Sleek aesthetics and class-leading efficiency combine in the MASTER LEDbulb range of replacement LED GLS light bulbs from Philips. Features a ES-E27 Edison screw (27mm) base/cap. Also known as an A60 light bulb.The example pictured here consumes just 8W and retrofits to any existing Edison Screw fixture. It is particularly effective in large-scale assemblies that require constant illumination such as corridors, hotel lobbies and staircases, where the full potential of its efficiency can be realised.The light bulb\'s unique optical design lends it an attractive appearance when turned off while emitting an inviting, warm white glow in all directions when turned on. This makes it incredibly popular among the hospitality industry, as does its extensive compatibility with a range of leading and trailing edge dimmer switches.Traditional light bulbs have a tendency to shift towards a warmer colour as they dim, while LED traditionally maintains the same colour. DimTone technology successfully mimics this behaviour while delivering all the efficiencies and reduced maintenance costs associated with LED.The aesthetic appeal of this range of LED light bulbs manages to bridge the gap between form and function, a feat rarely achieved with LED technology. In designing an optical lens that manages to make a functional product physically appealing, Philips have created a light bulb that we actually want to buy, rather than simply need to.This GLS is a newer product from Philips and supercedes their old GLS part codes: 8718696481325.Please visit the manufacturer\'s website for up-to-date dimmer switch compatibility lists for this Philips LED GLS light bulb before purchase.To find the answers to some common questions about LED dimming, please read our guide Dimming for Dummies.Need more help in choosing a suitable light bulb?
