City of Seattle to Finish Conversion to LED-based Street Lights This Year
SSL Design News Staff
March 11, 2014...Seattle City Light, the city of Seattle’s electric utility, plans to
finish converting its high pressure sodium residential streetlights to LEDs
this year. Seattle City Light performed a thorough evaluation of LED lighting
and further tested the LED lighting in pilot projects before deciding to switch
all of the city's street lights to LEDs.
The LED street lighting that the city chose reportedly offers between 48 and
62 percent lower energy consumption than the high pressure sodium luminaires
depending upon which of the HPS models that were originally installed in the
mid 1980s. Not surprisingly, the high-pressure sodium luminaires are failing.
According to the company, LEDs will provide better service reliability and
lower maintenance costs.
In addition to lower electrical usage, the city points out that the new LED
luminaires will require fewer service vehicle trips for repairs. Also, the LED
fixtures are expected to provide three to four times longer field life than
high-pressure sodium luminaires. Seattle City Light notes that overall, LED
street lighting is a more robust solution that is not affected by truck and
roadway structure vibration. Furthermore, the LEDs reportedly provide superior
color rendering with cooler white light than the HPS lighting they replace.
Seattle City Light asserts that this improved light quality improves safety
because the improved color rendering and light quality also improve the depth
of field and peripheral vision without distorting color.
SCL used Retrofit Financial Analysis Tool from the US Department of Energy
and the Municipal Solid-State Street Lighting Consortium to estimate the simple
payback for LED conversion of residential lights at 7.7 years. According to
these estimates, once all the city's residential fixtures have been replaced,
they will save the city an estimated $2.4 million in annual energy and
The LED conversion began north of the Ship Canal in 2010 and continued to
the north service boundary. In 2012, the project converted residential
streetlights from the south service boundary to Brandon Street. Remaining work
will be completed between Brandon and the Lake Union Ship Canal by the end of
2014. Lights that burn out are replaced by an LED-based version.

SSL Design News Staff
March 11, 2014...Theatre de Vest in Alkmaar, the Netherlands, was set to be completely
refurbished and needed a lighting fixture that would make the theatre stand
out. Theatre de Vest is an attractive location for hosting small or big
theater, dance, and music events. Martin Lursen, the technical manager at
Theatre de Vest, found the Moodspot from TDE-lighttech. He instantly knew this
LED spot could take Theatre de Vest to the next level.
"The Moodspot is the first LED spot that can dim all the way down to 0%
and has a colour temperature that shifts from 4000K-1400K. These features give
me endless options and allow me to create any mood I want," explained
Lursen. "After the renovation numerous colleagues expressed their
admiration for choosing the Moodspot as general lighting in our main theatre
The theater hall is lit with 56 pendant versions of the Moodspot that are
used as general lighting. Each of the seven rows of 8 Moodspots are powered
with a 240W power supply. They are directly driven via DMX512, addressed
separately and controlled in two-channel mode. The Moodspots can create a
multitude of moods with the color tone that can be controlled separately for
each row. The luminosity in the centre of the theatre hall is an average of 150
lux at a color temperature of 3000K.
LED Street Lighting in Detroit Outlasts Copper
SSL Design News Staff
March 6, 2014...LED Street lights along I-94 in Detroit have not been working, according to
a recent article
in Deadline Detroit.Less than a year ago Detroit installed LED street lights
along I-94 from Conner to Eight Mile Road, and the Michigan Department of
Transportation spent about $3.2 million on the LED luminaires and their
installation. Strangely, the LED-based lights have been going out at night and
staying on during the day. Sometimes even after costly repairs, the lights
continue to not work properly.
The problem according to the reporter Scott Lewis who looked into the
malfunctioning lights has been copper thieves who have stolen the copper wires carrying power to the street lights. This rash of copper theft has reportedly also
caused power outages for freeway cameras and message boards.
