Metal Halide Lights

Blue MH lights Has anybody tried these lights. It is a Blue MH double ended light with a 20000kelvein Temp Specturume.

Just curious?

you can use MH with any corals that are photosynthetic. whether or not they actually need that much light is another thread.

not a big fan of the 20K bulb so not any help on that question.

The reason they are blue is the 20,000k. The lower the k the witer the light to yellow around 6500k. basically the higher the k the more vibrant the color you will see (provided the water is well balnced) the lower the K the more growth you will see. there are a lot of factore that play into it though as far as color and growth. Thats just a basic difference. Also with 20k you may not need actinic suplimentation. matter of taste.

Lighting selection is one of the most frustrating things IMO.
