Designed as a direct ballast bypass lamp, it eliminates the ballast entirely, connecting line voltage directly to the tombstone sockets. The double-sided construction delivers a 180-degree beam angle per side, making it well suited for illuminated sign cabinets and channel letter applications. Rated for temperatures from -22 degrees F to 131 degrees F, this lamp handles demanding indoor and outdoor sign environments. Electricians and sign service technicians install this lamp in commercial and retail sign fixtures.\u003c\/p\u003e\n\u003cp\u003eThis lamp is intended for use in illuminated sign boxes, backlit display cabinets, and similar commercial signage applications where a long-format T8 LED source is required. The ballast bypass configuration means the existing ballast circuit must be removed and wired for direct line voltage — making this a permanent retrofit lamp. Its 96-inch length, 1.1-inch diameter, and T8 base format target standard 8-foot sign tombstone socket assemblies. The 120-277 volt input range covers both single-phase and commercial three-phase panel feeds without additional hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e42W ballast bypass design — removes ballast dependency for longer system life\u003c\/li\u003e\n  \u003cli\u003e5,300 lumens output at 6500K daylight color temperature for bright, high-contrast sign illumination\u003c\/li\u003e\n  \u003cli\u003eDouble-sided lamp construction with 180-degree beam angle for even cabinet lighting\u003c\/li\u003e\n  \u003cli\u003e96-inch (8-foot) T8 form factor, 1.1-inch diameter\u003c\/li\u003e\n  \u003cli\u003eWide voltage input range: 120 to 277 volts AC\u003c\/li\u003e\n  \u003cli\u003e50,000+ hour rated average life reduces maintenance intervals on hard-to-reach sign installations\u003c\/li\u003e\n  \u003cli\u003eTemperature rated from -22 degrees F to 131 degrees F for indoor and outdoor sign use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a ballast bypass retrofit for 8-foot T8 sign cabinet fixtures using standard tombstone sockets.

Disconnect and de-energize the sign cabinet completely before beginning any wiring work. The existing ballast must be removed and bypassed — do not attempt to run this lamp through an active ballast. Verify tombstone socket type and orientation are compatible with the lamp's base before energizing the circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e: 42W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLumens\u003c\/strong\u003e: 5,300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Temperature\u003c\/strong\u003e: 6500K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120-277V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBeam Angle\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBulb Shape\u003c\/strong\u003e: T8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 96 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Rendering Index (CRI)\u003c\/strong\u003e: greater than 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAverage Rated Life\u003c\/strong\u003e: 50,000+ hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -22 to 131 degrees F\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: KEYSTONE TECHNOLOGIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: kt-led42t8-96p2so-8csk-dx2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE TECHNOLOGIES","offers":[{"title":"Default Title","offer_id":51668806369586,"sku":"KT-LED42T8-96P2SO-8CSK-DX2","price":100.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e87f5e3d9650f2a4e968dce8c743cef5.jpg?v=1787952373","url":"https:\/\/voomisupply.com\/products\/keystone-technologies-kt-led42t8-96p2so-8csk-dx2-sign-tube-led","provider":"Voomi Supply","version":"1.0","type":"link"}
