Designed as a direct fluorescent replacement, this tube operates in ballast bypass mode, meaning the existing fluorescent ballast is removed and the fixture is rewired to run line voltage directly to the lamp holders. Supporting both single-ended and double-ended wiring configurations, it gives installers flexibility to match the bypass method to the fixture type on hand. Licensed electricians and commercial lighting contractors are the primary installers for this type of retrofit.\u003c\/p\u003e\n\u003cp\u003eThis tube is suited for commercial and light industrial applications including offices, warehouses, retail spaces, schools, and parking structures where T8 fluorescent lamps are being phased out. The 4000K color temperature is a common specification for task and general ambient lighting in commercial interiors. At 17 watts replacing a standard 32-watt T8 fluorescent, the energy reduction is significant for facilities running large quantities of fixtures. The glass construction provides a light output profile comparable to traditional fluorescent tubes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e17-watt input power delivers 2200 lumens at 4000K neutral white\u003c\/li\u003e\n  \u003cli\u003e80 CRI minimum for accurate color rendering in work environments\u003c\/li\u003e\n  \u003cli\u003eBallast bypass design eliminates ballast failure callbacks and ongoing ballast replacement costs\u003c\/li\u003e\n  \u003cli\u003eSingle-ended and double-ended wiring support gives installers configuration flexibility\u003c\/li\u003e\n  \u003cli\u003eGlass tube construction for a traditional T8 light distribution pattern\u003c\/li\u003e\n  \u003cli\u003e4-foot nominal length fits standard T8 fixture tombstones\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct ballast-bypass replacement for 4-foot T8 fluorescent lamp positions in standard bi-pin (G13) lamp holders after fluorescent ballast removal and fixture rewiring.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBallast bypass installation must be performed by a qualified electrician in accordance with NEC requirements, as line voltage is present at the lamp holders after conversion. De-energize the circuit at the breaker and verify zero voltage with a meter before removing the ballast or rewiring tombstones. Follow the manufacturer wiring diagram for the selected single-ended or double-ended configuration, as incorrect wiring can create a shock hazard or damage the lamp. Shunted tombstones must be replaced with non-shunted tombstones for single-ended wiring configurations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e: 17 watts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLumens\u003c\/strong\u003e: 2200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Temperature\u003c\/strong\u003e: 4000K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCRI\u003c\/strong\u003e: 80 minimum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLamp Type\u003c\/strong\u003e: T8 Linear LED\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 feet (48 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Glass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiring Configuration\u003c\/strong\u003e: Single-ended and double-ended ballast bypass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RAB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T8-17-48G-840-SD-BYP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RAB","offers":[{"title":"Default Title","offer_id":51383522001202,"sku":"T8-17-48G-840-SD-BYP","price":29.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673671.png?v=1782599301","url":"https:\/\/voomisupply.com\/products\/rab-t8-17-48g-840-sd-byp-17w-t8-led-tube-4ft-4000k-bypass","provider":"Voomi Supply","version":"1.0","type":"link"}
