Wholesale FAQ

What is the minimum order quantity?

MOQ is 500 pieces. We support mixed orders across different wattages (5W/7W/9W) and color temperatures (3000K/6000K).

How does the automatic activation work?

The bulb senses the AC power supply. When power is present, it charges the internal battery and operates as a normal LED bulb. When power is interrupted, it automatically switches to battery mode within 1 second, providing continuous lighting.

How long does the battery last during a power outage?

The 1200mAh lithium battery provides 4-6 hours of continuous illumination depending on the wattage. Lower wattage models (5W) provide longer backup time, while higher wattage models (9W) provide brighter output but shorter duration.

How long does it take to recharge?

Full recharge takes 6-8 hours of normal operation. The battery maintains its charge during regular use, so it is always ready for an emergency.

Can it be used with a switch?

Yes, the bulb works with standard wall switches. When the switch is on, it operates as a normal light and charges the battery. When the switch is off, it enters standby mode. During a power outage, the bulb will activate only if the switch was in the on position.
