Philips Master LED ExpertColor LED bulb Cool white 4000 K 6.5 W GU5.3

Philips Master LED ExpertColor 6.5 W GU5.3 is a bi-pin low-voltage LED spot that delivers 460 lm of cool white light at 4000 K with very high color fidelity (CRI 97). Designed as an energy-efficient retrofit for MR16 halogen fixtures with a GU5.3 socket, this lamp provides a 36° beam angle suitable for directional and accent lighting in residential and commercial settings. The lamp has a long rated lifetime and a compact trimless appearance that integrates cleanly into many interior fixtures.

Advantages

The high color rendering index (CRI 97) ensures accurate reproduction of interior materials, textiles and finishes, making colours appear natural and detailed. With 6.5 W power consumption and luminous output comparable to ~35 W halogen equivalents, the LED reduces energy use while maintaining similar light levels. The trimless lens and narrow beam make it suitable for focused accenting, and compatibility with a wide range of low-voltage transformers supports smooth dimming performance.
