Description
Aquael Leddy Slim 10w Plant 50-70cm — Mid-size planted-tank LED bar with a growth-biased spectrum
A medium planted tank sits in an awkward spot for lighting: too long for the smallest nano lamps, too short to justify a full-length display fixture. Aquael Leddy Slim 10w Plant 50-70cm (SKU: 102415) is the 10 W size in Aquael’s Leddy Slim Plant line, built for open freshwater tanks around 50 to 70 cm long and running the Plant spectrum at roughly 8,000 K, with the red and blue wavelengths plants use for photosynthesis emphasised over the green that mainly serves human viewing. The lamp’s flat, low-profile shape sits directly on the glass rim and is finished in white or the matching black version sold elsewhere in the range, letting it blend with either a pale or dark aquarium setup.
Mounting uses Aquael’s universal sliding brackets, which adjust to both standard 50-70 cm tank widths and custom sizes within that range, and the lamp can also be suspended using the optional Leddy Slim Hanger set, built for the 32 W and 36 W sizes, rather than this 10 W unit, so a rim-mounted fit is the standard option here. Light intensity needed varies by plant species, and Aquael notes this directly: a carpet plant or a high-light stem plant may call for more output than a shade-tolerant species in the same tank, so the 10 W Plant lamp suits moderate planting rather than the most demanding high-tech setups. As with the rest of the Plant line, extra LEDs sit inactive inside the lamp when new and switch on automatically if a primary diode fails, so output does not simply fade as individual LEDs age over the unit’s service life.
Usage & Application
When to Use
- Medium planted tanks: Open freshwater tanks around 50 to 70 cm long.
- Moderate-light aquascapes: Stem and rosette plants that do not need the most intense high-tech lighting.
- Replacing a T5 planted tube: Moving a mid-size tank from fluorescent to LED without changing the stand.
- Custom tank widths: Universal sliding brackets fit non-standard sizes within the stated range.
How to Use / Installation Process
- Extend the brackets to the rim: Adjust the sliding arms to the tank’s width before fitting the lamp.
- Set the photoperiod to the planting: 8 to 10 hours suits most moderate-light setups; adjust for the species kept.
- Watch for algae with CO2 off: A growth-biased spectrum run too long without adequate CO2 or nutrients can favour algae over plants.
- Use the rim mount, not the hanger kit: Aquael’s Leddy Slim Hanger is built for the 32 W and 36 W sizes, not this 10 W unit.
