Meridian 24 Edge Bar Bundle

The Meridian 24 paired with two Edge 24 bars, shipped as one complete assembly. Every bracket, cable, and the correctly sized power supply are included, so the whole system runs off a single outlet with nothing left to source separately.

What you notice first

Most people see it before they measure anything. The tank looks clearer, almost as if it has shifted into high definition. Coral edges become more defined, natural textures become visible, and the reef looks sharper from every viewing angle rather than only from straight on. That clarity is the whole reason the Meridian exists: the strongest growth, the strongest color, and the cleanest overall look modern lighting can offer.

What the corals do

Coral results are often dramatic. Colonies grow faster. Long-term slow growers begin putting on new tissue. Frags heal faster. Corals produce colors their keepers had never seen under previous lighting. Growers running the Meridian have reported major improvements within three months, often including completely new growth patterns and color expression.

The spectrum behind it

The Meridian delivers an extended violet range running from 400nm through 440nm, including true 440nm indigo LEDs. Those wavelengths are rarely included in aquarium lighting, and they are the ones tied to rapid tissue recovery, strong color development, and steady growth that limited-spectrum fixtures struggle to match. The scan below shows exactly where that energy sits.

What the two Edge bars add

Each Edge bar adds up to six inches of coverage. They mount on the Meridian's front and rear tracks using the included Edge Articulating Mounts, so each bar can be angled in toward the rockwork or out toward the glass rather than sitting fixed.

That puts light on corals from more than one angle, which is what the Edge bars were built to do: healthier, more evenly developed growth instead of light arriving from directly overhead only. The Ocular Holo Matrix optics focus that output rather than scattering it, with enough intensity to reach into tanks thirty inches deep or more.

Choosing your configuration

Two choices at checkout: the Meridian's LED layout, and the spectrum for the Edge bars. Both bars ship in the spectrum you pick, which makes six configurations in total. Here is what each one gives you.

Meridian LED layout · choose one

Original

20K look with all channels equal · high white-to-blue ratio

• A 20K blue look with all channels equal
• Four 440nm indigo LEDs on a dedicated control channel, double the two in the 14K layout
• A high white-to-blue ratio, built on the most popular lighting schedules Photon users created

Choose this if you want the bluer of the two looks and the full four indigo LEDs.

Also worth a look: Shallow Reef, if you want more white and separate control over warm and cool tone.

Shallow Reef

14K look with all channels equal · double the white LEDs

• A 14K look with all channels equal
• Twice the white LEDs of the Original layout, for a more natural shallow-water reef look
• 3.5K warm whites split onto their own channel, separate from the 5.5K neutral whites
• Turn the warm whites up for a warmer look, or the cool whites up for a crisp one

Choose this if you want the shallow-water look, with control over warm and cool tone.

Also worth a look: Original, if you want the bluer look and the full four indigo LEDs.

Edge bar spectrum · both bars, matched

Every Edge bar runs two independent channels, with the LED cluster below repeating along the length of the bar. Both bars in this bundle ship in the spectrum you select.

Reefer 14K

White, blue, and UV

• A balanced spectrum of white, blue, and UV
• A natural look that benefits both corals and fish
• The only one of the three Edge spectra that includes white LEDs

Choose this if you want a natural look carried out to the front and back of the tank.

Also worth a look: Royal Ice or UV/Blue Hybrid, if you want more color out at the edges.

Royal Ice

Royal blue and cool blue

• A blend of royal blue and cool blue
• Tuned for maximum fluorescence and color pop
• No white LEDs, so it adds nothing white to whatever the Meridian is doing

Choose this if fluorescence and color pop are what you are after.

Also worth a look: Reefer 14K, if you would rather keep a natural look at the edges.

UV/Blue Hybrid

Royal blue, near-UV, violet, and indigo

• A mix of royal blue, near-UV, violet, and indigo
• Chosen to enhance coral coloration and stimulate growth
• Extends the violet end of the spectrum out to the front and back of the tank
• Balances against the extra white LEDs in the Shallow Reef layout

Choose this if coloration and growth lead your priorities.

Also worth a look: Reefer 14K, if you want a more natural look at the edges.

The two choices work together. The Meridian sets the base look of the tank and the Edge bars decide what happens at the front and back of it. Pick bars that reinforce the layout you chose, or bars that lean the other way to balance it. Every channel is adjustable in the app either way.

Power, mounting, optics, and control

Built for the long term

The Meridian was designed around a commitment to parts availability and ongoing support, not a two-year product cycle. Whether this is a first reef build or a replacement for an aging fixture, it is a system meant to still be running, and still be serviceable, several tanks from now.
