ENER-J 10W Smart AI Inverter Bulb with Battery Backup — 1000 Lumens, 10+ Hours, 3-Step Dimming, B22

Power cuts in India aren’t a surprise — they’re just part of life. But that doesn’t mean you have to sit in the dark waiting for the grid to come back. The ENER-J F910 is an inverter bulb for home use that keeps right on glowing when the power goes out, switching to its built-in 1800mAh battery automatically — no flicker, no delay, no separate emergency light needed. Just screw it into any B22 holder and carry on.

Why This Smart Inverter Bulb Is Different

• Switches to battery automatically — instantly: The moment mains power fails, the F910 switches to battery mode without a single flicker. No manual intervention, no separate switch, no delay. The light stays on as if nothing happened.
• AI technology stretches your battery further: This is what makes the F910 smarter than a basic backup bulb. Built-in AI monitors the battery level in real time and automatically dims the light as the battery gets low — so instead of the light suddenly cutting out, it gently steps down and keeps going for longer. On low brightness, that’s 10+ hours of backup from a single charge.
• 3-step dimming via your existing switch: No app, no remote, no separate controller. Just use your existing on-off wall switch to cycle between full (1000 lm), medium, and low brightness — in both mains and battery mode. Practical and intuitive.
• Up to 10+ hours of backup on low brightness: Full brightness gives you 3–4 hours — enough for most outages. Medium gives 6–7 hours. Low brightness stretches past 10 hours — longer than almost any power cut you’re likely to face.
• Fits your existing B22 holder — no changes needed: Standard B22 bayonet fitting, A70 bulb size. Replace any regular bulb in any B22 socket and it’s done. No rewiring, no electrician, no new fittings.
• 1000 lumens — properly bright: At 10W and 1000 lumens, this is a genuinely useful light — not a dim emergency glow that barely lights a corner. It’s bright enough to work, read, and carry on normally during a power cut.
• Charges itself when mains power is on: When the grid is back, the bulb charges its internal battery automatically while continuing to light the room normally. Charging takes 4–6 hours to reach full capacity.
• Mercury-free, no UV/IR radiation, RoHS compliant: Completely safe for home use — in bedrooms, children’s rooms, kitchens, or anywhere else.
