Safe floodlights!

Compact floodlights from Stahl not only feature a high power factor, but also a variety of installation options and enable very easy maintenance. Complying with ATEX, IECEx and PESO (India) standards, the explosion-proof 6121 and 6521 series units can be operated either with halogen, metal halide or high-pressure sodium vapour lamps.

Series 6121 floodlights are certified for hazardous zones 1, 21 and 2, 22 and can be used in gas group IIB and IIC atmospheres at ambient temperatures from -40 °C (optionally -60 °C) to +60 °C. They are designed for lamps with 70 W to 500 W power consumption. Thanks to their sea-water resistant aluminium enclosure they are ideally suited for marine applications. The modular construction of the floodlights allows for a separate installation of luminaire and ballast units and thus enable highly flexible placement and easy maintenance. This is especially the case for hard-to-access luminaires, where the ballast can remain more readily accessible for periodic isolation and transition resistance tests.

With a power factor of 90%, the luminaire ballast already meets energy efficiency requirements that will only come into effect in the EU from 2018. In addition to a symmetrical wide-beam light distribution (85% efficiency), the reflectors also enable narrow-beam spot lighting (87% efficiency).

Depending on their respective lighting power, Stahl offers 6521 series floodlights in three sizes with enclosures made from powder-coated sheet steel or V2A or V4A stainless steel. Size 3 lights can also be equipped with 1000 W halogen lamps. In addition to the standard wide-angle version, narrow-beam or asymmetrical reflectors are available. 6521 series floodlights achieve IP66 ingress protection and are approved for use in hazardous areas with gas atmospheres (zone 2) as well as for dust atmospheres (zones 21, 22) at environmental temperatures between -40 °C and + 40/+ 50 °C, depending on the type of lamp in the luminaire.

• Stahl products are marketed in Ireland through Douglas Control & Automation.
