Lighting : LIGHTING-June-July-2017
20 LIGHTING MAGAZINE | June/July 2017 June/July 2017 | LIGHTING MAGAZINE 21 exciting. “We designed one of our flood light products, the Sylvania Briteline Raptor, for sports fields, but it has gone way beyond that scope, spinning off into car parks, pathways, airports, transport hubs and container terminals,” explains Bell, who says that one of Gerard Lighting’s most interesting luminaires has a function that goes way beyond lighting. “In 2014, we took a product called GeoLED (a street-based luminaire with a 25 watt LED module), changed the optics and visor configuration and turned it into a product that was rated for Type 1 and Type 2 hazardous areas like mines. The interesting thing about this product is that it’s now being used for amenity lighting at docks and terminal ports because its green acrylic visor stops turtles swimming into the port. Turtles are attracted by the blue spectrum within a novel LED light, so having the green visor over the top is helping to protect wildlife. We are beginning to realise there are so many funky little things we can incorporate into our designs to add value.” “Dark warehouses” and “dark factories”, places that are devoid of people but filled to the gills with the whir of never-tiring robots, is an intriguing fringe trend that has quietly begun a march across Europe and the US and will no doubt reach our shores before too long. This type of facility immediately begs the question: “If you only have robots working the floor, where is the need for light?” “I would imagine in a warehouse full of robotics, maintenance is absolutely critical so good lighting is still essential,” says Ghezzi. “And these sites will still have extensive requirements for emergency lighting,” continues Portelli. “Regardless of whether the site is manned or unmanned, if the power goes out or C3PO ‘drops a chip’, emergency lighting will need to be maintained for a period of anywhere up to two hours, depending on the standard, and this brings things like backup systems into play as well.” One of the perennial lighting conundrums in warehouses regards how best to light a tall building with narrow aisles. From his experience, Shore says linear high bays have become the preferred solution. Linear high bays provide a light distribution perfect for long, narrow aisles where the fitting can be suspended at a suitable height to provide the required level of illumination. With a bewildering array of products flooding the market, Diaz says consumers need to be very careful to make sure they are buying both quality and after-sales service. “I have been brought in to fix quite a few situations where a client has cut corners and bought low cost LED products that have seriously underperformed.” But, he says, as a general rule clients are becoming more and more savvy about the possibilities afforded by new technologies and the issues associated with them. “Glare control is an interesting issue that is becoming more and more of a consideration,” Diaz continues. “The old, traditional high bays were fairly well glare-controlled but what we’re seeing, particularly with low-cost luminaires – or what I call UFOs glare bombs – is that they can be quite glary. This is a major safety issue in a warehouse situation where you’ve got forklift drivers who look up as they place palettes in the racking.” So, what recommendations does Diaz have in terms of glare control? “Do a trial, don’t just jump in the deep end. Put a fitting up, get some feedback and chose a product that’s got lensing or shielding. There’s a glare rating on luminaires so you can do your homework.” A wide range of environmental factors go hand in hand with industrial lighting. For example, in mining there is the need for explosion-proof lighting, in airports there may be significant vibration issues and many factories and warehouses require lighting solutions for sub-zero temperatures. But a big challenge that Diaz is seeing in Australian warehouses regards heat. “Where I am seeing welcome improvements in LEDs are products that can run warmer for longer without actually doing damage to the product. Recent events in Australia have shown that LEDs need to run at least at 65 degrees. In Sydney’s February 2017 heatwave, I saw high bays in industrial facilities literally cooked because they have been running too hot. I was on one small warehouse site and in the space of two days every budget LED had failed,” he continues. Thorlux installed a 130w Solow XLED with integral SMART control for daylight harvesting and PIR at a Northern Beaches Council workshop in Sydney, replacing T8 fluorescent battens. The council decided to switch to a smart system after they analysed usage patterns and found that the lights were often on during the day when no one was in the facility. With the rate of change unlikely to slow down, it is an exciting time to work in the sector, but companies need to stay on their toes. Says Shore: “We have gone from an industry that was used to significant changes occurring probably every five years to a situation where the technology is changing every three months and in quite unbelievable ways. There are examples of bioluminescence being tested overseas, where you can incorporate lighting into a tree’s biology so these developments, in concert with the development of smart control systems, mean that in terms of where the future goes, taking a leadership position in the market is up for grabs!” Super Indy Situ Warehouse Traditional fitting NSW.
