How to Choose the Right Week Aqua Light Series (L, M, P, V, A, or Z)?

Lighting is what brings an aquarium to life. It's the difference between dull, faded greens and a lush aquascape that glows like an underwater garden. Too little and plants starve; too much and algae take over. That's why serious aquascapers often turn to Week Aqua, a lighting brand known for precise PAR output, color accuracy, and long-lasting LED performance.

With so many options like L, M, P, V, A, and Z Series, it can be hard to know which one fits your setup best. Each series serves a different kind of aquarist. Some are designed for high-tech planted tanks with pressurized CO₂, while others are perfect for low-maintenance home setups. 

In this guide, we'll help you understand how each Week Aqua light fits into your journey so you can confidently pick the perfect light for your tank.

Why Are Week Aqua Lights So Popular Among Aquascapers?

Week Aqua lights stand out because they're built for plant growth first, not just brightness.

Many budget LEDs illuminate a tank; Week Aqua designs its fixtures around how aquatic plants actually use light.

Here's what sets them apart:

• Balanced light spectrum: Every model provides the right blend of red, green, and blue light, and sometimes UV light, ensuring plants can photosynthesize effectively.

• Accurate color rendering (high CRI): Your greens look vivid, and your reds truly pop.

• Efficient heat control: The aluminum body keeps the fixture cool, protecting both the LEDs and your tank's temperature.

• Long lifespan: Each light is rated for more than 50,000 hours of reliable use.

• Innovative control options: Selected models come with Bluetooth connectivity for easy scheduling and brightness adjustment.

So rather than just adding light, you're adding precision, the kind that helps plants grow strong, fish appear more colorful, and the overall aquascape looks balanced.

How Do I Match a Week Aqua Light to My Tank Size and Type?

Before choosing a model, consider three things:

• Tank size and depth – Deeper tanks need higher PAR values.

• Plant type – High-demand species such as Rotala or Monte Carlo require stronger lighting.

• CO₂ setup – More light usually means plants need more CO₂ to stay balanced.

Below is a simple reference chart showing which Week Aqua series fits which kind of aquarium:

This quick match alone covers 90 % of planted-tank needs.

How Does Each Series Compare in Power and Features?

Each Week, Aqua line serves a specific purpose. Let's break them down one by one.

1. L Series PRO-D — The Professional Powerhouse

If your tank is large and densely planted, the Week Aqua L Series PRO-D is the workhorse you need. This light is designed for advanced aquascapes that rely on strong CO₂ injection and high nutrient levels.

Why serious hobbyists love it:

• Delivers strong PAR levels for deep tanks (over 75 gallons).

• Uses an RGB+UV spectrum that brings out vivid reds and bright greens.

• Maintains a high CRI score (95+) for natural color accuracy.

• Runs calmly and quietly, thanks to its aluminum housing.

The L Series is ideal for tanks that offer lush carpets, vibrant color contrast, and precise control over light intensity. It's often the go-to choice for competitive aquascapers who need both beauty and performance.

2. M Series RGB-UV 3.0 — Balanced Light for Everyday Aquascapes

The Week Aqua M Series RGB-UV 3.0 offers a sweet spot between power and control. It's strong enough for advanced planted tanks yet gentle enough for home hobbyists who want flexibility.

3. P Series — Balanced Brightness for Beautiful Displays

If you enjoy aquascaping for its beauty as much as its biology, the Week Aqua P Series might be your match. This model focuses on both appearance and plant health, it's great for mixed aquariums where you want to showcase fish, hardscape, and plants together.

Here's what makes the P Series appealing:

• Balanced white + RGB spectrum for vibrant, natural colors.

• Sleek aluminum design with optional shades to reduce glare.

• Energy-efficient lighting that supports most mid-light plants.

It's perfect for community tanks (40–70 gallons) where you want healthy growth and visual warmth. Many aquascapers choose the P Series when they want one fixture that does everything well: growth, display, and atmosphere.

4. V Series SE-S — Compact Efficiency for Smaller Tanks

The Week Aqua V Series SE-S proves that small tanks deserve great lighting, too. Its slim design and gentle output make it perfect for nano and shrimp tanks, where balance is more important than brute force.

