Welcome to The LED Specialist blog. We feel that we have a responsibility to our viewers to explain the complicated LED market in order to ensure that the correct products are purchased and that cheap inferior products are not purchased which diminishes the energy saving capabilities of LED lighting.
International Student House (ISH), London accommodates
university students and interns from over 100 different countries. ISH is not
just a place to stay, it is a social and culture centre which holds lectures,
debates, themed suppers and culture nights. The ISH has its very own bistro which
by day is a busy modern restaurant transforming into a lively nightclub in the
evening. Due to its multipurpose use, the lighting installed in the bistro can
often be on for almost 24 hours a day.
ISE is committed to reducing its environmental impact and
carbon emissions. As part of an £180,000 refurbishment of the ISH’s ground
floor, LED lighting was installed in the bistro area. The LED switchover has
doubled lighting levels, reduced power consumption by 84%, delivered savings of
over £1,000 per annum and cut carbon emissions by almost 6,300kg a year. The
lighting engineers opted to use Philips’ MasterLED bulb, MasterLED spot and Latina
Latina LED Down-light
Philips’ Latina down-lighters were installed in the server
area as they fit perfectly with its new design. The costly GLS pendant down-lighters
in the server area were retrofitted with Philips MasterLED 8 watt lamps. Before
the LED switch-over the dining area was lit with over 100 50 watt halogen down-lighters,
the replacement lamps needed to illuminate the space during the day and not
impact the night club ambiance in the evenings. With energy saving in mind, ISE
opted to install Philips MasterLED spot GU10 7 watts lamps and remove the
existing energy consuming halogen lamps.
The SchoolVision system is specifically designed to enhance
the learning environment; studies proving its benefits have been conducted all
over the world.
It is well established that lighting has a significant effect
on our mood, energy levels and concentration. Using this knowledge,
SchoolVision provides an outstanding learning environment that engages and
stimulates or relaxes and calms. Pupils get the very best start in school with
light that enhances learning, improves results and makes everyone feel at ease.
In a single day, one classroom hosts a variety of activities
ranging from; focused tasks and quiet reading time to creative pursuits and
lively group work, all requiring differing levels of energy and concentration. Using
the SchoolVision touch-pad teachers can support the rhythm of activity in the classroom by switching between warm light and daylight, whatever the
time of day, whatever the lesson.
Teachers are able to chose from one of four settings;
Normal, Energy, Focus and Calm. The different ambiances are produced by varying
the balance between light intensity and colour temperature, making each setting
suitable for specific tasks or times of the day.
The Normal setting was designed to be used during general
classroom activities; light is emitted at a standard level of intensity, in a
standard colour temperature. This light level is proven to help students pay
attention. The very cool colour and high intensity light emitted in the Energy
setting helps invigorate pupils when energy levels are lacking, this is ideal
for use first thing in the morning or after lunch. The Focus setting emits
light of the highest intensity in a cool colour temperature; this mood is
designed to aid concentration during tests and challenging tasks. The Calm
setting’s warm light temperature provides a relaxed ambiance for individual
work and quiet time; it has also been proven to calm a hyperactive class!
As with all Philips products, SchoolVision adheres to relevant
lighting norms and provides comfortable light with no shadows or glare.
Daylight sensors dim the lights when there is enough natural daylight to create
the desired ambiance and presence detectors turn off the lights when the
classroom is empty. SchoolVision is also energy efficient offering savings of
up to 57%.
Epsom and Ewell High School is the first school in the UK to
have SchoolVision fitted. Results from this pilot study show that the
SchoolVison system positively impacts pupils’ concentration levels. City
University London has carried out a series of standard D2 Test Trials, in two
of the High School’s Science Laboratories. These are standard psychometric
tests which measure concentration. Focus group research with teachers and
pupils was also carried out.
The study has delivered the following results; one classroom
saw D2 test scores increase by 17 points since the implementation of
SchoolVision and the other by 40. A control group demonstrated no improvement
in concentration levels over the same time frame.
