REEFTEK offers 250W metal halide bulbs in both 10,000K and 14,000K colour temperatures for aquarium use. While specific reviews of the REEFTEK brand were limited in the search results, metal halide lighting in general is known for certain characteristics in an aquarium setting:
-
Shimmer Effect: Metal halides are praised for creating a strong "ripple" or shimmer effect in the water, replicating natural sunlight.
-
Deep Penetration: The powerful output from a 250W bulb can reach the deepest sections of an aquarium, benefiting all corals and plants.
-
Spectrum: Different Kelvin ratings offer different aesthetic and biological benefits. 10,000K provides a bright white "daylight" look, while 14,000K has a bluer hue, often supplemented with actinic (blue) T5 lighting to balance the spectrum in a reef tank.
-
Lifespan: Metal halide bulbs have a general lifespan of anywhere from 6,000 to 20,000 hours, though performance in aquariums often dictates replacement around 6,000 hours as the spectrum shifts over time.
