Aquael Leddy Slim 5w Sunny White 20-30cm

Description

Aquael Leddy Slim 5w Sunny White 20-30cm — Compact daylight LED bar for nano freshwater tanks

A nano tank still needs proper daylight colour, not just enough light to see the fish by, and most lamps built for this are either too dim or scaled down from a fixture meant for a much longer tank. Aquael Leddy Slim 5w Sunny White 20-30cm (SKU: 102412) is the smallest size in Aquael’s Leddy Slim Sunny line, built specifically for open freshwater tanks around 20 to 30 cm long, running the Sunny spectrum at roughly 6,500 K for general daylight viewing rather than the growth-biased Plant spectrum sold alongside it in the same range. At 5 W, power draw is matched to a nano tank’s small water volume rather than oversized for it.

The flat housing sits directly on the glass rim on universal sliding brackets, which adjust within the 20 to 30 cm range to fit both standard and slightly non-standard tank widths. Aquael’s own description of the Sunny line notes that proper lighting matters for both the visual appeal of fish and plant colours and, where live plants are kept, for the photosynthesis they need, though light intensity requirements vary by species and this 5 W size suits a nano community tank rather than a demanding high-light aquascape. Aquael describes the Sunny version’s self-repair design as neighbouring diodes picking up a failed LED’s share of output at increased power, rather than the backup-LED approach used on the Plant version, so a single diode failure does not simply leave a dark patch in the lamp.

Usage & Application

When to Use

• Nano freshwater community tanks: Open tanks around 20 to 30 cm long needing daylight colour rather than plant-growth bias.
• Desktop or betta setups: A compact fixture matched to a small footprint and low power draw.
• Low-light or no-plant tanks: Where general viewing colour matters more than a growth-biased spectrum.
• Replacing a basic hood light: Upgrading a nano tank’s stock lighting to an LED bar.

How to Use / Installation Process

• Extend the brackets to the rim: Adjust the sliding arms to the tank’s width before fitting the lamp.
• Run a consistent daylight timer: 8 to 10 hours suits most community nano tanks as a starting point.
• Keep the lens clean: Wipe down regularly to maintain full output in a small, closely viewed tank.
• Pair with a Plant lamp if growing plants: Add the matching Plant version for photosynthesis-focused light rather than relying on Sunny alone.
