Lighting : LIGHTING-June-July-2017
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. 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.
