Designed to replace 35-100W HID and 24-36W CFL fixtures, the SLBt is a great LED solution for minor roads, residential streets and other public spaces where modest levels of illumination are required. Comes with 90,000hr (L90) 5 year warranty.
Application areas: Street and residential road lighting; Pedestrian street; Car parking
Designed for side mounting on 42mm-60mm poles, or post top on 48mm-76mm posts.
The SLBt can be upgraded with a dimmable driver and minicell photocell for contrability.
Megaman are pleased to announce that they now offer serviceable LED solutions for a range of applications.
Across its LED product development in replacement lamps, modules*, light engines** or fixtures, MEGAMAN are pleased to announce that they are now able to offer user serviceable LED solutions. This decision has multiple benefits. Not only can MEGAMAN LED light sources be serviced and upgraded to the latest LED technology, but by using serviceable solutions, existing luminaires can be retained, minimising the environmental impact of progress. This approach overcomes some of the inflexibility previously experienced by end users, of completely integrated LED solutions.
MEGAMAN also recognizes that some basic light fixtures have such a low carbon footprint that engineering for replacing the LED may not always be viable and it can be greener to replace the whole fixture. MEGAMAN fixtures in this category are 100% recyclable with component parts that can easily be dismantled and separated. They are still designed with serviceability in mind so have commonly used fixings or sizes for easy replacement long into the future.
For MEGAMAN LED modules, light engines and fixtures it is recommended that the installation and servicing is performed by a qualified and competent expert.
The MEGAMAN LED product range offers the highest degree of design freedom for lighting designers, both in terms of addressing future advances in LED technology, as well as offering a wide range of colour and output choices.
* LED Module is a unit supplied as a light source. In addition to one or more LEDs it may contain further components, e.g. optical, mechanical, electrical and electronic components, but excluding the control gear.
** LED Light Engine is the combination of one electronic control gear, integrated or remote, and one or more LED modules.

Almost by definition, a warehouse is a large area. If there are people working in there (it is an if – some warehouses are fully automated) then it must be illuminated to a decent level. This means the energy consumption can end up being high, unless you do something about it.
In essence, there are two types of warehouse: those with racking and those without. This will determine the lighting layout and the controls to use. Some are large open areas where goods, often on pallets, are stored no more than, say, 1.5m high. It’s a good idea when designing the lighting to install more, lower wattage luminaires with a wide light distribution. They are installed closer together to minimise shadowing and give good vertical illumination.
The other type of warehouse, which is very common, uses racking, often to a high level, maybe 6-10m.
Our warehouse uses a combination of both. On the subject of storage areas, EN 12464 says that a continuously occupied space where little perception of detail is required should be lit to 200 lx. Manned gangways/aisles should be lit to 150 lx. The vertical illuminance on the racks should also be 200 lx.
To get the greatest benefit from a control system, you must know how the warehouse is used. How long do staff stay in certain areas? Do they cluster in one spot? How much movement is there in the aisles? If you don’t ask these questions, you won’t achieve the best result.
One of the biggest savings to be made is in unoccupied aisles. I went to a distribution centre for a major wholesaler that had literally dozens of aisles. These aisles were a good 30m long, maybe more than 40m. However, at any one time, only about a quarter of the aisles were occupied.
These guys knew their controls and had installed movement detectors at the ends and along the aisles. When the aisle was empty, the luminaires dimmed to 10 per cent. As soon as someone entered, the luminaires switched to full brightness giving 200 lux both horizontally and vertically. They had further refined the technique, and achieved greater savings, by switching on only those luminaires in the vicinity of the person picking the goods. Further down the aisle, and behind, the luminaires were dimmed.
Ex-Or’s QuickSet Pro setup device
Outside the aisles, savings can be made by zoning so that only the occupied areas are illuminated to full output. But beware, switching off totally can make a place look gloomy and desolate; it might even be a health and safety hazard. It’s much better to dim to 50 or 25 per cent.
If you have ever done a Leni calculation, you will know that it includes a figure for the quiescent power load of the sensors. This is also known as the parasitic load. The Ex-Or unit used here has a low rating of 150mW.
One final point that needs to be mentioned is ease of setup. With some other suppliers, commissioning can be a pain and may even require an outside specialist. Ex-Or has devoted a lot of effort developing its QuickSet Pro handheld setup controller.
Our warehouse is 25 x 50m and 14m to the apex. It is lit to 200 lux using three different types of luminaire.
This gives a general view of the whole warehouse fully lit. Like many warehouses, several types of luminaire are used. Above the tall aisles, the luminaires have a narrow oval shape that distributes the light along the aisles but minimises it in the other axis to avoid hot spots. These can be fitted with individual LightSpot HD sensors to track movement along the aisle. Alternatively, you can group the sensors. They can be controlled by Dali or DSI signals. At the ends, a mask can be fitted on the sensor so movement in the open area doesn’t trigger the aisle lights.
