Coralux is specialised in producing quality marine use metal halide bulb that brings out the true colours of your coral reefs and “at affordable price.”

DeepBlue comments: Coralux metal halide bulb gives the highest lux and par rating over most metal halide brand with in its price range. Its output reduction is a lot slower than many other brands. (Not like other budget brands in the market claiming to last 5000-6000hours but output goes down to 50% after a few hundred hours of use) The kelvin (colour) of the bulb stays the same all through its useful life, unlike some that start off being blue and slowly becomes yellow.

The kelvin range on the Coralux bulbs are slightly different, for example if you are looking for a white bulb go for a 14000k, if you are looking for a light blue bulb go for a 20000k.

We offer a wide range of Kelvin 6000k, 10000k, 14000k, 20000k If you aren't sure of what to use please email us.
