Please read these instructions carefully before installation and retain them for future reference. The Satco S2401 is a 29-watt, 120-volt halogen light bulb designed for indoor use, featuring an E26 base and A19 shape, providing 430 lumens of cool white light at 2900 Kelvin.
2. Safety Information
- Always turn off power to the fixture and allow the bulb to cool before replacing.
- Do not exceed the maximum wattage rating of your fixture.

3. Installation
Follow these steps to properly install your Satco S2401 Halogen Excel Light Bulb:
- Ensure Power is Off: Before beginning, locate the light switch or circuit breaker controlling the fixture and turn off the power. This prevents electrical shock.
- Remove Old Bulb (if applicable): If replacing an existing bulb, carefully unscrew it counter-clockwise from the socket. Allow it to cool if it was recently in use.
- Prepare New Bulb: Remove the new Satco S2401 bulb from its packaging. It is recommended to handle the bulb by its base or with a clean cloth to avoid transferring oils from your skin to the glass, which can shorten bulb life.
- Insert New Bulb: Align the E26 screw base of the new bulb with the socket in the fixture. Gently screw the bulb clockwise into the socket until it is snug. Do not overtighten.
- Restore Power: Once the bulb is securely installed, turn the power back on at the light switch or circuit breaker.
- Test: Turn on the light switch to confirm the bulb is functioning correctly.
