LED 2D Lamps (GR10Q 4pin)

LED 2D lamps with a GR10Q 4-pin base, made as a direct retrofit for traditional 2D fluorescent (DD) lamps rated at 16W, 28W and 36W. They drop into existing ceiling and wall-mounted 2D fittings without needing a new fitting, so you can refurbish what's already installed rather than replace it.

Each lamp uses a perforated PCB for heat dissipation, which helps the lamp maintain output over a long service life. A built-in LED driver and standard 4-pin base keep them compatible with fittings already on the market. A microwave sensor version is available for extra savings where occupancy-based control makes sense.

The range also includes emergency conversion packs with Ni-Cd batteries, which connect to 12W or 16W trays to give maintained power supply if the mains fails. This is the section to check for replacement batteries and emergency modules alongside the lamps themselves.
