GE CFL Bulb ([21303]) is the 21W / 2700K version. This model is for a fitting designed around this compact fluorescent lamp format. The keyed base and available lamp space are important when replacing a lamp in a downlight or task fitting.
The G10q-4 base must match the exact keyed lampholder; a different pin arrangement is not interchangeable. In the lit area, 2700K supports a warm white lighting scheme. It describes the colour of the light rather than how bright the space will be. The fitting’s ballast must be rated for this model and its lamp wattage.
Buying tip: Check the existing socket for the G10q-4 base and compare the available clearance with the lamp dimensions.
