What it is

The Crompton CIR40SPCW is a T9 circular fluorescent lamp rated at 40W with a 4000K colour temperature. It carries a triphosphor coating and terminates in a G10Q cap. The circular ring format is intended for luminaires built to accept a T9 circular tube.

Before you order

  • Confirm the luminaire is designed to take a 40W T9 circular fluorescent tube.
  • Check the existing lamp is 4000K so the colour temperature matches across the installation.
  • Verify the cap is G10Q and that the lampholder pin arrangement is compatible.
  • Check the physical size of the existing ring tube against the fitting before ordering.
