What it is

The Kosnic KLED12CRD/4P-W40 is a 12W LED replacement for 4-pin GR10q 2D fluorescent lamps, with an integrated microwave motion sensor and photocell built in. It is designed to retrofit directly into existing 2D/DD fittings with little or no rewiring, for corridor and stairwell lighting that only runs at full output when needed.

Signs this part needs replacing

  • Lamp fails to strike, flickers, or only glows dimly
  • Sensor no longer detects movement, or stays permanently on or off
  • Noticeably reduced light output compared to a new lamp
  • Blackening visible at the lamp ends through the diffuser

Before you order

  • Confirm your fitting takes a 4-pin GR10q 2D/DD lamp, not a 2-pin type
  • Check whether your fitting needs the sensor version or a plain lamp
  • Isolate the lighting circuit before replacing the lamp