GE Albeo™ LED Lighting Installed at Natural Grocers’ Stores and Distribution Center
SSL Design News Staff
March 4, 2014...Natural Grocers by Vitamin Cottage installed all LED lighting in its
distribution center and new grocery stores. The company selected GE’s
Albeo™ linear lighting fixtures and LED high bay lighting fixtures. The
LED lighting is expected to reduce Natural Grocers’ energy usage by more
than 1.7 million kilowatt hours (kWh) annually across 40 locations and its
distribution center. With estimated maintenance savings, this translates to a
total savings of nearly $193,000 each year.
“Using LED lighting saves energy and reduces maintenance and recycling
needs, allowing us to focus on what we care about—offering the best to
our customers while reducing our impact on the environment,” said Kevin
Stees, construction project manager for Natural Grocers.
GE points out that Albeo LED linear lighting provides a high lumen output
and has a high color rendering index (CRI) of 90+ to enhance the visual appeal
of fresh produce, prepared foods, and merchandise.
GE configured different lengths of the Albeo ALC3-Series LED lighting
fixtures to fit a variety of store formats and lighting layouts. Additionally,
Albeo products contain ‘plug-and-play’ features that the company
says simplifies electrical needs, help reduce contractor labor costs, and speed
up the overall lighting system installation.
At the distribution center, Natural Grocers replaced metal halides with
157-watt Albeo ABHX-Series LED high bay lighting fixtures with motion controls.
This provides a 93 percent energy savings and reduces overall maintenance
needs. The ABHX-Series’ has an L70 (rated life) of 100,000 hours.
However, HID can burn out after just 20,000 hours.
US DOE Announces 2013 Outdoor Next Generation Lighting Winners
SSL Design Staff
February 27, 2014...The Next Generation Luminaires (NGL) Solid-State Lighting (SSL) Design Competition recognized twenty-six commercial LED outdoor lighting products. The winners were announced the evening of February 26, 2014, at Strategies in Light in Santa Clara, California. Compared to NGL winners from previous years, the recognized products showed notable improvement on all fronts.
The Best in Class distinction meant the product stood out significantly above the others in its category that were recognized as specifiable. The Best in Class winners came from five different manufacturers and covered six areas of outdoor lighting. LED Roadway Lighting was selected for its NXT-S™ local residential roadway fixture, Juno Lighting Group for its Finia building perimeter wallpack and its PL2 series bollard, Cooper Lighting by Eaton for its McGraw-Edison Top Tier™ parking and area luminaire, Louis Poulsen Lighting for its LP ICON LED pedestrian walkway fixture, and Cree for its CPY250 canopy luminaire.
NGL outdoor entries for 2013 were judged visually on color, appropriate illuminance, light distribution, glare control, appearance, serviceability, and value. Energy efficiency and lumen maintenance were evaluated quantitatively based on required documentation, and flexibility, innovation, and controllability were also taken into consideration when appropriate. The 2013 efficacy requirements for entrants were raised by 20 percent. However, the average efficacy for the luminaires increased even more, jumping over 42 percent from 66 lm/W in 2012 to 94 lm/W in 2013. Other notable improvements were seen in light distribution and color quality, with judges noting a not-infrequent need for improved glare control.
“The Next Generation Luminaires design competition links energy efficiency with lighting quality,” said DOE Solid-State Lighting Program Manager Jim Brodrick. “To be recognized as a winner, a product has to be considered specifiable by the judges, who are a mighty tough bunch to please.”
While a total of 102 products were submitted for inclusion in the 2013 NGL outdoor competition, only 68 were approved to continue in the competition, coming from 41 different manufacturers, covering 12 different outdoor-lighting categories. Of those 68 products, 26 were chosen as “Recognized” winners and deemed worthy of specification. Six of the 26 recognized products received the additional designation of Best in Class – the largest number of Best in Class winners of any NGL competition to date.

