The S8356 from Satco is a 42W T4 compact fluorescent lamp designed for fixtures that use a GX24q-4 base. It produces 3,200 lumens at a cool 4100K with a CRI of 82. Key features include a 360-degree beam angle and a 15,000-hour rated life.

Key Features and Benefits of This Compact Fluorescent Lamp

At 3,200 lumens from 42 watts, this lamp gives strong brightness for its wattage. The 4100K color is a neutral white that suits work and utility areas. The 360-degree beam spreads light in all directions, and the 15,000-hour rated life reduces how often you change lamps.

Where to Use the S8356 Compact Fluorescent Lamp

This lamp is well suited as a replacement in existing fixtures made for a GX24q-4 base and T4 compact fluorescent lamps, such as general ambient lighting in indoor spaces. The page does not list a location rating, so confirm the fixture's environment before using it in damp areas.

Installation and Compatibility Checks

The lamp measures 6.59 inches in overall length and 2 inches in maximum diameter, so check the fixture clearance. Match the GX24q-4 base exactly. Voltage and dimming compatibility are not listed on the page, so confirm them on the specification sheet and do not assume it dims.

Additional Buying Context

Satco provides a 2-year manufacturer warranty, and the lamp is RoHS compliant. Since 4100K is a neutral white, choose a lower number for a warmer look. Compact fluorescent lamps are a direct replacement choice only when the fixture is designed for them.
