The SATCO S3427 is a 50-watt halogen lamp in a T4 tubular envelope. Halogen T4 lamps operate on a tungsten-halogen cycle that extends filament life and maintains lumen output over the lamp's rated life. The compact T4 profile makes this lamp suitable for task lighting, display fixtures, and under-cabinet luminaires where a small, high-output source is required. Licensed electricians and lighting technicians are the typical installers for fixtures requiring this lamp type.
The S3427 is used in residential and light commercial applications wherever a T4 halogen source is specified. Common install scenarios include track lighting heads, recessed accent fixtures, desk lamps, and cabinet lighting systems designed around the T4 form factor. Verify fixture wattage rating before installation to confirm the 50-watt load is within the fixture's rated capacity.
Designed as a replacement T4 halogen lamp for residential and light commercial fixtures specifying a 50-watt T4 source. Confirm fixture base type and wattage rating before installation.
De-energize the fixture and allow the existing lamp to cool completely before handling. Halogen lamps are sensitive to skin oils — handle with a clean cloth or the packaging sleeve to avoid contaminating the envelope, which can cause premature failure. Follow NEC guidelines for luminaire wattage ratings and fixture clearance to combustibles.