In the open area, mounted at the same height, are high bays with a symmetrical distribution. It’s worth noting that the Ex-Or sensor is available for different mounting heights from 2.5-16m.
Finally, there is a low level section which is used for heavy goods or which have hard-to-read labels.
Controls can sometimes be difficult to illustrate in a static picture. If the lights were switched off, you would see nothing. This option uses PIR controls so the luminaires only operate when people are using the aisles.
Here, the tall aisles have been switched off because no-one is using them. The low area in the foreground is at full brightness. This is switched by the standard HD sensor. This covers an area approximately 10m in diameter. Ex-Or is proud of the optics in its products and this unit will detect large movement at the edges of the area – when someone enters the space, for example – but the central area, about 7m in diameter, will detect small movements such as staff entering data into a notepad. The HD unit contains 155 detection points, three times as many as some on the market.
The foreground open area is at 100 per cent because it is still in use, but it would be worth zoning those luminaires at the edges, especially in a larger warehouse.

Energy saving Can be significant with intermittent use
This is the night shift. Only a few staff are working. There is no activity in the foreground and so the luminaires are dimmed to 10 per cent. This saves energy but also means there is some illumination for safety reasons and to give the staff a feeling of security. Elsewhere, the luminaires are off or at 10 per cent.
The luminaires are at 100 per cent all along the working aisle because the angle of the detector high up picks up all the movement. A useful feature of the LightSpot HD detector is that you can link a master detector to three bus sensors. Look for QuickLink in the literature. This means that data such as occupancy and light levels can be shared across the sensors.
Each detector has its own memory chip that contains particular settings such as illumination level, timing and switching frequency. These settings can be altered from ground level using the QuickSet Pro controller. This controller can also download the recorded data and then upload it to a computer or energy management software.

Lux talks to lighting designer Owen Xuan of Firefly Lighting Design and Ciaran Kiely of Neonlite/Megaman about the lighting concept, execution and use of all LED lamps at these two prestigious new venues.
Thanks to backing from Sheikh Mohammad, Dubai looks set to be one of the world’s first so-called ‘smart cities’, but in each location the priorities and the technologies will be different, believes Shanaah
Smart cities are happening and they will transform exterior lighting companies into flexible, high technology electronics suppliers.
That’s the view of Fadi Shanaah, general manager of Schreder’s operations in the Middle East. He believes that, like the rapid adoption of LEDs, smart cities will become a reality faster than people expect.
Shanaah: ‘There’s no doubt that smart cities are going to become a reality.’
‘How fast depends on the region. We’re lucky that the UAE has made big steps towards adopting the technology. Dubai, for instance, is moving quickly thanks to the backing of Sheikh Mohammad and there are people now who are driving it. At the moment it’s at the high-level stage and what’s missing is the detail. But in the coming months and years you’ll start to see those high-level concepts translated into useful technologies that will benefit you and me.’
He believes safety, security and connectivity are the key roles that intelligent lighting will play in smart cities.
‘It’s really exciting – but it’s challenging too. The technology has changed completely so for a lighting company that means moving from being a traditional lamps and luminaires company into become an electronics manufacturer. That means changing your R&D and even changing your people. In Schreder we’re use the phrase ‘beyond lighting’.
The Schreder Shuffle points to the future of exterior lighting, bundled full of high technology services and features
‘Look at the big players – Philips, GE and Osram – having to sell their lamps businesses, as that model is dying. They need to change and they need to change quickly because the transition to LED and electronics is happening faster than than people thought.’
Schreder will be exhibiting its first major luminaire range targeting the smart city market at LuxLive Middle East 2016 in Abu Dhabi in April. Shuffle is an ‘integrated smart city luminaire’ with features such as wi-fi, security cameras, public-address speakers, air-quality sensors and electric-car chargers.
It’s really exciting – but it’s very challenging too as it means we need to change our businesses fundamentally”
He believes the low-power wide-area standard LoRa – an open protocol currently being adopted by Cisco and IBM among others – could be a possible candidate for data transfer between street lights in a smart city. Schreder has its own Zigbee-based proprietary system, but Shanaah believes that lighting companies will have to adopt whatever technology gains currency in the smart city landscape.
‘Each city has slightly different priorites and technologies and each will move at its own pace,’ says Shanaah. ‘But there’s no doubt that smart citi
The report reveals that 56 per cent of European businesses are failing to keep their safety systems up to date following fit-outs and refurbishments.
The emergency lighting installations in half of our public buildings no longer meets the required lighting standards. That’s the conclusion of a major survey of emergency equipment installers commissioned by fire detection manufacturer Hochiki Europe.
The report reveals that 56 per cent of European businesses are failing to keep their safety systems up to date following fit-outs and refurbishments.
