Asta 20 LED Planted Aquarium Light – 4-Channel Full Spectrum Clip-On Tank Light with Remote Control | For 5 Gallon Freshwater Tanks

Give your aquatic plants and fish the light they need to truly thrive with the Asta 20 LED Planted Aquarium Light. Designed specifically for freshwater planted tanks, this powerful clip-on light delivers full-spectrum illumination across 4 independently controllable channels — giving you precise control over the light intensity and color mix to perfectly match the needs of your plants, fish, and shrimp.

💡 4-Channel Independent Brightness Control

What sets the Asta 20 apart from basic aquarium lights is its 4 independently dimmable LED channels, each targeting a different part of the light spectrum. You can adjust each channel separately to dial in the exact light recipe your plants need — whether you're growing high-light demanding plants or low-light species:

• CH1: 4 x White LEDs — primary illumination
• CH2: 4 x White LEDs — supplemental brightness
• CH3: 3 x White LEDs + 1 x Blue LED — cool daylight simulation
• CH4: Blue + Green + Red + UV LEDs — full-spectrum plant growth boost

🌟 Full Spectrum Light with CRI >90

The Asta 20 features a full spectrum design (RGBW + UV) with a Color Rendering Index (CRI) greater than 90Ra — meaning the light it produces is very close to natural sunlight in quality. This has two major benefits: your plants photosynthesize more efficiently, and your fish, shrimp, and corals display their true, vibrant colors rather than appearing washed out under poor-quality lighting. Color temperature ranges from 6500K to 8000K for a bright, natural daylight effect.

🔧 Flexible Control — Remote or Smart App

The Asta 20 offers multiple ways to control your lighting:

• Included Remote Control — adjust dimming for each channel individually, set cycle timers, and toggle on/off from across the room
• Manual Button Controller — included for quick, hands-on adjustments directly on the light
• Optional WiFi Smart Controller (sold separately) — unlocks 6 programmable timers, voice control, long-distance app control, and the ability to manage multiple lights simultaneously from your smartphone

🔊 Whisper-Quiet Cooling System

Running a light continuously can generate heat that shortens LED lifespan — but the Asta 20 addresses this with a cold-forged aluminum heat sink combined with a smart cooling fan. The system keeps the operating temperature at just 30°C and runs at under 28dB — quieter than a whisper — so it won't disturb your fish or your household during long operating hours.

🦞 360° Adjustable Gooseneck Clip Mount

The light attaches to your tank via a 360° adjustable rustproof gooseneck that lets you position the light at any angle for optimal coverage. The clamp is compatible with tank glass up to 0.95" thick, and the plastic-tipped screws won't scratch your glass. The 15.75" (40cm) gooseneck gives you plenty of reach to position the light exactly where you need it.