Sedna LED Installs LED High-bays in Warehouse for Masters Exhibitions
SSL Design News Staff
February 27, 2014...Masters Exhibitions specializes in creating exciting and unusual custom
exhibition trailers, stands, vehicles and truck conversions. The firm was
looking to shift its technology throughout their warehouse facilities to ensure
high manufacturing standards. Masters Exhibitions partnered with UK-based
lighting manufacturer and wholesaler Sedna LED for the initial trial and final
installation of LED high bays.
Chris Bonwick says, “Previously it had been difficult to justify
the increased cost of LED’s against standard fluorescent and incandescent
lights." Bonwick says, now however, "… it seems that LEDs have
finally come of age and Sedna can offer products at a point that makes them
The company hoped that the replacement of its outmoded lighting with LED
lighting would reduce electricity consumption, on-going maintenance costs, and
the obvious environmental damages. Masters Exhibitions opted for 10 LED
high/low bays to replace 15 conventional lights. The high/low bays were
designed for industrial applications requiring high level light mounting. The
luminaire's long life translates into avoiding the cost of re-lamping and
renting expensive lift-equipment.
The instant-on, flicker-free illumination is compatible with the company's
PIR movement sensors. With an improved CRI (color rendering index) over
conventional lights, LED, which is normally 80+ (compared to the CRI of
conventional lighting of just 20-35) improves the ability to read labels and
barcodes. According to Sedna LED, the unit can be easily retro-fitted into
Including costs of re-lamping and maintenance, the project has saved up to
85% on the company's operating costs compared to the previously installed
lighting. Notably, fittings would regularly need replacement and lift equipment
had to be rented to change the lighting because of its height.
Chris Bonwick says, “The quality of light is certainly better for
the production team, helping them work more efficiently and most importantly
safely. Previous to the initiative, there was a yellow/green glow to the
lights, which was unpleasant to work with. Now the clean white light the LEDs
emit make the workshop a much more pleasant place of work.”
Philips Showline SL NITRO 510s Illuminate South Africa's TV, Live Music and Events Market
SSL Design News Staff
February 25, 2014...Two of South Africa's most established rental companies recently invested in
Philips Showline's high-output SL NITRO 510s led-based strobe-type lights. The
SL NITRO 510s have proven to be a popular choice for some of the country's
biggest events. The SL NITRO 510s provide 68,000 lumens and six programmable
zones for a multitude of looks. Gearhouse, technical Supplier to South Africa's
Live Event Industry, recently invested in 140x SL NITRO 510 units and
immediately supplied them to the Johannesburg International Motor Show. They
were used to light Tata trucks and buses on the Tata commercial vehicles
"The SL NITRO 510 is an innovative unit in that offers all the functionality
of a strobe, but can also be used as a static white wash," says Gearhouse's
Lighting Operations Manager, Stuart Andrews. "It also has programming
facilities that allow us to create some stunning visual effects. The unit
reduces power consumption and can save a small fortune on lamps. It also has
more features than a standard strobe so has potential for a number of purposes,
from lighting trucks on an exhibition stand, to international concerts or as
pixel mapping effects units for special events and shows. This is exactly the
kind of innovation, in terms of product that we at Gearhouse SA look for. On
the Tata stand, the SL NITRO 510s were so bright we had to run them at 60%!
They performed flawlessly and made the vehicles look as if they were glowing
"The SL NITRO 510 features an array of over 1300 tightly packed, high
power LEDs that ensure maximum output and full-field, even distribution across
1200," adds Duncan Riley, managing director of Philips Entertainment
product distributor in South Africa - DWR Distribution. "Their rugged
construction makes them ideal for touring or outdoor situations, and Showline's
standard LCD menu system along with the continuous-on operation and lower power
consumption make the SL NITRO 510 very simple to programme. In addition, the
easy to use quick-connect systems allows SL NITRO 510 units to connect together
top-to-bottom and side-by-side."
