Spotlight on Rotating Beacons

Rotating Beacons – 30 years and still going strong! 
It’s been over 30 years since Moflash introduced its first AC rotating beacon and they are as popular today as they were when Slade were cracking the charts here in the uk – funnily enough, another massive success from the Midlands! 

Even so, with the longevity of rotating beacons and the obvious liking for them by the customer base, they have received bad press from certain quarters of our industry. But guess what – only from companies that don’t make them! They are still one of the most effective beacons on the market and for certain applications, they cannot be bettered for performance.
One of the main arguments against the rotating beacon was the drive system – in most cases, a belt drive or worm drive operation. The point being, the belt would break. Two issues on this score, firstly the belt would have to be run continually for years before the belt broke and we fit two anyway. Secondly, it would still outlast the other beacon products with the exception of LEDs, with the only failure being the filament bulb in the unit which would need to be replaced every 1000-1500 hrs.
Another issue, as mentioned above, is the fact the lamp has to be changed. Again, in a world that needs to reduce its waste, it may be better to replace a lamp instead of the whole product, which will happen when using low cost xenons for example. And of course, Moflash have now given the customer the LED versions which effectively reduce waste and maintenance even further.     
Granted, with the world looking at its energy consumption, rotating beacons have had to evolve and Moflash have done this with the LED201/LED200 and LED401/400 series which incorporate a rotating mode. Even so, the traditional version still has life left in it – from the automotive version you see on motorways and roads around the country, to industrial applications such as steel mills, ports, airports and factories The rotating beacon has been safe-guarding personnel and equipment for years.
So how does a rotating beacon work:  
A parabolic reflector, driven by an electric motor, revolves around a continuously illuminated bulb on the vertical axis of the beacon creating a powerful beam of light travelling through 360 degrees. These units are available with either a filament or a tungsten halogen bulb. In general this type of beacon has a greater degree of light output than other models but this is reduced as the parabolic reflector only illuminates one given point at a time.
The bottom line is that rotating beacons are not the answer to all signalling applications but they are still a popular signal both on performance and cost. Moflash believe in offering its customers the widest options for signalling needs possible and by continuing to produce the R201/200, R401/400 and RA ranges, we feel we are doing this.
