Coral Sun is a high intensity actinic lamp with strong emissions in the short wavelength region of the spectrum, peaking at 420nm.
It promotes growth of zooxanthellae algae, essential for the growth and well being of all photosynthetic corals and invertebrates.
This bulb simulates the short wavelength blue light which penetrates to reef depth in nature.
Output closely matches the absorption peak of chlorophyll used in photosynthesis. Ideal for all marine aquariums or reef tanks.
Zoo Med's line of fluorescent aquarium lamps are made in Europe for ultra high quality, color, and longer burn life.
NB Beacuse of Royal Mail size restrictions you can not select "Special Delivery or Standard Delivery" as the shipping method for tubes over 30inches long, they must be sent by courier, if you live in the more remote parts of the UK or off-shore islands this will be very expensive.
