Square 16W Cool White Energy Saving Bulb

This square-shaped energy-saving bulb draws 16W and outputs over 2000 lumens at a consistent 3500K cool white colour temperature. It features a GR10q 4-pin base and utilises high-efficiency tri-phosphor technology for reliable performance and accurate colour representation. The compact square geometry allows seamless integration into modern troffer and panel light fittings. Its construction includes robust glass housing and internal electronics optimised for stable operation in continuous-use environments. With no warm-up delay and instant full brightness, it supports productivity-critical settings where immediate, uniform illumination is expected. Ideal for UK and EU-standard 4-pin GR10q installations—including suspended office ceilings, retail display zones, educational facilities, and domestic utility spaces like garages and kitchens—where long runtime, consistent output, and fixture compatibility are essential.
