Light Pushes Stuff - Late Interactive
An interactive mechanical light installation created by Late Interactive for Science in the City 2017.
Light pushes stuff is an artistic representation of the concept of radiation pressure. A sensor in each sphere relayed data to a central computer which in turn communicated to the winch lights.
Late Interactive is an artistic collaboration based in Malta dedicated towards creating interactive installations. The main goal of Late Interactive is to bring to life accessible and entertaining work that stimulates the audience by putting it in the driver seat and challenging it both through new concepts and unconventional aesthetics.

In the middle of Tokyo, Midtown, vegetables are growing.
They sunbathe inside a plastic greenhouse, and are living through photosynthesis and absorbing water. Leaves, roots, flowers, fruits. Their shapes and colors are their survival strategy.
They are design. Start off by touching the 7 types of lives now growing strong in the soil. Then, bathe in the design of vegetables, enhanced by videos and sounds.

LED Backlit Poster Frame - Big Naked Wall
Big Naked Wall, an online art gallery that exclusively focuses on backlit art is announcing its official launch this week with the unveiling of their “Life is a Feeling” campaign.
Big Naked Wall is a provider of large, backlit, and interchangeable artwork. The backlit aspect of the artwork is new to the art industry and is currently unique to the marketplace.
“We feel our product will resonate with designers and art enthusiasts alike. It invokes an emotion and feeling and at the essence that is what designers are selling; feeling. Our contemporary art concept allows for flexibility in design at a modest investment” says Raymond Wali, Creative Director at Big Naked Wall.
Titled “Genesis” by Zouassi, this artwork is the same as previous. However, once the lights are dimmed, you can see the visual impact these backlit frames make on its environment.
In addition to the art being backlit, it is also interchangeable. This means a new piece of artwork can be purchased without the frame and the existing image can be replaced. Big Naked Wall works with popular artists around the world to provide limited edition pieces.
The frame and artwork are self-assembled on site so they are easily shipped and can accommodate larger sizes without special handling or shipping charges.
“Our backlit art provides a new depth and impact that traditional canvas art does not. Our frame system is unique, in that you can easily purchase additional art and swap it out as desired. These pieces look great in commercial or residential applications, we are excited to bring this to market” adds Raymond.
Titled ”Colored Spectacle” by Mark Lovejoy, this is an example of the differences shown when artwork is backlit vs non-backlit.
Titled “Astronaut in Space” by Zouassi. This is another backlit art piece that showcases the deep impact that the backlighting provides on its environment. The picture below is used to show the relative contrast of when the artwork is backlit vs non-backlit.

Lighting Retrofit vs. Lighting Redesign
The revolution in industrial and commercial lighting is shepherding in a host of new LED lighting systems that are replacing traditional metal halide and high pressure sodium fixtures. As more organizations look to make this transition, their first question is whether they should retrofit existing lighting systems to utilize LED fixtures and control systems, or move entirely to a new redesign of their entire lighting configuration. As with many other facilities-related issues, this decision will be a function of personal preferences, the facility itself, and budgetary considerations.
LED Lighting Retrofit
If you are working with a limited budget and the facility does not have unique lighting needs, a retrofit may be adequate. Existing lamps can simply be replaced with LED lamps and self-contained drivers. The end result will be equivalent or better illumination with an immediate reduction in utility costs, but maintenance costs will likely be higher than with a full or partial redesign. LED lamps can be more directional than traditional bulbs, and replacing existing lamps will not solve light distribution issues or elimination of any shadows that an existing design had created.
LED Lighting Redesign
The next step up from just replacing lamps is changing all of the existing fixtures with LED-specific luminaires. New LED lamps and fixtures will likely generate greater illumination than prior-generation lamps, and this option might produce an environment that is overlit. Moreover, replacing the fixtures will not readily facilitate the addition of advanced controls for the LED lights, such as dimming and custom adjustments of individual fixtures.
LED Lighting Retrofit vs. LED Lighting Redesign
A complete lighting system redesign will impose the highest upfront cost on an organization, but that cost can be more quickly recovered through utility and maintenance cost savings with a redesign than with a simpler retrofit. Design engineers will analyze the space that need to be illuminated and will sketch out a customized plan that includes a blend of different LED fixtures to achieve optimum lighting in the facility. LED’s are available in a variety of light dispersion patterns that can be mixed and matched to uniformly light a facility with a minimum of dark spots and shadows. The engineer can also incorporate advanced control systems into a new LED lighting design that allows a facilities operator to selectively dim or adjust individual fixtures to alter facility lighting to coincide with particular or changing uses of the facility.
LED lighting technology has advanced rapidly over the past ten years. Decisions about retrofitting or redesigning a lighting system should be based on the most current available information. Manufacturers and designers of LED lighting systems have also gained considerable experience in that time with helping their clients to make the best lighting choices that fit their needs and that do not go over budget. That experience extends to adapting specific color temperature and color rendering indices (CRI) into new lighting systems that can improve employee morale and performance with lighting that better matches natural sunlight throughout the day.

