Energizer G13 22W 5ft LED Tube - 4000K Cool White

The Energizer G13 is a 22W 5ft LED tube delivering 2400 lumens of 4000K cool white light through a 170° beam angle, designed as a direct retrofit replacement for 58W T8 fluorescent tubes in commercial and educational settings. The tube fits standard G13 bi-pin fittings and ships with an LED starter to bypass or replace existing fluorescent ballasts during installation.

Designed for offices, schools, workshops and retail spaces where consistent overhead lighting is required, the tube provides 109 lumens per watt output with a non-dimmable driver. The 4000K colour temperature sits between warm and daylight tones, producing a neutral white that reduces colour shift in task environments without the clinical edge of 5000K+ daylight tubes. The 170° beam angle distributes light evenly across ceiling-mounted fittings without the directional pooling common in narrower-beam LEDs.

The tube uses full glass construction with a shatterproof protective coating over the outer surface, adding impact resistance in high-traffic areas where accidental knocks or vandalism are concerns. The IC driver inside provides flicker-free operation at mains frequency, reducing eye strain during extended use under artificial light. At 0.3kg the tube weighs less than half a traditional fluorescent equivalent, simplifying handling during relamping on ladders or scissor lifts.

The retrofit design allows the tube to work with most T8 fluorescent fittings after starter replacement, avoiding the need to rewire ceiling roses or replace entire battens. Energy rating F reflects the current EU scale recalibration where all LEDs sit in lower bands; the 22W draw replaces 58W fluorescent output with 62% reduction in running costs.

How does this tube fit existing fluorescent fittings?

The Energizer G13 tube fits standard T8 fluorescent battens with bi-pin sockets. An LED starter is included in the box to bypass the existing fluorescent ballast. Remove the old fluorescent starter, insert the LED starter provided, then fit the LED tube into the G13 sockets. Some installations may require the ballast to be removed entirely — consult a qualified electrician if unsure.

What's the colour temperature like compared to old fluorescent tubes?

At 4000K this tube produces a neutral cool white, sitting between the warmer 3000K tone of some domestic LEDs and the stark 6000K+ daylight tubes used in clinical settings. It closely matches the output of traditional cool white fluorescent tubes, making it a familiar replacement in offices and schools.

Is the tube shatterproof?

The tube uses full glass construction with a protective shatterproof coating on the outer surface. This reduces the risk of glass shards if the tube is dropped or struck, but it is not unbreakable. Handle with care during installation.

What's the expected lifespan?

Energizer does not provide an hours-rated lifespan in the supplied specification for this model. LED tubes of this type typically deliver 15,000-25,000 hours before reaching L70 depreciation (70% of initial output), but exact lifespan depends on ambient temperature and usage patterns.
