The Reef Brite 48" 50/50 Lumi Lite Pro is a slim, high-power LED strip light that blends white and actinic blue diodes to enhance coral color, drive growth, and make a reef tank glow. Used as a supplement to your main light — or as a compact primary source for lower-demand setups — it's one of the easiest upgrades for a more vibrant display.
If your corals look a little flat under your main fixture, the fix is often more of the right kind of blue light. Here's what the Lumi Lite Pro does, why supplemental lighting works, and how to choose and use it.
What Is the Reef Brite Lumi Lite Pro?
The Lumi Lite Pro is a high-power LED strip light built by Reef Brite in the U.S. At under half an inch tall and about 2.4 inches wide, it packs a dense LED array into a slim aluminum housing designed to enhance color and support growth in corals, invertebrates, and fish. It's most often used to supplement a tank's primary lighting, but its output is strong enough to serve as a main light over frag tanks, refugiums, and other lower-demand or space-limited setups.
What Does “50/50” Mean?
Reef Brite strips come in a few spectrums, and 50/50 refers to the mix of diodes: roughly half white and half actinic blue. That combination is the sweet spot for most reef keepers — the white brings brightness and a natural daylight look, while the blue drives the fluorescence that makes coral pigments pop. It's an ideal balance for viewing your tank and for keeping color-sensitive corals happy.
Reef Brite also offers all-blue (actinic) and full-white versions, but the 50/50 is the most versatile single choice for a mixed reef.
Why Add a Supplemental LED Strip?
Even a good main light can leave something on the table. A supplemental strip like the Lumi Lite Pro helps in several ways:
- More color and fluorescence. Adding blue-rich light intensifies the greens, reds, and blues in coral pigments that make a reef look alive.
- Even coverage on long tanks. A single point-source fixture can leave dim ends; a full-length strip fills the gaps.
- A dedicated dawn/dusk channel. Run the blue independently to simulate sunrise and sunset before and after your main light cycle.
- A compact primary light. For frag systems, refugiums, or nano and low-demand tanks, the Lumi Lite Pro can stand on its own.
- Extra intensity for demanding corals without replacing your entire lighting setup.
Features and What's Included
| Spectrum | 50/50 — white + actinic blue LED blend |
| Length | 48" (also available 8"–72") |
| Profile | Under 0.5" tall, ~2.4" wide |
| Channels | Two independent channels |
| Dimming | 2 in-line dimmers included |
| Control (optional) | Neptune Apex (interface sold separately) or Reef Brite Bluetooth LE controller (sold separately) |
| Build | Designed and built in the U.S. |

Two channels and in-line dimmers
The two independent channels let you control the white and blue separately, and the included in-line dimmers let you tune intensity by hand — no controller required to get started.
Controller-ready when you want more
When you're ready to automate, the Lumi Lite Pro works with Neptune Apex systems (with the Reef Brite Apex LED interface) or the Reef Brite Wireless Bluetooth LE controller for iOS and Android, unlocking scheduling, ramping, and dawn/dusk effects.
Slim, durable, U.S.-built
The low-profile housing tucks neatly under a canopy or mounts cleanly on an open-top tank, and it's built to hold up to the humid environment above an aquarium for years of reliable use.
Choosing the Right Length
Match the strip to your tank's footprint. The 48" model is sized for standard 48-inch-long aquariums — think 75, 90, and many 120-gallon tanks. Because the Lumi Lite Pro comes in lengths from 8" to 72", you can dial in coverage for nano tanks up to large displays, and use the included Y connector to run multiple strips from one setup.
Tip: As a supplement, aim to cover most of the tank's length so color enhancement is even. As a primary light, choose a strip close to your full tank length for consistent output end to end.
How to Use It in Your Reef
- Supplement your main light. Mount the strip alongside or in front of your primary fixture and lean on the blue channel to boost pop.
- Build a dawn/dusk cycle. Run the blue channel for 30–60 minutes before and after your main light for a gentler transition your fish and corals will appreciate.
- Light a frag tank or refugium. The compact, high-output design works well as a standalone light over lower-demand systems.
- Ramp intensity gradually. When adding significant new light to an established tank, increase it slowly over a couple of weeks so corals can acclimate.
Great for Reef — and Freshwater Displays Too
While the 50/50 spectrum is built with reef keepers in mind, the Lumi Lite Pro is also a clean, bright option for freshwater planted displays that benefit from a crisp supplemental light. Its versatility across marine and freshwater setups makes it a flexible addition to almost any aquarium.
Reef Brite Lumi Lite Pro 50/50 — Frequently Asked Questions
What does the Reef Brite 50/50 do?
It adds a blend of white and actinic blue LED light to your aquarium, enhancing coral color and fluorescence while supporting growth. The blue especially makes coral pigments pop.
Is it a supplemental light or a main light?
Both. It's most commonly used to supplement a main fixture for more color and coverage, but it's powerful enough to serve as a primary light over frag tanks, refugiums, and lower-demand or space-limited setups.
What size tank does the 48" fit?
It's sized for standard 48-inch-long aquariums, such as many 75, 90, and 120-gallon tanks. The Lumi Lite Pro also comes in lengths from 8" to 72".
Can I dim or control it?
Yes. It includes two independent channels and two in-line dimmers out of the box, and it can be automated with a Neptune Apex (interface sold separately) or the Reef Brite Bluetooth LE controller (sold separately).
Does it work with a Neptune Apex?
Yes, with the Reef Brite Apex LED interface (sold separately), you can control the Lumi Lite Pro through your Apex system for scheduling and ramping.
Is it good for freshwater tanks?
Yes. Although the 50/50 spectrum is designed for reef tanks, it also works well as a bright supplemental light for freshwater planted displays.
