💡 Best Aquarium Lights for Different Setups

---

🌱 Freshwater Planted Tanks

• 🔆 Spectrum: 6,500K – 7,000K (daylight full spectrum, mimics natural sunlight).
• 📊 PAR (Photosynthetically Active Radiation): 30–80 µmol/m²/s at substrate level for medium-to-high demand plants.
• ⚙️ Recommended Tech:
  • LED: Fluval Plant 3.0, NICREW SkyLED Plus, Finnex Planted+.
  • T5 HO Fluorescent: Strong, wide coverage but higher heat and bulb replacement.
• 🌿 Why: Supports photosynthesis, brings out plant colors, prevents leggy growth.

🐠 Freshwater Fish-Only Tanks (No Plants)

• 🔆 Spectrum: 6,500K – 10,000K (white to cool white).
• 📊 PAR: < 30 µmol/m²/s (no high light needed).
• ⚙️ Recommended Tech:
  • LED: NICREW ClassicLED, Aqueon OptiBright.
• 🎨 Why: Enhances fish coloration without causing algae blooms.

---

🌊 Saltwater Fish-Only Tanks

• 🔆 Spectrum: 10,000K – 20,000K (crisp white + blue).
• 📊 PAR: 50–100 µmol/m²/s.
• ⚙️ Recommended Tech:
  • LED: Current USA Orbit Marine IC, NICREW Marine LED.
• 🌊 Why: Provides natural ocean-like shimmer & supports fish coloration.

🪸 Reef Aquariums (Corals)

• 🔆 Spectrum: Blue (450–470 nm), Violet/UV (380–420 nm), with some white (10,000K–20,000K).
• 📊 PAR:
  • Soft corals/LPS: 100–200 µmol/m²/s.
  • SPS corals: 200–400 µmol/m²/s.
• ⚙️ Recommended Tech:
  • LED: Ecotech Radion XR15/30, AI Prime HD, Kessil A360.
  • Hybrid LED + T5 HO for even coverage + shimmer.
• 🧪 Why: Promotes zooxanthellae photosynthesis (coral growth and coloration).

⚡ Technical Features to Look For

• 🌓 Programmable Timers – Mimic sunrise/sunset, reduce stress.
• 🔄 Dimmable Channels – Adjust intensity for plants/corals vs fish.
• 🌊 Shimmer Effect – LEDs provide natural sunlight ripples.
• 🔋 Energy Efficiency – LEDs last 30,000–50,000 hours vs ~12 months for T5 bulbs.
• 🌡️ Heat Output – LEDs stay cool, T5 and halides require fans/cooling.

---

🚫 Avoid

• ❌ Incandescent Bulbs – Too hot, wrong spectrum.
• ❌ Cheap Household LEDs – Not full spectrum, low PAR.
