Metal Halide Reef Fixture
The classic high-intensity reef lighting - still preferred by some SPS keepers for penetrating deep tanks.
Price: Premium
For: Saltwater $300-$1,500
📖 Overview
Metal halide bulbs produce intense point-source light that penetrates deep tanks better than most LEDs. Heat generation requires chillers or fans; power draw is significant. Increasingly displaced by high-PAR LEDs.
🛒 Buying Guide
Best for 24-inch-plus deep tanks with demanding SPS at bottom substrate.
