Symban CFL Bulb (F21/2D/835/4P) is the 10W / 3500K version. In a compatible compact fluorescent downlight or other CFL fitting, this model should match the existing base and lamp envelope rather than only the stated wattage.
The G10q-4 base must match the exact keyed lampholder; a different pin arrangement is not interchangeable. For the lit area, 3500K offers a white-light appearance between warmer residential tones and cooler daylight colours. The fitting’s ballast must be rated for this model and its lamp wattage. Each ordered pack contains 20 units of this model.
Buying tip: Check the existing socket for the G10q-4 base and compare the available clearance with the lamp dimensions.
