SPECIAL FEATURE LIGHTING that far exceed the PIR’s normal operating current and shorten the life of the switch in the PIR. Poor power factor of many LED lamps and drivers can also reduce the PIR’s life and can result in false claims of efficiency (Lumens/Watt) by manufacturers. Equally important are the LED arrays, lenses and back plate reflectors that combine to create the right light ambience; be it a focused beam, a wide field for security coverage or warmth indoors. Daylight, cool white and warm white are common options. Daylight and cool white are typically used for outdoor lighting, warm white is often preferred for just indoor use, although we also chose it for our carriage lantern style outdoor LED light fittings. Installation Being up a ladder wrestling with a heavy unit is pretty complicated in itself; but at last manufacturers seem to have followed our lead and have a heart for installers. You should be able to find luminaires that are easy to wire B.E.G. with accessible rear terminal boxes and then just ‘plug in’ the light controller. The pennies you save by choosing a substandard unit will soon be eaten up in the working time you waste. Replaceable, glands that allow for the size and shape as the wires you are using and captive screws in the terminal cover are all helping to simplify the whole process of choosing and installing LED lighting. Easy loop out to other luminaires on the same circuit provides the flexibility – and economy – to design master and slave set ups. The latest trends We all know that as new technology advances, prices come down – but who really benefits? There’s a downwards price spiral which always ends the same way with low margins all round and poor quality low end products queering the pitch for everyone. But sometimes someone decides to take a different approach and use the potential offered by new componentry to create much more value, not just a price cut. Take Timeguard’s new Nighteye Plus project which was triggered by the introduction of LEDs that don’t need drivers to smooth out the current flow. Most engineers focused only the cost implications, introducing the slimline panel shaped floodlights you’ll have seen around. They have their place, and Timeguard now has a few in its range – but then we went a step further to use the new technology to add value rather than just strip out cost. Prismatic lenses and polycarbonate recessed reflector plates have done away with the need for a clear cover to protect the unit. Tough as old boots, these units uncomplicate your choice by ticking all the boxes for looks, functionality and easy installation. Can suppliers make it less complicated? Yes and simply. Manufacturers can put all the information you need online and make it readily visible on the outside of the box, and good wholesalers can do the quality control by only stocking the products that will last and give you the opportunity to provide – and charge for – added value.
