Description
The Eveready 58W T8 is a 1500mm fluorescent tube with a G13 bi-pin base, producing 5250 lumens at 3000K warm white colour temperature. The triphosphoric phosphor coating inside the frosted glass tube converts the mercury vapour discharge into visible light across a broader spectrum than standard halophosphate tubes, improving colour rendering and perceived brightness.
Designed for commercial, industrial and large residential spaces where fluorescent fittings are already installed, the tube fits standard T8 batten and modular fluorescent luminaires. Common applications include warehouses, workshops, offices, retail back-of-house areas, garages and utility rooms with 5ft twin or single tube fittings. The 58W power draw is typical for fluorescent tubes of this length and requires a compatible ballast rated for T8 58W operation.
The frosted finish diffuses the arc discharge and reduces the striping effect visible in clear fluorescent tubes, giving a more uniform spread of light along the 1500mm length. The tube weighs 230g and measures 26mm in diameter, which is the standard T8 profile. Energy rating G reflects the baseline efficiency of fluorescent technology compared to LED equivalents, but the tube remains a cost-effective replacement option where existing fluorescent infrastructure is in place.

Frequently Asked
What fitting does this tube require?
The tube has a G13 bi-pin base and requires a T8 fluorescent batten or modular fitting with a compatible 58W ballast. It will not work in LED-ready fittings or fittings wired for direct mains connection without a ballast.
Can this tube be dimmed?
No. Fluorescent tubes are not dimmable unless used with a specialist high-frequency dimmable ballast, which is uncommon in standard commercial fittings.
What is triphosphoric coating?
Triphosphoric refers to the three-band rare-earth phosphor coating inside the tube, which converts UV light from the mercury vapour discharge into visible light. This coating provides better colour rendering and higher perceived brightness than older halophosphate coatings.
How long does the tube last?
Fluorescent tubes typically last 10,000-15,000 hours depending on switching frequency. Frequent on-off cycles reduce lifespan, so the tube performs best in applications where it remains on for extended periods.