One of the major problems appears to arise as a consequence of internal refurbishments, when areas are reorganised to suit new requirements, but the emergency lighting is not altered to suit those changes.
Standards are clear that any change to a designated escape routes requires a similar adjustment in the lighting of that route. A new risk assessment is also essential before any installation can be deemed to be fit for purpose and that includes an assessment of any designated illumination for fire-fighting equipment stations. If equipment is shifted from one place to another, then dedicated lighting needs to follow it.
Maintenance is also singled out as an issue. The survey suggests that building owners see emergency lighting as a fit-and-forget system, with 55 per cent of the survey respondents reporting that customers seem to be more concerned with initial expenditure rather than the on-going cost of running and maintaining the system. Almost a quarter of those surveyed felt that building managers see maintenance as an unnecessary expense, with almost 75 per cent seeing system maintenance as a ‘tick box’ exercise.
The top five failings reported were:
Inadequate emergency lighting signage
Inadequate illuminance levels
Blocked emergency exits
Batteries not charged or not working
Inadequate logbook records being kept
‘Many building owners do not realise that new fire risk assessments should be carried out when a room or building has had a change of use,’ says Simon Massey of Hochiki. ‘As an industry, we need to help building owners understand such fire safety regulations.’

The scarred exterior of The Address in Dubai last week. Investigators now believe that the lighting installation was to blame for the blaze.
Lux reports: The lighting installation at The Address in Dubai is now being blamed for the spectacular New Year’s Eve fire, say the police.
A short circuit on the cabling to a projector light fitting on the14th floor has been identified as the source of the blaze at the 63-storey luxury hotel.
Fire experts say the fact that only one of the four light fittings on that projecting ledge had melted cables, coupled with witness statements, pinpoints the cause of the disaster.
The news will send shock waves though the lighting and installation industries in the region and will inevitably lead to calls for better standards of equipment, training and tighter specifications.
The pinpointing of the source of the fire to the external lighting explains the mystery of why the internal alarms – which are triggered by smoke – did not sound immediately. Hotel guests told police that they didn’t hear the alarm and only evacuated the building when they were instructed to by hotel staff.
Dubai Police chief Maj Gen Khamis Al Muzeina told the National newspaper yesterday: ‘The results of the investigation come after inspecting the area where the fire started, collecting and testing evidence as well as listening to witnesses’ testimonies.’
Dubai Police forensic scientist Ahmed Mohammed Ahmed told the press that the lighting cables run alongside cabling to other services on the ledges. He believes the fire began between apartments 1401 and 1504, in an area that contained a small, 1.1-metre-wide pathway and a ledge.
‘Experts checked apartment 1504 and came to the conclusion that the fire spread to the unit from the side of the window, which looks onto the pathway and the ledge, and not from inside the apartment,’ Mr Ahmed said.
Fifteen people were injured, while one person suffered a heart attack while being removed from the building.
How can Megaman’s latest lighting solutions; including reflectors, modules and integrated fixtures enhance your retail application?
Attracting Customers
Lighting plays a crucial role in winning a customer’s attention, and designers are increasingly using it to enhance the shoppers experience, especially in high end retail shops.
Setting the Mood
Lighting affects customers mood and energy levels. It also provides guidance and orientation. The correct lighting creates a welcoming, comfortable and enjoyable environment, lengthening customers visits and influencing their buying habits.
Enhancing Product Appearance
A quality lighting system can make a big difference in retail settings by enhancing products visual appeal in terms of colour, shape and texture. Used correctly, lighting can provoke more interest in your product displays. For example; Megaman’s Perfect White technology enhances fluorescent whitening agents, making white products stand out from the crowd.
Creating a Desirable Instore Experience
Many luxury retail stores use a combination of ambient, accent and decorative lighting to create a positive shopping experience.
Apple looks set to include a li-fi capability in future versions of the iPhone, meaning it can access high-speed data using lighting.
The backing of a tech giant like Apple would transform the technology from scientific curiousity into a mainstream technique for accessing the internet, and provide a huge boost to the lighting industry.
The iPhone’s operating system now openly references li-fi capability in its programming code.
Li-fi uses modulated visible light from LEDs to transmit data to enabled devices. It’s invisible to the human eye, and is much faster than traditional wifi.
Apple already holds a patent on using its camera to capture data as well as images, so the company is well placed to exploit the new technology.
It’s not the first time this year that Apple has been making news in the lighting industry.
Last month the company added a blue-light reduction feature into an update to its operating system in what was widely seen as the the first acknowledgement by a major manufacturer that blue light can be a health hazard.
Megaman achieved another industry first in April 2015 with the launch of a wide range of LED products that incorporate a new Dim to Warm system which provides improved dimming performance with the warmth and characteristics of halogen. These LED’s emit a warmer light when they are dimmed with a colour temperature that changes smoothly from 2800K to 1800K when dimmed from 100% to 10%
