Approximate Initial Lumens
The value shown is based on spherical photometry, at rated voltage, of lamps that have been
seasoned for approximately 15% (or a minimum of 2 hours) or more of their rated average life.
Approximate Colour Temperature
The radiation within the visible spectrum from tungsten filament lamps is similar in spectral
distribution to that from a “blackbody” at specific colour temperatures. The Colour Temperatures
shown are approximate initial values in Kelvin (K) for lamps operated at rated voltage.
As the spectral distribution of MARC lamps does not conform to that of a “blackbody”, the values
shown are ‘correlated’ colour temperatures expressed in Kelvin.
