Most Multi-Vapor lamps are
available from 175W to 1000W. Rated life is from 6,000 to 20,000 hours, depending on model and
burning position. See Table 1.

European Metal Halide Lamps
Kolorarc, Arcstream and Sportlight are general groupings of metal halide lamps designed in
Europe (excepting MXR) and suitable for normal European control gear. These lamps do not use a
starting electrode but are started by an ignitor (explained in the Lucalox section).
Kolorarc
Kolorarc lamps are rated at 400W and have tubular, clear elliptical and phosphor coated
bulbs. The burning positions are restricted and this should be checked with each order. Lamp life
varies from 10,000 hours to 14,000 hours.
Kolorarc lamps have CCTs ranging
from 4000 to 6000K and the colour rendering Ra from 65 to 90. All lamps have KRC as the description
prefix.
