Philips EFR 6423FO halogen reflector

The Philips EFR 6423FO is a 150 watt halogen reflector bulb operating at 15 volts with a GZ6.35 base. It produces a colour temperature of 3350K and a colour rendering index of 100 for accurate colour reproduction. The rated life is 50 hours. It is designed for specialised equipment rather than general lighting.

Suits medical, dental and optical instruments

This bulb fits microscopes, projectors, fibre optic illuminators and medical or dental devices that require the EFR 6423FO specification. It is not suitable for standard household fixtures or mains voltage fittings. Buyers needing a longer service life or lower heat output should consider alternative technologies not covered by this product.

50 hour rated life at full output

The 150 watt filament delivers full intensity for the rated 50 hours before replacement is required. High colour fidelity is maintained throughout that period. Continuous operation beyond the rated hours will result in reduced output and eventual failure. The 15 volt supply must be regulated to achieve the stated lifetime.

Questions about this item

What fixture or device do I need to accept the GZ6.35 base on this 150 W 15 V halogen reflector?

The GZ6.35 bi-pin base fits sockets designed for MR16 lamps in medical, dental, projector, microscope or fibre-optic illuminator equipment that supply 15 V and can handle 150 W.

Can I run this EFR 6423FO alongside older 15 V MR16 lamps rated at lower wattage on the same power supply?

Each lamp draws its rated power; a 150 W lamp will demand more current than lower-wattage 15 V MR16 types, so the supply and wiring must be sized for the highest wattage installed.

How can I verify the bulb is delivering its specified 3350 K colour temperature and CRI 100 after installation?

Measure the light output with a calibrated spectrometer or colour meter; it should read approximately 3350 K correlated colour temperature and a colour rendering index of 100 when operating at 15 V.
