Satco S19958 18W T5 LED Tube 3500K

18W T5 LED Tube Light, 3500K, by Satco

The S19958 from Satco is an 18-watt T5 LED tube designed to replace a 39-watt fluorescent T5 lamp. It is suitable for damp-location fixtures that take a G5 base. Key features include 2,500 lumens of 3500K light, dimmable operation, and a 50,000-hour rated life.

Key Features and Benefits of This LED Tube

Drawing 18 watts instead of 39, this tube cuts energy use compared with the fluorescent lamp it replaces. The 50,000-hour rated life means fewer replacements in hard-to-reach fixtures. Neutral white 3500K sits between warm and cool, which works well in work and display areas.

Where to Use the S19958 LED Tube

This tube is well suited for indoor fixtures that use T5 lamps, where the fixture is built for T5 lamps and a damp location rating is acceptable. It is rated IP20 and damp location, so it is not suitable for wet areas, direct water exposure, or outdoor use. Operating range is -20°C to 45°C.

Installation and Compatibility Checks

The lamp is 33.86 inches long with a G5 base. Page data does not state voltage or whether it works with your existing ballast or driver, so verify compatibility with your fixture before ordering. Dimming requires a compatible dimmer, and pack quantity is not listed.

Additional Buying Context

The tube is cULus Listed, RoHS and FCC compliant, and backed by a 5-year manufacturer warranty. If you are retrofitting old fluorescent fixtures, ask your electrician whether the ballast needs to be bypassed or replaced, as requirements vary by fixture.
