Light Bulb

The Light Bulb is the fourth plant obtained in Victorian London. Light Bulbs illuminate a small area of fog and can be toggled off for various benefits.

Suburban Almanac Entry
Light Bulb is quite the switched on individual, a bright spark if you will. Believe it or not, his idea to use his powers of illumination to spot zombies in the thick London fog was revolutionary.

Plant Food
Permanently turns into a red animal light that is no longer toggleable. The red light will illuminate the fog without allowing the Fog-shroom to be eaten or the Werewolf Zombie to transform.

Strategies
The Light Bulb is the ideal fog-remover in Victorian London, but will allow the Fog-shroom to be eaten and the Werewolf Zombie to transform earlier while activated. However, the Light Bulb is the only thing that can allow the Thief Zombie to be targeted.

Use of the Light Bulb without plant food places limitations the Fog-shroom, a very powerful plant for the area. In levels with the Werewolf Zombie, either Mistletoe or a strong defence should be used if you plan to bring the Light Bulb. This is especially important for levels with the Thief Zombie.

Trivia

 * The Light Bulb is the second fog removing plant in the PvZ franchise.
 * The plant refers to the real-life electronic light bulb, where its toggleability is inspired by the toggleability of light bulbs in real life.
