For your reference, here are the precautions when using the bulb:
1. Ensure that the power is turned off before installing, removing, or checking the bulb;
2. Do not use the bulb on the lamps provided with a dimmer (e.g., desk lamps featuring round dimmer switch) to prevent damage to the bulb;
3. Do not use the bulb in a humid environment;
4. Do not use the bulb in a lampshade that is narrow and poorly ventilated, as this could lead to signal attenuation or heat dissipation problems;
5. Make sure the voltage is consistent with the bulb's operating voltage before use. Using the bulb at a voltage other than the specified voltage may damage it and cause safety hazards;
6. Do not disassemble the bulb;
7. The bulb will generate heat during operation. Avoid using it in an enclosed holder for an extended period of time. Ensure proper ventilation to facilitate heat dissipation of the bulb;
8. The bulb is intended for indoor use only;
9. Disconnect the power supply before installation to prevent the risk of electric shock;
10. Do not use the bulb near water sources;
11. Do not use the bulb and dimmer together;
12. The light source of the bulb is a non-replaceable light emitting diode (LED);
13. The increased weight of the lamps with a significantly greater weight than the replacement lamp may potentially compromise the mechanical stability of the lamps;
14. The bulb cannot be used at emergency exits or as an emergency light.
