For the more aggressive environment, the cast aluminium enclosures from the deegee beacon range are perfect.
Heavy weight EPC castings, powder-coated white, are available in several sizes: the Q which has a 91 x 95mm foot-print, the M which has a 140 x 150mm foot-print, and the J, which has a 255 x 265mm foot-print. Each has four external fixing holes to secure the beacon to a bulkhead, steelwork or machinery, for example. The full range of colours of polycarbonate lens (red, amber, green, blue, clear) are available for these bases, and all the products are rated to IEC Protection Class IP65.
The J housing is a popular choice for many of the ICAO compliant LED aviation obstruction warning beacons supplied by deegee, known as the SBJ/LED. This product conforms to the Type A 10cd requirement, for low intensity aircraft warning.
All of the cast aluminium enclosures can take LED-based circuits. In addition the M and the J can take rotating mirror, xenon strobe, and filament lamp technology, suiting all warning requirements and costs.
