LANDEN HYDROLIT Clip-On LED Aquarium Light — 12W / 18W, 6500K Daylight or RGB, for Nano Tanks

Model Power LEDs Spectrum HL13S 12W 32 Fixed 6500K daylight HL13T 12W 18 RGB, 4 preset modes HL20T 18W 24 RGB, 4 preset modes, 20cm panel HL13SOne 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.

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.

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. 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. 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.
