurately too thanks to a score of >80 on the colour rendering index and a special coating.

Cool white - 4000K

A colour temperature of 4000K means that this tube emits a cool white light. This colour temperature is often chosen for use in offices, schools and industrial settings because it helps to keep people focussed and alert.
