Description
Aquael Leddy Slim 36w Plant White 100-120cm — Largest LED bar in the Plant line for tanks up to 120 cm
Planting a tank past 100 cm long tests a lamp’s reach, and a unit built for a shorter length leaves the far corners noticeably dimmer than the centre once stretched to its limit. Aquael Leddy Slim 36w Plant White 100-120cm (SKU: 102417) is the largest size in Aquael’s Leddy Slim Plant line, built for open freshwater tanks from 100 to 120 cm long (Aquael’s spec sheet extends the sliding brackets to 127 cm), with enough diodes across its length to keep the Plant spectrum’s roughly 8,000 K output even from end to end rather than concentrated toward the middle. As with the smaller Plant sizes, the red and blue wavelengths are emphasised over green, the balance Aquael aims at photosynthesis rather than at brightening the water for viewing alone.
The lamp mounts on universal sliding brackets that extend to the tank’s full rim width, including custom lengths within its range, and because this is the 36 W size, it is also built to work with the Leddy Slim Hanger kit for ceiling suspension, letting it hang clear of tall stem plants, driftwood or hardscape that break the surface. Aquael’s Plant-version self-repair design uses backup LEDs that stay inactive in a new lamp and switch on automatically if a primary diode fails, so output stays consistent rather than dimming unevenly as the unit ages over a long-length lamp with more diodes to maintain. Plant light requirements vary widely by species, and a 100 to 120 cm tank run at this wattage can support a broad mix from carpeting foreground plants to taller background stems, provided CO2 and nutrients are kept in step with the light.
Usage & Application
When to Use
- Large planted display tanks: Open freshwater aquariums from 100 to 120 cm long.
- Dense or carpeted aquascapes: Layouts needing even light across the full tank length.
- Replacing twin fluorescent planted tubes: Moving a long tank from T5/T8 fluorescent to one LED bar.
- Tanks with tall hardscape: Suspending the lamp above driftwood or stem plants that reach the surface.
How to Use / Installation Process
- Extend both brackets near their limit: A 100 to 120 cm tank needs the sliding arms close to full reach.
- Keep CO2 and nutrients matched to the light: A long, growth-biased lamp run without them can push algae ahead of plants.
- Check rim support on long tanks: Thin glass or acrylic may need extra bracing under a full-length lamp.
- Fit the 36 W hanger kit if suspending: Lift the lamp clear of tall plants or hardscape rather than resting it on the rim.
