I'm not sure.
Originally, Nosram was an independent UK company, but was taken over by LRP in 2000.
I cant really figure out what the point is - the product seems to be the same (specs, looks), except from color (is red better than blue?
) and in some cases, the cabinet. The product line, warranty and prices also seems to be the same.
Some kind of virtual/artificial competition, making LRP not looking too monopol-like on some markets? This is just speculation, I simply dont know. Both brands are reprensented in my country, as many others
