LED Luminaires CLEAN Surface Mounted (Ceiling) with Square Edges

Modern, economical, indoor LED luminaires.

Description of Luminaires:

  • LED luminaires for cleanrooms boast an elaborate design and state-of-the-art technologies.
  • These luminaires are designed for mounting on the ceiling.
  • The body of the luminaire is made of 0,5 mm thick steel sheet. It is provided with a white powder coat finish resistant to cleaning agents and disinfectants.
  • LED light fittings are equipped with a state-of-the-art light source - light emitting diodes called called LED.
  • These are the main advantages of LED: long operating life (50.000 hours – LED life is rated where it has reached 30% lumen depreciation), high efficiency, and the fact that their lifetime is not affected by frequent switching. LED lights are mercury-free which makes them environment friendly.
  • ELKOVO 萫pel韐 uses high quality LED chips with efficiency more than 100 lm/W.
  • RAL 9003 is used by default. Other RAL colours such as RAL 9010 or RAL 9006 are available upon request.
  • Bayonet joints and an aluminium frame are used to fix an optical cover made of toughened safety glass to the luminaire. The cover is also fixed with safety steel wires that prevent it from falling down while the light sources are being replaced. A screwdriver is needed for opening the luminaire.
  • Types of covers: Matt hardened safety glass - controlled luminance L<1000 cd/ mcan be reached at an emission angle above 60°. Therefore, these luminaires are also suitable for workstations with monitors and laser.
  • Opal cover are a cheaper version of the luminaire.
  • The plain side of the structured cover is turned outwards for easier cleaning.

Colour rendering index (Ra):

  • The standard requires the following values: Ra>80 for laboratories.
  • The standard requires the following values: Ra>90. for surgeries and operating theatres.
  • The desired index needs to be specified in the purchase order.

Chromaticity temperature (“colour of the light“):

  • For fluorescent luminaires, the chromaticity temperature can be chosen by selecting the fluorescent tube used. The „colour of the light“ can be chosen for LED luminaires as well, but this has to be done in the purchase order!

830 - warm white (approx. 3000K, similar to bulb light)
840 - white (approx. 4000K)
865 - cold white (approx. 6500K, bluish)

Electro- equipage:

  • The luminaires are produced for the nominal voltage of 230V/50Hz.
  • Light source: LED
  • The light fittings are equipped with screwless terminal boards for connection of supply conductors with solid core up to S=2,5mm2.
  • Cover protection rating (coverage protection): IP54 and IP65 - wiew of protection
  • „Declaration of Conformity” has been issued in respect of all luminaires within the meaning of the provisions of Section 13(5) of Act 22/97 Coll., as amended.

Design upon request:


The design determines these luminaires for installation in cleanrooms (operating theatres, intensive care units, pharmaceutical plants) – i.e. for rooms with high safety requirements such as pharmaceutical companies, hospitals, producers of electronic components etc.


Luminaire with matt safety glass are also suitable for workstations with lasers.
