LANDEN HYDROLIT HL20T Clip-On RGB LED Aquarium Light — 18W, 4 Modes, Dimmable, 20cm Panel

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 300 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 300 mm 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 is 300 mm in two sections: a 100 mm rigid lower support that holds its position, and a 200 mm 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.
