The 2D configuration provides an even light distribution across its expanded footprint, making it particularly suitable for kitchens, living areas, retail environments, and hospitality settings where a low-profile aesthetic combined with ample brightness is desired. Operating with a compatible magnetic ballast (typical for 2-pin configurations), it produces a warm white light at 3500K, offering a softer, more inviting illumination that creates a comfortable and welcoming atmosphere.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eEngineered with a 2-pin base, this lamp is designed for straightforward installation in dedicated 2D fittings commonly found in both residential and commercial environments. With an average rated life of approximately 10,000 hours, it provides extended service life that reduces maintenance frequency and replacement costs. The non-dimmable operation ensures stable, flicker-free performance, making it a dependable choice for kitchens, living rooms, retail displays, office areas, and hospitality venues where consistent, energy-efficient lighting in a larger square form factor with a warm white tone is essential.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eKEY FEATURES\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eLarge Square 2D Design\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e: Expanded 198mm x 198mm footprint provides broad, even light distribution suitable for larger fixtures and spaces.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eEnergy-Efficient Operation\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e: Consumes only 28 watts, offering significant energy savings compared to traditional lighting alternatives.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eExtended Service Life\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e: Rated for approximately 10,000 hours of average use, minimizing lamp replacement frequency.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eWarm White Light\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e: Provides 3500K color temperature, offering a softer, inviting illumination ideal for residential and hospitality environments.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003e2-Pin Base Configuration\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e: Designed for fixtures requiring a 2-pin 2D connection, typically used with magnetic ballasts.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eTechnical Specifications\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv class=\"ds-scroll-area ds-scroll-area--show-on-focus-within _1210dd7 c03cafe9\"\u003e\n\u003cdiv class=\"ds-scroll-area__gutters\"\u003e\n\u003cdiv class=\"ds-scroll-area__horizontal-gutter\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ds-scroll-area__vertical-gutter\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cspan\u003eSpecification\u003c\/span\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cspan\u003eDetail\u003c\/span\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e\u003cspan\u003eWattage\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e28W\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e\u003cspan\u003eLamp Type\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2D Compact Fluorescent (Square)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e\u003cspan\u003eBase Type\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2 Pin\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e\u003cspan\u003eColor Temperature\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e3500K (Warm White)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e\u003cspan\u003eDimmability\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eNon-dimmable\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e\u003cspan\u003eAverage Rated Life\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eApprox. 10,000 hours\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e\u003cspan\u003eDimensions\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eLength: 198mm, Width: 198mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003ch3\u003e\u003cspan\u003eFrequently Asked Questions (FAQs)\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003e1.
