UV-light! (models -12, -21, -22)
The UV-light used by ColorLight is chosen for most efficient result in marine
applications. The wavelengths are below 400 nanometers, thus not visible for the
human eye. An intensive radiation is generated from the high luminance of the
arch inside the bulb and should not be glared into from close distance.
Intentionally ColorLight is allowing a small leakage of white light making the beam
vaguely detectable in fog. Avoid quick switch on and switch off as it may shorten
the lifetime of the bulb. Allow a couple of minutes cool down period, if possible.
UV-light overheat
CL20, CL25 and CL35 searchlights are designed and built primarily for the marine
environment.
UV light generates a lot of heat and we use ambient air as a coolant for our lamp
body. For uses other than marine this must be taken into account so that sufficient
cooling is available or to adapt the operating time to prevent overheating damage
such as cracked UV glass.
Eye safe exposure time for UV
CL25-12/21, CL35-12/21: Max 2 minutes at 1 m. Max 4 minutes at 2 m. Max 9
minutes at 4 m. Max 65 minutes at 9 m.
CL25-22, CL35-22: Max 1 minute at 1 m. Max 2 minutes at 2 m. Max 4 minutes
at 4 m.
Max 30 minutes at 9 m.
Welding eye glasses are recommended if you for some reasons have to expose
your eyes longer periods at those close distances.
We see no reason for such exposure even at service activities. Sunglasses are
also good protection.
Reflectors
The parabolic reflectors developed by ColorLight have an extremely smooth
surface to focus the light in wide or narrow beam. Bare fingers should never touch
the reflector surface. If inadvertently touched, the reflector surface should
immediately be degreased with alcohol and a soft lint free cloth.
