Metal halide lamp with double arc tubes

A metal halogen lamp comprising:

• an outer casing,
• a base part,
• and inside the outer casing, first and second arc tube members, which are electrically parallel-connected and are connected via conductive members to the base part, each arc tube member having a first end, facing toward a top part of the outer casing opposite the base part, and a second end, facing toward the base part, the first arc tube member is arranged closer to the top part than the second arc tube member, and the second end of the first arc tube member and the first end of the second arc tube member adjoin an imaginary plane (P) defined substantially transversely to the center line (CL) of the outer casing, which center line extends from the top part to the base part,
• wherein the respective arc tube members are of elongated configuration, each with a defined imaginary center line (CL′, CL″),
• wherein the conductive member comprises a first conductive rod coupled to the respective first end and a second conductive rod coupled to the respective second end, and the two conductive rods extend parallel with the center line (CL) of the outer casing and are adjacent to the outer casing, and
• wherein the center lines (CL′, CL″) extend substantially parallel with each other and at an angle (α) of 40-50° to the center line (CL) of the outer casing, and the extents of the first and second arc tube member and extents of the portions of the first and second conductive rod between their coupling points with the respective arc tube members form a parallelogram.
