Ningbo Royalux Lighting 11703
This outdoor wall lamp is made of graphite-grey aluminium and is equipped with a movable arm, which makes it possible to adjust the lamp head up and downwards in a flexible way. The lamp comes with high-quality LEDs that give out a bright light. The built-in motion sensor has a range of 10-metres and a detection angle of 120-degrees. In addition, the duration of the lighting period can be adjusted from five seconds to eight minutes.
Fluxwerx, Inbox
The design concept for this energy efficient recessed LED light was inspired by skylights and contemporary architecture. Available in different sizes, it delivers greater depth, definition and detail, eliminating the monotony and anonymity of large ceilings. Inbox produces a uniform light to illuminate wide areas while keeping glare to a minimum. Its precision engineered, high transmittance acrylic lenses mix and disperse light, and ensure that the LED point sources are invisible from view.
Ribag Licht Mesh
With a high degree of flexibility and innovative lighting technology, this pendant luminaire meets the needs of today’s dynamically changing working environments. Mesh is suitable for use at the workplace, in conference rooms and in reception areas, as either a pendant or a surface-mounted light. Its energy-optimised ratio of direct and indirect light, excellent glare reduction as well as the wide range of different available light colours and intensities, from 2,700 to 5,700 kelvins, makes it highly adaptable.
Astro Lighting Edge Reader
The Edge Reader elegantly combines ambient lighting, which provides a soft, soothing and uniform glow, with the directional functionality of an LED reading light. Its minimalist structure enables the light to blend into the respective room and achieves a note of architectural distinction even when it is not in use. When it finally serves as a bedside lamp at night, it stands out from the wall and almost appears to float.
Dark, Spaze
The Spaze lighting collection includes both a T5 fluorescent tube and LED spotlights. Due to its minimalist lines, the black light body blends in with large kitchens or offices, and is also suitable as a light source above retail counters or in reception areas. Spaze is available both in a ceiling mounted version and as a pendant light. All the lights can be dimmed and are controlled digitally via a DALI interface.
BÄRO Intara ID
This semi-recessed LED luminaire combines the elegance of a built-in light with the flexibility of a surface-mounted spotlight. Its patented swivel-tilt mechanism allows for a 355-degree rotation and the tilting of the light by 35-degrees. A newly developed LED technology ensures that the light reaches the target surface in a controlled manner and produces soft, defined light cones. Intara ID offers even more flexibility by providing several power ratings, interchangeable optics and a variety of LED spectrums.
Eureka Lighting Prince
Prince is a linear wall lamp featuring a precision-machined glass shade and is enclosed by a chrome frame. The powerful yet highly efficient 17-watt linear LED light is softly diffused through a thin nanostructure micro-lens, while the refractive nature of the glass results in evenly distributed illumination. Supplied with a micro junction box for discreet mounting, it features integrated hooks for easy installation.
IP44 Schmalhorst shot
This outdoor lamp made of diecast aluminium can be freely positioned anywhere on a lawn or in flowerbeds. An accompanying aluminium ring supports the light ball when it is placed on hard grounds, for example patios. Equipped with a flood reflector, shot helps to create focused light effects. Its high-quality workmanship results in a reliable, long service life and makes sure it is easy to maintain.
Zumtobel Nightsight
This series of outdoor luminaires was developed to master the challenges of contemporary urban lighting whilst fulfilling established quality criteria. Nightsight includes a range of different kinds of luminaires, which are designed to illuminate both vertical and horizontal surfaces uniformly, as well as to add specific accents. The calculated use of light and shadow, bright and dark zones, as well as different planes of light serves to set the atmosphere in public spaces.
LED Linear VESTA
Vesta is a linear LED surface mounted luminaire, which was developed for use with base units. To ensure the optimal illumination of work surfaces, the profile allows combinations of fourteen different linear LED lamps and six diffusor optics. The aluminium mounting profile is designed for angles of 30 or 60-degrees, and optionally available in black or silver.
Tobias Grau XT-S Suspension
The XT-S Suspension shows a particularly flat and elegant design of the luminaire head. This is achieved through a combination of advanced LED technology and a newly developed light panel that brings the benefit of providing optimum glare control and light distribution throughout the workplace. The light can be set to six predefined light colours, to a personalised light colour scheme, as well as to the automatic adjustment to the time of day.
David Morgan Review: EcoSense RISE
When an exterior-rated modular LED projector system with 500,000 options and a delivery lead time of no more than two weeks is launched, then I was keen to take a closer look.
