Just thought I would give you an insight to the MH bulbs I use.
I find these BLV bulbs great check them out Better than most of the other bulbs I have tried IMO.
This medium-sized enterprise is a wholly owned subsidiary of the Japanese group USHIO Inc., Tokyo.
The company's view.
10000 Kelvin
The metal halide lamp with 10000 Kelvin (cool-white) was designed specially for acquaria. Because of a patented construction the colour of 10000 Kelvin remains constant throughout the whole lifetime. In deep-sea aquaria light conditions can be simulated equal to those found more than 5 meters below the surface of the sea. As most of the red light gets filtered out you receive a very natural impression of the underwater world, even with a low depth of the aquarium. The smaller portion of green light reduces the growth of algae. Corals for instance need blue light not only to maintain their colour but it is partly vital to their existence. 10000 Kelvin cool-white can turn a swimming pool into a dream of the South Sea with deep, clear sea water. Last but not least it can give the sale of seafood optical support. Fish on bluish glittering ice appears fresh and appetizing. The 10000 Kelvin cool-white can be obtained in the double ended version in 70, 150 and 250 Watt.
The single ended version is available in 400 and 1000 Watt.
We have a branch of BLV in the UK.
All my 42 BLV bulbs from 150w to 250w to 400w = 10000k are supplied by the UK Branch.

BLV UK Branch
BLV UK Branch was formed in 1992 to service the British market place. Aylesbury was chosen as the area most central for distribution throughout the British Isles, and with good stock levels of all lamp types it was soon apparent that the name of BLV would become synonimous with quality of service as well as quality of products. In 1996, the branch gained certification to ISO 9002 in its own right and this, in conjunction with the parent company's ISO 9001 certificate, gave it the status demanded of the industry today.
