Product Description 

The ShopwithSIA Power-Backup Series presents the 20W Dual-Battery Bulb, the ultimate solution to Pakistan's load-shedding challenges.

Key Features & Benefits:

• Double Battery Power: Unlike cheap single-battery alternatives, this model comes with two 18650 lithium batteries. This ensures a brighter output and a more stable 4-hour runtime during long outages.

• Seamless AC/DC Function: Use it daily in your B22 socket. It charges while the light is on and triggers its "Emergency Mode" the moment the power fails. No manual switching required.

• Portable "Magic" Lighting: Want to take the light to another room or outside? Simply unscrew the bulb and attach the included Conductive Hook Cap. The bulb will light up instantly, becoming a handheld lantern for car repairs, camping, or night walks.

• Intelligent Auto-Charging: The built-in smart circuit prevents overcharging. A full charge takes 6–8 hours (or roughly 11 hours during regular use), and the bulb stops drawing charging current once the batteries are full.

• High Brightness 20W Output: Replaces standard energy savers with a powerful 20W LED chip that illuminates entire rooms, making it ideal for foyers, shops, and wedding hall backrooms.

• Rugged & Safe: Designed with a flame-retardant body and high-quality heat dissipation, ensuring the batteries stay cool during the charging cycle.