The system is RISE and is the latest offering from US manufacturer EcoSense.
EcoSense is a Los Angeles-based company started in 2009 by the founders of Color Kinetics, George Mueller and Ihor Lys. They met at Carnegie Mellon University while studying for PhDs and went on to build the company into a leading player in the LED lighting market before selling to Philips in 2007. Their patent portfolio includes 50 patents covering a variety of LED technologies including Power Core, the combination of a power supply and control system for LED lighting.
The EcoSense design team has taken a radical approach to the detail design of the RISE projectors, which enables users to change the optics on site while maintaining the IP rating.
At the core of each RISE projector luminaire is a light engine comprising a single Cree high power LED driven by a digital mains voltage driver and fitted with a five-degree custom-designed lens. This light engine can be run at up to eleven watts, is sealed to an IP 68 rating and can deliver up to 700 lumens with more than 40,000 centre beam candelas.
In addition to the single module luminaire, there is a quad version with four light engines in one housing. This luminaire produces 2,800 lumens with over 168,000 centre beam candelas, which is outstanding for such a small form factor.
Unusually, the light engine is a separate module, with the driver mounted behind the LED board that is then fixed into the body casting. Transfer of heat from the aluminium LED pcb, via a separate die cast heat sink to the outer body casting, is achieved by direct metal to metal contact between the two castings. This configuration creates a very small form factor that apparently achieves such good thermal management that a maximum ambient temperature of 50-degrees celsius continuous use rating is specified.
The RISE range offers a very wide array of light distributions and these are produced by fitting a secondary optic in front of the standard five-degree lens in the light engine. These secondary optics ensure that the lit effect produced is extremely smooth, although there must be additional light losses caused by these additional lenses/diffusers. To fit or change the secondary optics on site, two very long screws are loosened from the back of the luminaire body, allowing the front casting to be removed. The IP66 rating is achieved by soft silicone rubber seals between the back of the secondary optics and the primary lens. The secondary optic is clamped in place with a single central screw fixing, thus compressing the gaskets.
This detail leads to the most surprising aspect of the design, as water is allowed to run through the luminaire while apparently maintaining the IP66 rating. The rationale for this is that it allows add-on optics to be changed in a foolproof way that does not compromise the IP rating.
The front casting has built-in recesses so that the secondary optics are set back by around seven millimetres. It is understood that this detail gives improved glare and beam control. If water was allowed to build up in these recesses when the luminaire was pointed above the horizontal then it would lead to a variety of problems over time. However, channels are incorporated in the front casting allowing water to drain away from the recesses and into the luminaire body. In the sample I examined, these water channels were quite small and might tend to clog up over time with debris, but these have been increased in size in the final version. Once water has entered the luminaire body it then passes through and exits via the two fixing screw locations and the split line between the body and the rear end cap casting.
One of the most successful design details is the double action Macro Lock mechanism. This locks movement in both horizontal and vertical axes with a single screw thus simplifying and reducing the time needed for aiming.
The designers have developed the RISE range so that individual RISE luminaires can be mounted together to produce multiples each with different optics aimed independently. The singles and quad versions can be combined on the same mounting brackets to achieve very high lumen outputs. When each luminaire is aimed in a different direction the visual effect is somewhat reminiscent of Pixar’s animated robot Wall-E, but as a lighting tool there is nothing else on the market that comes close in terms of flexibility and output.
It is understood that the RISE range was designed in-house from the ground-up at EcoSense with Robert Fletcher as Lead Designer and influenced by Mark Reynoso, Paul Pickard, Cristina Rodrigues, Mustafa Homsi, Jason Kim, Jacob Hawkins, Sana Ashraf, Andy Stangeland and Elizabeth Rodgers.
The ultra short two-week delivery lead time for orders in North America is possible due to the highly modular nature of the design and the assembly location just across the border in Mexico.
RISE is a remarkable piece of design and incorporates some details that would make me a bit nervous but clearly a great deal of engineering resource has been invested in its development, which should ensure a long working life without issues.
Due to restrictions between Color Kinetics and EcoSense it is understood that no colour changing LED versions can be offered for a period of time. Fixed colour dichroic filters are available, which do provide a good selection, but the efficiency is quite low for some colours, notably blue.
The high lumen output, small size, flexibility and wide range of optics, including the very narrow five-degree primary lens of RISE should allow the range to be frequently specified and commercially successful.
