T90 Series LED Aquarium Light

Light Coverage Guidance

Coverage guidance is based on full-power output and even light distribution.

• Single light
Recommended for aquariums approximately 24–36 inches long
(60–90 cm)

• Two lights
Recommended for aquariums approximately 36–48 inches long
(90–120 cm)

• Three lights
Recommended for aquariums approximately 59–71 inches long
(150–180 cm)

These ranges assume uniform lighting across the aquarium.
Using fewer fixtures over a larger aquarium can intentionally create varied lighting zones for mixed plant requirements and visual contrast.

Lighting zones and overlap
Using fewer fixtures than full coverage, allowing overlap between lights, or intentionally leaving shaded areas can create distinct lighting zones within an aquascape. This approach is useful for accommodating plants with different light requirements and can add depth, contrast, and a more natural visual balance to the layout.
