Dalua Illumagic X4 Reef LED Light
The Illumagic X4 is a flagship reef LED built for aquarists who want museum-grade color and serious coral growth without the wasted watts and heat of ordinary fixtures. Its dense-cluster LEDs fire through Illumagic's DBR (Diffusion by Refraction) silicone optics, delivering a rich, blended spectrum with zero PAR loss, and those lenses carry a lifetime warranty. The entire fixture is tuned through the Dalua Ecosystem app, so you can shape spectrum, intensity, and sunrise-to-moonlight schedules from anywhere in the world.
Chosen by World Wide Corals, Polo Reef, and reefers everywhere, the X4 runs noticeably cooler than competing lights and puts its energy into the colors corals actually use. Pair it with your corals and browse more aquarium lighting to complete the build.
Why the X4 Stands Out
- DBR silicone optics, lifetime warranty: Diffusion by Refraction lenses will not yellow or burn, so you keep full PAR for the life of the light.
- App control from anywhere: The Dalua Ecosystem app runs custom spectrum, intensity, weather effects, and 24/7 schedules over WiFi.
- Dense-cluster LEDs: 40W clusters blend a complete reef spectrum with an adjustable 14,000K to 20,000K color temperature.
- Cooler and more efficient: Runs significantly cooler than competing reef lights and skips the unusable colors that only waste watts.
- Built to last: Dual-heatsink plus fan cooling and a Meanwell power supply backed by a 2-year warranty.
Reefer Pro vs Reefer Blue: Choose Your Spectrum
| Reefer Pro | Reefer Blue | |
|---|---|---|
| Spectrum | The broadest, most complete spectrum Illumagic offers | Blue-dominant, heavier on actinic and violet |
| Look in the tank | Balanced, natural daylight through deep blue | Deep blue reef pop with strong fluorescence |
| Best for | Full-spectrum growth plus true-to-life color viewing | Maximum coral fluorescence and that classic blue reef look |
Both versions share the same fixture, optics, and app control. The difference is the LED spectrum binning, so pick the look you want over your reef.

Coverage & Mounting
Each X4 covers roughly a 23" x 23" footprint and measures 9.6" x 9.6" x 1.49". Narrow and wide lens options let you match the beam spread to your tank, and the 10 ft power cable gives plenty of reach for tank-mount brackets, mounting arms, or a hanging kit (mounting hardware sold separately).
Recommended Pairings
- Corals to grow under it
- Saltwater supplies for the rest of your reef
- More aquarium lighting to compare fixtures
Frequently Asked Questions
Should I get Reefer Pro or Reefer Blue?
Choose Reefer Pro for the broadest, most complete spectrum and the most natural color rendering, or Reefer Blue for a bluer, more actinic look that maximizes coral fluorescence. Both grow corals beautifully.
How big a tank does one X4 cover?
One fixture covers roughly a 23" x 23" footprint, so a single unit suits nano to standard reef cubes and you can run multiple units in a row over longer tanks.
Do I need a separate controller?
No. WiFi control is built in through the Dalua Ecosystem app, so you can program spectrum, intensity, and schedules right from your phone.
Is it just for reef tanks?
The X4 is tuned for reef and saltwater display, but its adjustable spectrum makes it flexible enough for planted and freshwater display tanks as well.
