Giesemann Megachrome Marine 250W 12,500 K Mogul Base Metal Halide Lamp: MegaChrome Marine 12.5K This lamp is specifically designed for marine aquaria that demand a very high light intensity simulating natural sunlight within the first 5ft of water. Its special light spectrum has less red and more blue to enhance the brilliant and fluorescent colors of your fish and corals. Compared with similar Kelvin rated bulbs, the MegaChrome Marine lamps have a significantly higher lumen and PAR output and color stability in excess of 3000 hours.
Giesemann Megachrome Marine 250W 12,500 K Mogul Base Metal Halide Lamp: MegaChrome Coral 14.5K The perfect light source for a bluer spectrum to simulate natural daylight on the reef at depths of 5 - 20ft. The spectrum is a slightly bluer than that of the Marine but retains the high lumen output and PAR values relative to its Kelvin rating resulting in the ideal light to show up the blue and green fluorescence of your corals. The high Kelvin values offered by this lamp are made possible by a special manufacturing process which ensures that both the light intensity and the color stability remain stable over a long period.
Giesemann Megachrome Marine 250W 21,000 K Mogul Base Metal Halide Lamp: MegaChrome Coral 21K The perfect light source for a much bluer spectrum to simulate natural daylight on the reef at depths of 15 - 30ft. The spectrum is much bluer than that of the Marine for maximum colororation of corals resulting in slower growth rates but better coral coloration.