What makes it stand out:

• Compact and lightweight with minimal heat generation.

• Full-spectrum output that enhances shrimp coloration and moss growth.

• Ideal for aquariums between 30 and 60 gallons.

If you're running a smaller aquascape, the V Series gives you that professional look without overwhelming the setup. It's energy-efficient, durable, and great for low to medium-light plants.

6. Z Series Z400D PRO — Smart Lighting for Nano Tanks

If you're running a small cube or desk aquarium, the Week Aqua Z Series Z400D PRO is built for you. It combines innovative technology with powerful light output in a tiny frame.

Key advantages:

• Built-in Bluetooth, no external module required.

• Dual-chip RGB spectrum for sharp, vivid visuals.

• Perfect for nano tanks up to 30 gallons.

The Z Series is loved by aquascapers who want maximum control in minimum space. You can adjust brightness, set sunrise or sunset modes, and maintain plant health without overheating or glare.

Which Series Offers the Best Spectrum for Plant Growth?

All Week, Aqua lights are engineered around natural photosynthesis curves, but their focus differs slightly.

In simple terms:

• For intense plant coloration: L or M Series.

• For balanced visuals: P or V Series.

• For easy maintenance: A or Z Series.

How Can You Match Light Intensity With CO₂ Balance?

Light drives photosynthesis, and photosynthesis needs CO₂. If lighting is intense but CO₂ levels are low, algae usually appear.

Here's a simple way to think about it:

• High-intensity lights (L & M Series): Work best with 20–40 ppm CO₂.

• Mid-range lights (P & V Series): Can run fine with liquid carbon or passive diffusion.

• Low-intensity lights (A & Z Series): Work well even without pressurized CO₂.

To maintain balance:

• Run your lights 10–12 hours per day.

• Turn on the CO₂ an hour before the lights, and turn it off an hour before they go dark.

• Watch for signs of imbalance, such as algae or slow growth, then adjust the timing or intensity.

Bluetooth-enabled models make this easier; you can automate brightness and timing so your plants get consistent light without stress.

Which Week Aqua Lights Offer the Longest Lifespan and Efficiency?

All Week, Aqua lights share the same DNA of durability and efficiency. Their aluminum housings prevent overheating, and the LEDs are rated for 50,000+ hours of operation. That's about 10 years of average use.

If energy efficiency is a priority:

• A, V, and Z Series consume the least power while maintaining consistent output.

• M and P Series balance energy use with performance.

• L Series draws more power but delivers unmatched brightness for large tanks.

This balance ensures you can find an option that suits your setup without driving up electricity costs or needing frequent replacements.

How Do You Know Which Series Fits Your Style?

If you're still unsure, here's a quick way to decide:

• Go with the L Series if you're running a high-tech, CO₂-injected tank and want complete control.

• Choose the M Series if you're after a versatile, app-controlled fixture that can grow with you.

• Pick the P Series if your goal is beauty and balance in a mid-sized tank.

• Try the V Series for smaller or shrimp-focused aquascapes.

• Start with the A Series if you're new and want something reliable yet straightforward.

• Opt for the Z Series if you love compact, smart setups with easy mobile control.

Each one has its own personality, so it's less about "best or worst" and more about fit.

Can I Control Week Aqua Lights With My Phone?

Yes, most modern models integrate Bluetooth.

• L and M Series: Compatible with Week Aqua Bluetooth Module 3.0 for app-based dimming.

• Z Series Z400D PRO: Bluetooth built-in.

• P and A Series: Manual or timer control (no app required).

With the app, you can:

• Adjust intensity throughout the day.

• Create sunrise/sunset effects.

• Sync CO₂ schedules for optimal plant response.

What's the Best Long-Term Investment for a Planted Aquarium?

If you plan to keep aquascaping for years, investing in a light that can adapt with you is key. The L Series PRO-D and M Series RGB-UV 3.0 are the most future-proof choices. Both support app-based updates and dimming control, and both can power demanding setups.

Even if you start with the M Series, it'll grow with your skills, whether you upgrade to CO₂, try red plants, or move to a larger tank later. That's the beauty of Week Aqua's modular design: once you understand your tank's rhythm, your light can follow along rather than limit you.
