New to Aerco Dialight Obstruction Light and Beacons.
Medium Intensity Red Beacon (2000cd)
Dialight’s new D164 red beacon is the industry’s first and only LED-based medium intensity red beacon certified by ETL to be compliant with FAA standards. It easily interfaces into existing systems and can be provided as a red lighting fixture for new installations. Designed to flash or steady burn, the beacon is used to mark tall obstacles that may prove hazardous to aircraft navigation. It is designed to replace incandescent fixtures and offers the benefit of increased durability, thus reducing maintenance and replacement costs. It consumes around 1/10th of the power of incandescent fixtures and neither emits, nor is affected by, EMI/RFI interference.
Low Intensity Obstruction Lights (32cd)
The 860 series red LED obstruction light is the first LED based L-810 obstruction light certified by ETL to be compliant with FAA standards. Like the D164, it is designed for steady burn or flashing to mark any potentially hazardous obstacle. These versatile lights are available in single or double configuration in a range of voltages to meet most obstruction lighting applications.
Low Intensity Class 1 Div 2 Obstruction Lights (32cd)
This product is certified to meet both the rigorous FAA requirements for red LED obstruction lights and Class 1 Div 2 for hazardous area lighting locations. It is available in 120 or 220 volt versions and can be ordered as single or dual units.
Coloured Obstruction Lights
The Dialight 860 Series Multi-Purpose LED Light fulfills the needs of engineers and architects requiring a rugged, weather-proof fixture in color alternatives to the standard red obstruction lights. Available in green, yellow, blue and white, these fixtures are equally at home in an office building, on the Arctic Tundra, or a sailboat. Truly the LED solution to your lighting challenges.

The Geeks at Aerco are happy! At last a great alternative to Piezo Switches have been manufactured by ITW badged as ACTIVE METAL. These are ‘intelligent switches’ and the basic principle is that a material capable of supporting shear and torsional waves at ultrasonic frequencies can have those waves trapped or localized by contouring its surface. These trapped energy regions are set into motion with transducers and act as high quality resonators.
This will operate through a panel thickness of + 0.5″ and can be used through Aluminium, Stainless Steel, Plastic, Glass, are self diagnosing, self adapting, error reporting. These can bet set to be pressure sensitive, momentary, latching, timed, slide action activated.
Due to the switch being completely sealed, with no moving parts the life cycles are virtually unlimited. So far this has been tested to 100+ million cycles.
Has anyone any suggestions (however crazy) for applications?

 Over the last few years Tom Kelly has opened his home at Christmas time to the people of Liverpool. Throughout the years he has carefully planned and engineered a Christmas tree that would wow the people of his unique hometown.
Last year Tom needed snow to blow air up the hollow tree trunk in the centre of the 9ft diameter rotating display. The air activated the snow when the children recited a poem! Nothing could be easier you may think but getting the right speed of the snowfall proved to be a challenge. Tom was in need of the right sized fan for the snow activation, and one that would not overheat and most important silent operation. In consultation with Aerco’s fan product manager, a medium sized dc fan proved to solve the problem. So despite the weather outside, it definitely snowed inside Tom’s home last year.
So when it came to a major redesign for this years tree – changing from filaments lamps to a total LED display. Tom called Aerco to help with the project. In being with Liverpool’s “European Capital of Culture” year a special effort was required.
The task was to use small fans to dissipate warm air to enable reflective discs to rotate. The reflective discs would then beam rays of coloured light around the nativity scene and illuminating the rotating tree. Addas small dc fans 50x50x10mm were used for this project. Christmas 2008 will be a place of colour and wonder at Tom Kelly’s home.
You may find yourself wondering as to why Tom would give up his time and energy just for a Christmas tree. The reason, the memory of Roy Castle standing on the platform at Lime Street Station. He had just returned from his final tour of the UK. Roy knew he was dying but continued onto his final destination – Liverpool. Later he died of lung cancer. He had never smoked during his entire life. The cause, passive smoke from the theatres and clubs he had preformed in.
Thoracic surgeon, Professor Ray Donnelly founded the Roy Castle Lung Cancer Research Centre. It opened in Liverpool in 1990. The research centre is the only one of its type dedicated to defeating lung cancer.
