Cleo HPA 2000 S High-pressure 2000 W UV-A lamp for reprography and exposure units

Product description

The CLEO HPA 2000 S is a high-pressure industrial UV-A lamp rated at 2000 W, primarily used in the reprographic and printing industries. It is designed for professional exposure units, copying frames, reproduction cameras and equipment used in the production of printing forms.

Its approximate spectral range of 250 to 480 nm, with a peak at around 375 nm, is suitable for activating photosensitive coatings. The lamp can be used for exposing offset printing plates, screen-printing stencils, photopolymer materials, technical films and other materials sensitive to UV-A radiation.

The F-spectrum version provides a high proportion of long-wave UV-A radiation. Its ozone-free quartz bulb limits the formation of ozone during operation. The gold-coated ends reflect thermal radiation back into the bulb, helping the lamp reach the correct operating temperature quickly and maintain stable spectral performance.

The lamp is equipped with flexible cable leads and does not use a conventional screw or pin base. It is not intended for direct connection to the mains supply. It may only be operated in a compatible exposure unit with the correct ballast, high-voltage ignition circuit and cooling system.

Requirements for operation

The lamp is supplied as a separate replacement UV source. A compatible industrial exposure unit designed for a 2000 W high-pressure lamp is required for operation.

The equipment must include a suitable ballast, an ignition circuit providing the required ignition voltage, heat-resistant terminals, correctly rated wiring and an effective cooling system.

Selecting a replacement lamp based only on its 2000 W power rating is not sufficient. The operating voltage, ignition voltage, spectral output, overall dimensions, arc length, cable length and cable termination must also correspond to the requirements of the exposure unit.

Safety warning

During operation, the lamp produces extremely intense UV radiation and high temperatures and operates under high internal pressure. It may only be used inside enclosed professional equipment with effective cooling and suitable protective covers. Direct exposure to UV radiation can cause serious injury to the eyes and skin. Never operate the lamp outside the equipment for which it is intended.
