The bulb uses SMD LED technology behind a prismatic polycarbonate diffuser, which spreads the light evenly across the beam and reduces harsh shadows compared to clear-lens GU10s.\u003c\/p\u003e\n\u003cp\u003eDesigned as a direct replacement for halogen GU10 spotlights in domestic and commercial downlighters, track lights and adjustable ceiling fittings, the bulb runs on 230V mains without requiring a transformer. The dimmable design works with most trailing and leading edge dimmer switches, allowing light levels to be adjusted from full brightness down to a low glow for ambient evening lighting.\u003c\/p\u003e\n\u003cp\u003eThe 645lm output is comparable to a 50W halogen GU10 while consuming only 5W, giving an efficacy of 116.43lm\/W. The 3000K colour temperature sits at the warm end of the white spectrum, producing a soft yellow-white light that suits living rooms, bedrooms, hospitality spaces and dining areas. The polycarbonate body measures 50mm diameter by 54mm height, fitting standard GU10 lamp holders without protruding excessively from recessed downlighters.\u003c\/p\u003e\n\u003cp\u003eThe bulb carries an IP20 rating for dry indoor use only and is rated to 25,000 hours L70B50 lifespan, meaning 50% of bulbs in a batch will still deliver at least 70% of their initial lumen output after 25,000 hours of use. The colour rendering index exceeds CRI 80, providing adequate colour accuracy for most residential and commercial applications.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e54 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiffuser\u003c\/td\u003e\n\u003ctd\u003ePrismatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Technology\u003c\/td\u003e\n\u003ctd\u003eSMD LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eGU10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eYes*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eL70B50\u003c\/td\u003e\n\u003ctd\u003e25000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating (Class) post 2021 SLR\u003c\/td\u003e\n\u003ctd\u003eD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e3000 K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Colour\u003c\/td\u003e\n\u003ctd\u003eWarm White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens\u003c\/td\u003e\n\u003ctd\u003e645 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e116.43 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_6134776_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bulb compatible with dimmer switches?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the bulb is dimmable and compatible with most trailing and leading edge dimmer switches.
