The Light Bulb is a plant in Plants vs. Zombies Online. It lights up the entire lawn, but short circuits and disappears after a certain amount of time. It is the second plant obtained on Day 2 in the Industrial Revolution.


When first planted, Light Bulb will take a while to burrow out of the ground. Afterwards, it will turn on and light up the entire lawn. It lasts for a while, however it will eventually short circuit. When it does, it will slightly damage zombies in a 5x5 area and then disappear.

Light Bulb illuminates the entire lawn, but short circuits after a while.

Almanac Entry: Light Bulb is usually kind, carring, and loves being as bright as she can be! Although sometimes she gets a twitchy and starts short circuiting. It's nothing big, she'll just burrow undergound, and wait it out for a few seconds, and get back into the battlefield when she's ready to go! Just like that. She loves helping others so much she'll reanimate from the dead.
