Satco S39720 Led T5 Linear Lamp 25W 6500K 3400 Lumens

Product Description

The SATCO S39720 is a 25-watt T5 LED linear lamp designed as a Type B ballast bypass replacement for fluorescent T5 fixtures. It produces 3400 lumens at a 6500K color temperature, delivering a daylight-quality output suited to commercial and industrial environments. The frosted lamp uses an aluminum construction and a miniature bi-pin base, and it supports both single-ended and double-ended wiring configurations, giving installers flexibility during retrofit work. With a rated lamp life of 50,000 hours and a CRI of 83, this lamp reduces maintenance cycles while maintaining acceptable color rendering for most commercial applications.

This lamp targets commercial interiors where fluorescent T5 strip fixtures, high-bay troffers, or undercabinet industrial fixtures are being converted to direct-wire LED operation. It is appropriate for office spaces, warehouses, retail back-of-house, and similar environments. Because it is a Type B direct-wire lamp, the existing ballast is bypassed during installation, eliminating a common point of failure and improving long-term energy efficiency. Licensed electricians typically handle this conversion in compliance with local electrical codes.

Compatibility

Designed as a direct-wire Type B replacement for T5 fluorescent lamp fixtures. Compatible fixture wiring must be reconfigured to bypass the existing ballast prior to installation. No specific model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

This is a Type B ballast bypass lamp and requires a licensed electrician to rewire the fixture for direct line-voltage operation before the lamp is installed. Always de-energize the circuit at the breaker and verify absence of voltage with a meter before opening the fixture. Do not install this lamp into a fixture that still has an active ballast connected, as this will damage the lamp and create a safety hazard. Work must comply with applicable NEC requirements and any local amendments.
