Simulate natural lighting conditions and help your students learn about marine biology with these long-lasting, high-quality bulbs.
The incandescent bulbs have heavy-duty filaments and are ideal for use with our reflectors and hoods. Fluorescent bulbs result in more vibrant colors in saltwater tanks. We recommend using the 45 cm bulbs for 15- to 20-gallon aquaria, and 121 cm bulbs for 55-gallon aquaria.