Head researcher, Dr Efrosyni Konstantinou from City
University London’s Centre for Performance at Work, highlights that, more than
anything, different students have different learning needs.
“On the whole, in qualitative interviews, both students and
teachers noted how the lighting changes positively impacted the mood in the
classroom. The benefits associated with the different SchoolVision lighting
settings included better concentration, increased alertness, enhanced
efficiency and a calmer mood which inidicate that the SchoolVision can be the
beginning to a new way of teaching and learning for future student
The findings echo those from other research into the effects
of the SchoolVision lighting system. A year long study in a primary school in
Hamburg, Germany found that, with the SchoolVision lighting system, pupil
reading speeds increased by 35%, frequency of errors fell by almost 45% and
restlessness was reduced by 75%.
A new lighting system was unveiled at Selfridges’ Project Ocean event, this campaign aimed to promote sustainable eating. To ensure its message reached an even wider audience, the luminaires were adapted to give the buildings exterior an under-the-sea effect. Although Philips' initial brief was to only provide a scheme for the external façade on Oxford Street; after seeing the benefits of the PowerCore lighting, Selfridges decided to extend the system to both Duke and Orchard Street.
Sustainability is high on Selfridges’ agenda and so any
lighting solution offered to them must deliver significant energy savings. The
department store hosts a range of events and projects and so requested a low maintenance,
energy saving lighting solution, capable of transforming the department stores
façade at the press of a button.
Selfridges’ required a lighting system adept at producing a
variety of colour and effects, using their unrivalled knowledge of LED lighting
Philips opted to install three of their flagship products; ColorReach
PowerCore, ColorBlastPowerCore and ColorGrazePowerCore. Selfridges’ key
architectural features were highlighted by the ColorReachPowerCore lamps.
Because of its compact, low profile design, the ColorGrazePowerCore LED
surface linear was used. The brief detailed that architectural lighting was
required for both indoor and outdoor applications and so ColorBlastPowerCore
luminaires were installed. These have a wide rage of capabilities and can be
positioned almost anywhere!
As a listed landmark building, Selfridges’ have strict rules
in place governing what can be affixed to the exterior meaning drilling is
prohibited. Working closely with Selfridges’ in-house electrical contractor,
Philips overcame this obstacle by mounting the luminaires using a special resin.

Philips’ new patented TransforMax technology enables Philips
low voltage LED lamps to universally replace 12v
Halogen spot lamps. TransforMax is a unique patented protected intelligent
driver concept designed to be used with 12v LED lamps. It enables broad
compatibility with existing electronic and electromagnetic Halogen
Using TransforMax technology without a dimmer
To provide an estimation of how many LED lamps can be
connected to an existing halogen transformer, the rated power of the
transformer is divided by the LED lamp replacement wattage. For
example if you are replacing a 35w halogen lamp with a 7w MR16 lamp and there
is a 150w transformer available, the calculation would be 150 ÷ 35 = 4.3 (branch
max.). This shows 4 lamps can be attached to this transformer.
Using TransforMax with a dimmer
When the LED lamps are connected to a dimmer it is important to determine the maximum loading of both your transformer(s) and your dimmer
in either watts or volt amps. Maximum loading is determined by both the system max. and branch
max., the calculation for branch max. is shown above. System max can be calculated by dividing the dimmer rating wattage by
the wattage of the equivalent halogen, for example if you have a dimmer rating
of 200w and a 35w halogen the system max is 200÷ 35 = 5.7 (system max). This shows 5 lamps can be used
per dimmer. The total number of lamps you can install is limited by the system
max, you must also ensure the transformer load is sufficient to allow for the
individual branch max. In the example provided above, although 5 lamps can be attached to the dimmer, the transformer's branch max is 4 lamps and so if 5 lamps were to be attached to this dimmer, two transformers would need to be used.
technology, the latest innovation from Philips, enables lamps to blend
seamlessly into the background due to their lightweight, sleek design. This
allows object to reveal their true colours and really take centre stage.
lamps offer superior visual comfort and maximum performance through use of a
single optic. These lamps do not have any distracting heat sink fins and so are
