HL13S

One Spectrum. Nothing to Fiddle With.

The HYDROLIT HL13S is a clip-on nano light with a single job: put clean, plant-usable daylight over a small tank and stay out of the way. Its 32 LEDs run a fixed 6500K natural daylight spectrum at 1400 lumens — no modes to cycle, no settings to get wrong. Clamp it to the rim, bend the gooseneck to aim it, and it looks the same every day.

Why You'll Love It

• Fixed 6500K daylight spectrum — a clean neutral white tuned for plant growth and a clear, natural-looking tank.
• 1400 lumens from 32 LEDs — real output for a nano tank, from a fixture that takes up almost no visual space.
• Bendable gooseneck arm — a 280 mm (11 in) arm — rigid below, flexible above — so you can set height, angle and tilt by hand.
• Clamps to the rim — fits rimless glass up to 14 mm (0.55 in) with a single fixing screw.

Daylight, Not a Color Cast

A fixed 6500K spectrum is the simplest way to make a small tank look right. Plants get usable growth light, fish and hardscape keep their real colors, and there is no mode you might leave on the wrong setting. For a betta jar, a shrimp tank or a desktop scape, this is usually all the light you need.

An Arm That Holds Its Aim

The arm measures 280 mm (11 in) installed and comes in two sections: a rigid lower support that holds its position, and a flexible gooseneck above it that you bend to set height, angle and tilt. The clamp opens for rims up to 14 mm (0.55 in) and closes with a single screw — snug is enough, there is no need to torque it against glass.

Small Fixture, Small Footprint

The panel is 13 × 7 cm and the whole fixture disappears against a rimless tank. The clamp sits on the back rim and the cord runs down behind it, which keeps the front glass clear — the part you actually look at.

HL13T

Four Looks for a Small Tank.

The HYDROLIT HL13T is the tunable clip-on in the range: 18 RGB LEDs, four preset spectrum modes, stepless dimming and an 8-hour timer, all driven from one button. Switch from a growth spectrum to a display look to a dim moonlight without touching an app, and let the timer run the photoperiod for you. The gooseneck arm sets the aim; the clamp keeps it off the front glass.

Why You'll Love It

• Four preset spectrum modes — Full-Spectrum Growth, Color Enhancement, Lush Forest and Moonlight, cycled with one button.
• Stepless dimming — hold the button to sweep brightness; release and press again to reverse direction.
• 8-hour timer — double-click to arm it — the indicator flashes twice and stays lit to confirm.
• Bendable gooseneck arm — a 280 mm (11 in) arm, rigid below and flexible above, clamping rims up to 14 mm (0.55 in).

One Button, Four Scapes

Mode 1 Full-Spectrum Growth is the default for planted tanks. Mode 2 Color Enhancement pushes reds and deep greens when you want the scape on display. Mode 3 Lush Forest suits mossy and shaded layouts. Mode 4 Moonlight drops to a dim evening glow. No app, no pairing — just the power button.

An Arm That Holds Its Aim

The arm measures 280 mm (11 in) installed and comes in two sections: a rigid lower support that holds its position, and a flexible gooseneck above it that you bend to set height, angle and tilt. The clamp opens for rims up to 14 mm (0.55 in) and closes with a single screw — snug is enough, there is no need to torque it against glass.

Timer and Brightness, Without a Controller

Brightness is stepless: hold the button and the light sweeps through its range; release and press again to run the other way. The timer arms with a double-click and covers a fixed 8-hour photoperiod — enough structure for a nano tank without another box on the shelf. Note the timer can only be set while the light is on.

HL20T

A Wider Panel for a Bigger Nano.

The HYDROLIT HL20T takes the tunable clip-on format up a size: a 20 cm panel, 24 LEDs and 18 W putting out 1400 lumens. Four preset spectrum modes, stepless dimming and an 8-hour timer all run from one button, and the 280 mm gooseneck arm lets you set the aim by hand. It's the clip-on to reach for when a 13 cm panel no longer covers the scape.

Why You'll Love It

• 20 cm panel, 1400 lumens — wider coverage and more output than the 13 cm clip-ons, for tanks in the 30–40 cm range.
• Four preset spectrum modes — Full-Spectrum Growth, Color Enhancement, Lush Forest and Moonlight from one button.
• Stepless dimming and an 8-hour timer — hold to dim, double-click to arm the timer — no separate controller.
• Bendable gooseneck arm — a 280 mm (11 in) arm, rigid below and flexible above, clamping rims up to 14 mm (0.55 in).

One Button, Four Scapes

Mode 1 Full-Spectrum Growth is the everyday default. Mode 2 Color Enhancement deepens reds and greens for a display scape. Mode 3 Lush Forest suits mossy and shaded layouts. Mode 4 Moonlight drops to a dim evening glow. One button cycles all four — no app, no pairing.

The arm measures 280 mm (11 in) installed and comes in two sections: a rigid lower support that holds its position, and a flexible gooseneck above it that you bend to set height, angle and tilt. The clamp opens for rims up to 14 mm (0.55 in) and closes with a single screw — snug is enough, there is no need to torque it against glass.

Output That Reaches the Substrate

1400 lumens across a 20 cm panel is a real step up from a nano strip — enough to keep carpeting plants growing in a 30–40 cm tank rather than only lighting the top of the scape. Stepless dimming means you can back it off for low-light plants like Anubias, Bucephalandra and mosses.
