Rated as a direct replacement for 35W halogen MR16 bulbs, the LED consumes 90% less energy while producing comparable light output on the same transformer or driver.\u003c\/p\u003e\n\u003cp\u003eDesigned for track lighting, recessed downlights and display lighting in both residential and commercial settings, the narrow 36° beam concentrates light onto worktops, artwork, shelving and reading positions without spilling excess light into surrounding areas. The 3000K colour temperature produces a warm incandescent-like tone that works across traditional and contemporary interiors, particularly in living rooms, bedrooms, kitchens and hospitality environments where a relaxed atmosphere is needed.\u003c\/p\u003e\n\u003cp\u003eThe bulb carries a 15-year lifespan rating based on 3 hours daily use, equating to approximately 16,425 hours before lumen depreciation becomes noticeable. The MR16 reflector body measures 50mm in diameter and 45mm deep, fitting standard recessed and surface-mounted MR16 luminaires without modification. The bulb operates on 12V AC or DC supply via a compatible LED driver or transformer, and the GU5.3 base uses the same 5.3mm pin spacing as halogen predecessors.\u003c\/p\u003e\n\u003cp\u003eThe non-dimmable circuit design prioritises reliability and efficiency over dimmer compatibility, making the bulb suitable for fixed installations where light level adjustment is not required. The narrow beam angle and moderate 345-lumen output suit task-oriented applications rather than general room illumination, where multiple bulbs in a track or grid arrangement provide coverage.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e3.4W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e345\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eSpot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eMR16 \/ GU5.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e3,000K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eWarm White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e36\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bulb dimmable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The bulb uses a non-dimmable LED driver circuit. Attempting to use it with a dimmer switch may cause flickering, buzzing or premature failure.

It requires a compatible LED driver or transformer rated for LED loads. Older halogen transformers may work but can cause compatibility issues — using an LED-rated driver is recommended for reliable performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it replace a 35W halogen bulb directly?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The 345-lumen output and 36° beam angle closely match a standard 35W halogen MR16, making it a direct retrofit in most applications. The GU5.3 base is the same pin spacing, so the bulb fits existing lamp holders without modification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the 36° beam angle mean in practice?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA 36° beam is classified as a narrow cone. It concentrates light onto a defined area approximately 1.2m wide when the bulb is positioned 2m from the surface, making it suitable for task lighting, accent lighting and directional applications rather than general room wash.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":46077996564747,"sku":"S8832","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S8832-Front-On_1938a611-cb0c-4797-9d76-a5a127e9a54f.jpg?v=1730381623","url":"https:\/\/niori.co.uk\/products\/energizer-3-4w-mr16-led-bulb-gu5-3-3000k-warm-white-non-dimmable","provider":"Niori","version":"1.0","type":"link"}
