Small planted or nano tanks don't need a full-size aquarium light overpowering the space, but they still need enough spectrum and intensity to grow plants well. The Dymax Flexz series — in 3, 5, and 7-inch lengths — scales lighting to match tank size instead of forcing a one-size-fits-all fixture onto every setup.
Why Size-Matched Lighting Matters
An oversized light on a small tank wastes energy and can push plant growth (and algae) faster than the tank's other parameters can keep up with; an undersized light on a larger tank leaves plants stretching for insufficient light. The Flexz series solves this by offering graduated lengths rather than one fixed size.
Choosing a Length
- Flexz 3 — sized for small planted or nano tanks that don't need a full-size fixture overpowering the space.
- Flexz 5 — a mid-size step up for tanks needing more coverage without moving to a full-size light.
- Flexz 7 — built for larger planted or reef tanks needing enough width to light the full tank evenly.
What the Series Offers
- Tunable spectrum and brightness across the lineup for planted and reef applications.
- Compact, low-profile design that suits nano and small-to-mid tank aesthetics.
- Consistent design language across sizes, so you can size up later without a mismatched look.
