GR10q 4 Pin 16W 3500K CFL Bulb

The essentials

This compact 4 pin CFL bulb delivers warm white light at 3500K for bathrooms and compact luminaires. Its flat butterfly shape allows even light distribution in slim fixtures, making it suitable for flush ceiling fittings and other tight spaces. With AC 230V operation, the GR10q bulb is designed for reliability in everyday home lighting, offering stable illumination without dimming capabilities.

The bulb measures 13.3 by 13.3 centimetres, a compact footprint that fits smaller ceiling spaces while still providing bright, practical illumination. It is essential to confirm ballast compatibility before installation, as 4 pin GR10q bulbs require a ballast and cannot be used with 2 pin fixtures. This keeps maintenance straightforward and reduces the risk of installation issues.

For trouble free performance, note that this bulb uses a 4 pin GR10q connector and is not compatible with 2 pin ballasts. It is part of a practical, energy saving lighting solution for bathrooms and other utility areas where a slim profile is advantageous. If you need a larger 28W alternative, this exact model will not fit the ballast or size requirements. The design prioritises durability and straightforward use in everyday settings.

Overall, the GR10q 4 pin bulb combines compact size with dependable light output, ideal for people upgrading existing bathroom lighting without reworking fixtures. Its warm white tone is well suited to bathrooms, hallways and kitchens where clear, comfortable illumination is valued. When installed with the proper ballast, you gain energy efficiency and a long service life that supports low replacement costs over time. 😊
