If you didn’t receive this week’s newsletter, you will be delighted to know 299 Lighting are now supplying a sound absorbing luminaire range. These exciting new products from our German manufacturer Lightnet, are a solution to a high level of noise in open offices and public spaces. The new acoustic range is a result of work with Akustik plus GmbH, a specialist in acoustics, offering the best available materials and experience in the industry. There are a wide range of material finishes for the sound absorbing luminaires, from contemporary white to a dark walnut finish.

 

Why the need for Acoustic Luminaires?

Although acoustics is often given a low priority over other project goals, it is still important to give a satisfactory noise level in workplaces or public spaces. Noise can come from outside traffic, machinery such as photocopiers or telephones and voices within the workspace. For example, a public space such as a library, minimal noise is of great importance and sound absorbing luminaires can help achieve this.

 

How do they work?

If sound is not absorbed, it will continue to bounce around off of walls until drained of energy. In a room with hard walls, this bouncing can go on for quite some time. To put simply, the porous material in the luminaire traps and converts the sound to a very small amount of heat. This reduces the echoes reflecting in a room, making it a quieter environment.

LED Growth Vs Incandescent

29th April, 2014

bulbs

Do we truly understand why our governments are pushing out incandescent bulbs and driving us to buy the more expensive replacement LED versions? Are we getting value for money or are we falling for another marketing scam?

 

To begin with, why are incandescent bulbs been or being phased out, the US department of energy have published figures from the phase out and promote the fact that the country will be saving up to $6 billion by 2015 from the removal of 100v and 60v incandescent bulbs. This a huge saving to the home owner as well as an environmental positive in a world filled with green conscious people. This push forward replicates our governments want for the world to become more environmentally conscious.

 

The Figures are being published to show the massive saving the ban could create for the household, but the argument is what should buy now your £1 60W incandescent bulb are not available. LED is being pushed to be the future for light

 

ing but can the consumer understand the massive jump in price? There are now scary reports that some LED alternatives are not what the packaging says and some are just plain dangerous. Even the Daily Mail is picking up on the fears of the consumer saying through their independent testers that one in four of the LED bulbs don’t replicate the figures shown on the box for lifespan. Lux Magazine is also backing that some of the bulbs are not

 

This is painting a bad name for LED bulbs but most importantly shows that buying cheap means buying twice. If you scroll through the world of YouTube you will find multiple videos of people showing how dangerous some China imported LED lamps are, some lacking basic electrical knowledge and live wires are being attached directly to the front plate. Just plain dangerous.all what they seem, one expert even jokes that he has seen bulbs with both 30,000 hours and 50,000 hours lifespan on the same box.

 

Ok, yes the LED market is a bit scary right now but I do truly believe that LED is the correct direction for the UK to move into. Yes, right now people are trying to jump on the band waggon, produce faster and sell even quicker. But, the correct lighting companies have produced a reputation for excellence through decades of experience, and now are using the experience to design and produce the future for lighting with LED. This is what I believe can be the pivot point of the ban, by knowing what you are buying.

 

Conclusion

 

The most important message is to know what you are buying and only buy from trusted manufactures.

Future of Lighting? – Philips’ OneSpace

1st April, 2014

 

Philips has now been named in the top 50 of most innovative companies for 2014 by Fast Company, but they have now released the concept of ‘OneSpace’ which could allow them to climb the ladder even faster. In 1964 Issac Asimov for the New York Times wrote about predicting the future with his ideas about what will be shown by the 2014 World’s Fair. The amazing thing about the article is that there is a glare of truth about what he said in specific reference to the reveal of Philips’ new product.

 

‘One thought that occurs to me is that men will continue to withdraw from nature in order to create an environment that will suit them better’ – the ‘OneSpace’ does exactly that. The light that is created during a perfectly delicate overcast day is exactly what the ‘OneSpace’ proposes to replicate in the indoor environment. The made-to-measure panel system is designed to create a uniform, glare free light which will cast no shadows.

 

The ceiling which is most commonly left out by architects as an important design element of a building can now be enlightened to make it a feature of any project. The product is being suggested to be used in areas which are formidably known for poor lighting. Phillips now claim they can ‘deliver glare-free LED light that eliminates shadows completely so you can view objects in their true light’ for areas such as car showrooms, retail stores or airports.

 

The seamless panel’s sizing starts from 2.4m2 and is available up to 3m by 10m. The ‘OneSpace’ is manufactured using LED lights with a diffused cloth in order to create the authentic looking natural light. It will be supplied with a colour temperature of 4000k, but Phillips say that the panel can be adjusted between 3000-5000K to achieve the perfect look for a room. The light also scores 80+ in CRI, reiterating the idea of the natural looking light the panel is producing.

 

Is the future of lighting being create by Philips or just another concept which will be lost in the past?

Lighting In a Retail Showroom – Durasafe, Singapore

6th March, 2014

 

A view of the frontage of Durasafe

 

Durasafe is a fantastic safety wears retail company based in Singapore; they brought to us a very interesting project. It was set up directly with the client in late 2013; this was an exciting time for 299 as it would be our first export to an Asian country. The initial stages of the project were to look through the CAD drawings and decipher which fixtures would work best and meet the client’s requirement.

 

For our lighting designer, this left him a large scope for creativity, the brief set by the client was to use architectural lighting to enhance the aesthetics and create a contemporary looking showroom. The fixtures would need to create an environment that the Durasafe customers would feel accentuated the feeling of safety but also help in the selling process.

