Square 10W GR10q CFL 3500K Lamp

A 10W square-format compact fluorescent lamp with GR10q 4-pin base and 3500K warm white chromaticity. Measures 115 × 35 × 35 mm and weighs ~75g. Constructed with high-purity trichromatic phosphor coating and enhanced electrode architecture: each inner electrode includes a built-in protective ring to inhibit metal vapour deposition and delay end-blackening — a key contributor to lumen loss in standard CFLs. Delivers steady, flicker-minimised light ideal for prolonged visual tasks. Its warm white output supports circadian rhythm alignment in evening use and creates a relaxed environment in bedrooms, lounges or hospitality spaces. Energy consumption is reduced by roughly 80% compared to equivalent incandescent alternatives, aligning with UK household energy-saving goals. Fits seamlessly into existing GR10q-compatible luminaires found in UK homes, social housing units, schools and local authority buildings — offering an affordable, proven upgrade path from outdated lighting technologies without requiring infrastructure changes.