Gearhouse also supplied SL NITRO 510s to South Africa's popular televised
reality dance competition So You Think You Can Dance. "This was a big night
in South African television. The finale of the show was a big deal for our
client - production company Rapid Blue," continues Andrews. "Our
in-house LD, Robert Grobler, wanted to use something with a real kick, so we
added the SL NITRO 510s as effects strobes alongside other fixtures. I expect
live events to be the SL NITRO 510's forte - without a doubt the compact size
belies their stunning output - they are blindingly bright!"
At about the same time MGG Productions, which also supplies lighting to
events and productions across South Africa, purchased a number of Showline's
NITRO 510s and supplied them to the live music concerts - Afrikaans is Groot,
which attract some of the biggest names in African music.
"The Afrikaans is Groot production team asked for an additional 'stab'
lighting effect, and I knew the SL NITRO 510s would offer just that," says
MGG's Mark Gaylard. "They worked very well for the live show and looked
especially great on TV. The SL NITRO 510s are easy to rig with some very nice
solid rigging hardware included, either flown or on the floor."
Gaylard discovered the SL NITRO 510s on the Philips stand at Frankfurt and
immediately ordered a batch from DWR Distribution.
Chroma-Q Inspire Luminaires Wash Historic Pieterskerk in Whites and Colors
SSL Design News Staff
February 25, 2014...In the Dutch city of Leiden, the historic Pieterskerk building recently
installed 70 of the new, multi-purpose Chroma-Q® Inspire™ LED fixtures.
The luminaires were purchased to provide flexible lighting for the former
Church's huge nave. The Pieterskerk is a Leiden landmark that can be seen from
afar. Construction on the Pieterskerk, which is a late Gothic style basilica,
began around 1390 and continued at various intervals until the 1560s.
The deconsecrated building now serves as a major venue for TV recordings,
corporate events, concerts or education. Since 2001, the building has undergone
major renovations to convert it into a technologically advanced space. The
venue's directors wanted to upgrade the building's lighting to enable the
creation of a multitude of atmospheres for its varying usages. They approached
Netherlands-based Harry de Kort at The Light Connection, to design and complete
The new luminaires had to be powerful enough to light the massive space. At
the same time, the luminaires had to be flexible enough to meet all the
requirements of a venue with such a variety of uses. “Not only did
the fixture have to be able to create both bold and subtle colors, but it also
had to produce a white light of high enough quality to illuminate activities
such as exams,” explained Harry. “From a practical
perspective, they needed to reduce the venue's energy costs, look good, dim
very well, and be very quiet in operation. It was a huge ask in a single
fixture, but the Inspire delivers on every level.”
The Chroma-Q Inspire has a fully homogenised beam to deliver mixed soft
pastels, bold saturates and clean whites. The unit has an extensive RGBW
color-mixing palette that enables DMX control. According to Chroma Q, the
compact LED design provides reduced maintenance and running costs, with
convection cooling keeping the fixture silent.
“The technicians, advisors and the director of the venue were
amazed and blown away by the high output and pleasing exterior appearance of
the Inspires,” says Harry. “The housing of the fixture
merged very well with the beautiful interior. It was a unanimous decision to
invest in the Inspire fixtures.”
Harry demoed the Inspire fixtures using a Jands Vista console.
“The producer of the events at the venue, Jaap, was also very
impressed by the Jands Vista control system, so Pieterskerk also decided to
invest in a Vista M1 console with 1024 DMX channels and an Ethernet node, to be
able to control all the lights individually or simultaneously.”
“I attended a presentation at Pieterskerk in January 2014, and the
Chroma-Q Inspires have transformed the atmosphere of the venue,”
said Harry. “Everyone continues to be impressed by
The Chroma-Q Inspire and new Inspire Mini™ fixtures range will be
showcased at Prolight & Sound, Frankfurt in March on the stand of UK
dealer, A.C. Entertainment Technologies (stand location 9.0, E63).