 

The two suspended fixtures chosen for the project were the Sark profile system and Clyde profile. The style of the Clyde meant it was an ideal feature pendant to be placed in the waiting room; the client expressed strong appreciation towards the quality of this product. The Sark profile is a direct/in-direct feature which as you can see is used above the workstations in the showroom, the high ceiling have been illuminated by the in-direct light and create a real feeling of space within the Durasafe showroom. Both these fitting were delivered in a custom RAL colour matching the clients specification.

 

As you can see from the images the project has been a huge success. Here at 299 we are very excited to see further project to being created out of Singapore and hope we can work with a client like Durasafe again.

Helping you to understand more about lighting – CRI

25th February, 2014

CRI_Diffrence_Blog

In the last post we had a brief look into the definition of colour temperature and how it is best used in varying locations. Today’s post will be looking into colour rendering index or CRI.

 

I feel the best way to describe the CRI rating of a lamp, is its ability to light objects as realistic to daylight as possible. Listed below are the three defining features of good CRI;

 

-       Produces a great variety of colours

-       Creates contrasting shades of colour

-       The objects look naturally lit

 

The CRI of a lamp does not always coincide with an object looking the same as how it looks in daylight. To create this you have to balance both the CRI and the correct colour temperature. For example if we look at a light source such as a candle, it has a CRI of 100 meaning it will create the differences in the chromaticity’s of 8 CIE standard colour samples (or in simple terms the eight distinctive colours in the light spectrum). Even though a candle flame has the ability to show the differences, its colour temperature is very low (1700ºK). This means it struggles to show the blue colours in objects giving a less realistic light. A colour temperature that is going to match natural daylight best is between 5000ºK-6000ºK with a CRI of over 95.

 

Even though CRI is usually measured between 1-100 there are some instances where the CRI comes out as a negative figure, for example low-pressure Sodium lighting. If we are looking at lamps that are more likely to be used around the house, a typical residential LED fitting or bulb usually has a CRI of 80+. When testing for the CRI, the lamps are split into various groups called Correlated colour Temperatures (CCT) to be tested at different temperatures. The groups are split into three groups depended on the temperature range up to 2700ºK, 2700ºK – 6000ºk and over 6000ºK. If this is under 2700ºK a Blackbody radiator is used in place of natural daylight as the control.

 

I hope this post has increased you knowledge a bit more in lighting terminology, more helpful posts to follow…

“Light is the first element of design; without it there is no colour, form, or texture.”

Little_lamp_in_dark_room

 

 

No matter how much time you spend on making your house look the way you want, if the lighting is not correct you will never get that perfect look. The way in which the light interacts with objects it comes into contact with alters the way in which YOU see them. Thinking about how your room is lit should be the building block to creating the design you are looking for.

 

To begin with lets have a look at some of the basic terminology used. Colour temperature is a good place to start, what is this and how is it used?

 

Colour temperature is measured in ºK (Kelvin), the lower measurements starting at around 1000ºK is the light that creates a red tinge to the object. If we look at light temperatures that top measurement scale they are around 7000ºK this gives a blue tinge to the light and is suppose to replicate daylight. The higher the temperature the more artificial the light starts to look. To finish the mid range light becomes white light at around 5000ºK.

 

Now, this may all sound a bit confusing but lets bring it back to simpler terms at which temperature you are looking at for different situations. If your looking at refitting an office light you will be looking at a colour temperature around 4000ºK, this is giving you a bright daylight look to the lamp. If we go to the complete end of the scale a large warehouse which needs a very clear line of sight will use around 7000ºK giving a very bright and cool light. The temperature which is going to make you feel most at home is between 2700ºK to 3000ºK, this is a much warmer light then used in both the office and warehouse.

 

Have a read next week when we will look at clearing some more of the technical terms for you.

Magnic Light iC – Contactless Dynamo Bike Light

20th January, 2014

Kickstarter currently have an interesting use for the LED; bicycle lighting. The hassle of finding that AAA battery in the morning when your light has decided to die over night is no more, with the introduction of the Magnic Light iC. Using eddy currents created by the strong magnets included in the product mean that it can run off the potential energy created through a turning wheel. This might sound like old hack but here is the clever part, that the product is contactless. The gap between the wheel and light will allow you to slide a card between them, thus removing all resistance to the wheel.

 

All this is very interesting especially for the urban commute. Winter mornings filled with darkness can be daunting, but with this clever gadget you are no longer in the dark. At a mere 60g the unit will not affect the weight of the bike and the shock-resistant polycarbonate outer shell shows a quality build. The technology within the product means that the light will flash and still run while breaking and waiting at lights.

 

The Kickstarter campaign has gained a lot of interest and now has just under $150,000 worth of funding which will mean that it can now be pushed into production. The Kickstarter pages goes into great detail about the technical aspect of the product and who the Cree LED produce such a high lm/W.

Why Restaurants Love LED Lighting

5th September, 2013

restaurantsled

 

Restaurants have large overhead costs to consider like everyone else when balancing the books of their business, and their energy bills are a big priority.

 

Besides powering kitchen appliances such as cookers and storage facilities, lighting and computing requirements, restaurants are one of the biggest user groups of electricity across the world. In the USA for example, the annual energy bill for the commercial food sector is estimated to be around $10 billion, according to ‘Energy Star’.

 

To keep running costs down, and reduce the carbon impact on the environment, several chains and sites are making the change to LED lighting.
