WEEK AQUA S Series RGB+UV Planted Aquarium Light — Full-Spectrum Clip-On LED

Full-spectrum RGB + UV colour, Bluetooth control, and a clip mount that aims exactly where you want it.

Bring your nano and mid-size scapes to life. The WEEK AQUA S Series combines high-output RGB with dedicated UV (UVA) LEDs to grow healthy plants and render deep, vivid colour — the reds glow, the greens pop, and the whole tank looks richer than it does under a plain yellowish light. A slim clip-on arm keeps the footprint tiny, while a 360°-rotating panel and tilting shade let you aim the light precisely. Run it all from your phone: preset modes, stepless RGB/UV dimming, and a natural sunrise-to-sunset day, all on Bluetooth.

Why Aquascapers Choose the S Series

• 🌈 RGB + UV full spectrum — balanced growth light plus UVA (~400nm) for deeper reds and sharper colour contrast
• 📱 Bluetooth app control — every S model connects to the WEEK AQUA app (all are 36V, no remote-only versions)
• 🎛️ Stepless 1–100% dimming — dial R, G, B, and UV channels independently for a custom look
• 🌅 Sunrise & sunset — smooth gradient ramps (selectable 0–2h) mimic a natural day; up to 8 timing segments
• 🔄 360° rotating panel — spin the light to aim it exactly where your plants are
• 📐 Tilt & height adjustable — shade tilts ±15° and the panel slides up/down the arm to tune intensity
• 🗜️ Adjustable clip mount — fits tank walls/rims from 1–9mm thick
• ⚡ Bright & efficient — 1500–2100lm depending on model, flicker-free for clean viewing and photos

⚠️ Fit check: The clip mount is built for glass/rims up to 9mm thick. For rimless tanks or thicker braces where the clamp won't sit, a freestanding stainless-steel stand is available (fits S300Pro & S400Pro).

💡 Pro tip: UV really shows on red and purple stems — bump the UV channel up a notch to make Rotala, Ludwigia, and AR "pop." Raise the panel on its arm for low-light plants, lower it (and add CO₂) to push growth and colour.

Choose Your Model

All three models are RGB+UV, app-controlled, and run on a 36V 1A adapter with a 100mm-wide × 18mm-thick body. Match the lamp length to your tank:

Your Top 5 Questions — Answered

1. Which model fits my tank?

= Match the lamp body length to your tank: S300Pro (310mm) suits tanks around 30–35cm, S400Pro (410mm) fits 40–45cm, and S450Pro (460mm) fits 45–50cm.

2. Does it have app control?

= Yes — every S Series model is RGB+UV and connects over Bluetooth to the WEEK AQUA app. You get 6 recommended modes, stepless R/G/B/UV dimming, sunrise/sunset with selectable ramp times, and up to 8 timing segments. (All models are 36V, so there's no remote-only version to worry about.)

3. How does it mount, and will the clip fit my tank?

= It clips on with an adjustable arm that fits tank walls or rims up to 9mm thick. The panel rotates a full 360° and the shade tilts ±15°, so you can aim the light exactly where your plants are and slide it up or down the arm to tune intensity. For rimless tanks, a freestanding stainless-steel stand is available (S300Pro / S400Pro).

4. What does the UV actually do?

= The UVA (~400nm) deepens plant colour and contrast — especially reds and purples — on top of what RGB already does for growth and colour rendering. It's what makes stems like Rotala and Ludwigia look more vivid than they do under a standard light.

5. Is it bright enough for my plants?

= With 1500–2100lm of full-spectrum RGB+UV, it suits low- to medium-light planted tanks in the 30–50cm range. For more demanding plants and richer colour, lower the panel on its arm, push the intensity, and pair it with CO₂ and regular dosing.
