The Marineland LED Aquarium Light can be used to light a fish-only tank up to 30". The white LEDs create a shimmering light that mimics the natural underwater effect of sunlight. At night you can switch to the blue night light mode.

Features:

• 42 X White & 3 X Blue 60mW LEDs. Total watts: 2.52. Note: LEDs are much brighter per watt than other types of lighting.
• Dimension: 11" X 4" X 1"
• 3-position switch: On/Off/Blue
• The low-voltage AC adapter is energy efficient, saving money on your electric bill. LEDs do not contain mercury—making them better for the environment than traditional aquarium lighting.
• Designed to sit on top of a glass or clear plastic aquarium cover
