3. Safety Information
- Ensure power is turned off before installing or removing the bulb.
- Do not use with standard dimmers. This bulb is non-dimmable and requires a 3-way lamp socket for its multi-level brightness function. Using it with a conventional dimmer may cause damage or improper operation.
- Suitable for indoor use only.
- Do not disassemble the bulb.
- Avoid direct exposure to water or excessive humidity.
4. Setup and Installation
- Verify Compatibility: Ensure your lamp fixture has an E26 standard base and is equipped with a 3-way socket to utilize all three brightness levels. If used in a standard (non-3-way) socket, the bulb will operate at a single brightness level (approximately 10W equivalent).
- Power Off: Before installation, turn off the power to the lamp fixture at the switch or circuit breaker.
- Insert Bulb: Carefully screw the TORCHSTAR 3-Way LED Bulb into the E26 socket until it is snug. Do not overtighten.
- Restore Power: Turn the power back on.

- First Click: Activates the lowest brightness level (5W, 450lm), suitable for a relaxing atmosphere or night light.
- Second Click: Activates the medium brightness level (10W, 800lm), ideal for general lighting.
- Third Click: Activates the highest brightness level (16W, 1600lm), perfect for reading or task lighting.
- Fourth Click: Turns the bulb off.
