  • Features

    The Philips Master Expert colour range has an ultra high colour rendering score of CRI97. This means it will reproduce colours just like they should be under normal daylight conditions. Expert colour LED lamps are ideal for use in museums, galleries, restaurants and in homes that want something better than the traditional CRI of 80.

    With a energy consumption of  5.5W, these GU10 LEDs offer a low energy alternative to the now banned 50W halogen. They are the same physical size as traditional halogen and will fit inside existing or new downlight housings. Featuring the very latest LED technology known as COB (chip on board), this single high power chip provides a higher level of light output and produces even less heat than previous models.

    After testing these Philips Expert colour lamps, they offer the closest match to halogen that we've seen. Dimmable as standard but also operates perfectly well in none dimming circuits with a standard on/off light switch.

    Q) Which colour temperature is best?

    A) The 2700K extra warm white tone is more orange in appearance, with a similar warm glow to a halogen or a standard incandescent light bulb. Warm white 3000K is clearer and slightly brighter, 3000K is the new norm for general lighting. The 4000K cool white has an ultra white, clinical appearance, a bit like the sky on a clear day. 4000K is more frequently used in commercial applications or when a more modern feel is required.

    Product Questions & Answers

    Set Descending Direction
    What is the IP rating for these bulbs. Are they suitable for outdoor wall lights.
    Question by: Lisa Freeman on 10 Nov 2022, 07:59
    They don't have any IP rating. If you fit them in a wall light, the wall light should be IP44 or above which means its water resistant.

    If you have a wall light in mind, we can double check.