The 5 Biggest Myths in LED Lighting
In their early stages, most new technologies are the subjects of myths that are either exaggerations or inaccuracies, if they are not altogether incorrect. LED lighting has been the subject of many myths since the first installations of LED systems appeared several years ago. Many of those myths denigrated LED lighting on the basis of cost and performance. As LED technology has improved, early-stage problems have disappeared but the myths have remained. Rather than falling prey to those myths, organizations that are considering LED lighting for their own operations should base their decisions on objective facts about modern LED lighting systems.
Myth: LED lighting is expensive.
Fact: As with many new technologies, the first generations of LED lighting systems were costlier than traditional metal halide or high-pressure sodium alternatives. Upfront acquisition and installation costs have since fallen dramatically and LED retrofits or new installations can now be completed at competitive price points to those traditional systems. Moreover, LED lighting generates the same or better illumination with substantially lower power input. Upfront system costs are usually recovered very quickly from utility cost savings alone. Myth: Light from LED bulbs is too harsh or bright.
Fact: New LED bulbs and control systems give operators much more flexibility to alter the color temperature and color coordinated index (“CCI”) of LED illumination to tone down the perceived harshness that might have plagued earlier LED systems. Modern fixtures and lenses also help to disperse lighting and to reduce glare from brighter bulbs. Myth: All LED bulbs are identical.
Fact: LED bulbs include more complex technology than incandescent or fluorescent fixtures. Quality LED manufacturers push that technology to produce better and longer-lasting products that incorporate features such as advanced thermal control and more stable electronics. Some LED systems might cost less than others, but those lower-cost systems might not have the newest technology that creates improved lighting performance. Myth: LED lamps never need to be replaced.
Fact: LED’s last substantially longer than traditional lighting fixtures, but the will need to be replaced at some point. On average, LED bulbs will perform above a minimum illumination level for 50,000 hours. Many continue to generate light beyond this average lifespan, but their total light output will be lower than when they were first brought into service. Facilities that install LED lighting systems will continue to need to plan for maintenance and replacement, but those needs will be substantially reduced in comparison to traditional lighting. Myth: LED lighting is bad for your health.
Fact: Doctors’ groups did criticize early generations of LED light that had high concentrations of blue-wavelength lighting. Lighting in that wavelength tends to keep people alert and to interfere with circadian rhythms and sleep patterns. Newer LED systems have controls that allow operators to reduce blue wavelengths in favor of more calming orange or yellow lighting. Therefore the early criticisms are no longer as valid. Myth: LEDs have sub-par color rendering index properties
Fact: Incandescents have a perfect color rendering index (CRI) of 100, so when alternative energy-saving lighting solutions like fluorescents came to the market, people were disappointed in the quality of the light. And rightly so. Many compact fluorescents have a low CRI of 50. Most LEDs have a solid CRI of 80, with High CRI options available when color rendering is very important (like in restaurants, retail stores, galleries, etc). Our LED MR16, for example, has an incredible High CRI option of 95, so colors appear as vibrant to the eye as under broad daylight. Source: specgradeled
