New article!
The glow of a coral under reef light — brilliant green, deep red, electric cyan — looks like magic. It isn't, and the spectrum you light your tank with decides how much of it you actually see.
Our new article explains, in plain language, what fluorescence really is, why different colors need different light, and why the popular "blue light makes corals glow" only tells half the story. No biology background required.
From there it gets practical: why a broad, blue-rich spectrum from violet through red drives growth and brings out the full palette — and how Mitras LX8 and Lightbar 3 deliver it, with GHL Connect and the Control Center keeping it manageable. Presets deliver good results out of the box; fine-tuning is there when you want it.
And a look ahead: GHL Connect AI (Q4 2026) will let you match a reference spectrum at a click.
