Modern, energy-saving bulbs use a lot less power to produce the same light. So, now brightness is measured in lumens (shown as lm). The higher the number of lumens, the brighter the light. The brightest light bulb can be 1525lm or more, while the dimmest is around 200lm. Approx run time from full charge: 18 hours (static colour/colour change modes), 7 hours on bright white and warm white settings as these are significantly brighter Shape of Light reveals photography’s role in a wider history of abstraction. The photographic artists in the exhibition have engaged with advances in abstract art across a range of art forms; from painting and sculpture, to film and installation. At times these photographers have responded to new discoveries by their peers working in different media. Occasionally they have pre-empted them. When I finished setting up my leaf design, the light strip was around 2 feet too long. At first, I thought I would have to reconfigure the design to accommodate the extra length, but after reading through the instructions, I realized the strand is actually trimmable. This] is really the first clean and clear experiment where the speed of photons in structured light beams is directly measured,” Leonhardt says. Now that physicists understand it, they might be able to exploit it. “I do not foresee immediate applications in the short run, but important fundamental physics always has implications and applications in the long run.”
The inner cone boundary line indicates the point at which light from the spot will start to blur/soften;

The team revealed this oddity by studying two kinds of shaped light: a Bessel beam, which looks like concentric rings of light, and a Gaussian beam, which spreads out as it travels. They used an ultraviolet laser to produce pairs of photons and passed one photon through a filter to shape it into either a Bessel or Gaussian beam. Both travelled 1 metre before hitting a detector, so they should have arrived at the same time, but the shaped photon was a bit delayed ( Science, doi.org/znr). The shape of the light can be represented as a rectangle and changed with the “X” and “Y” values. Square : In 1924 French poet André Breton published the first Surrealist Manifesto. Surrealism hoped to revolutionise human experience by rejecting a rational vision of life in favour of one that valued the role of the unconscious and dreams. Its writers and artists found beauty in the unexpected, the overlooked and the uncanny. Money-saving: they're more expensive to buy, but they can pay for themselves in energy savings over their lifetime. And their smart functionality can help to reduce electricity usage. For example, lights can automatically be dimmed in the evening or can be combined with smart motion sensors, so lights are turned off when no one is in a room. It’s well known that light travels at different speeds as it passes through different materials; it travels more slowly in water than air, for example. But the speed of light in a vacuum, at a little under 300 million metres per second, is an unwavering constant that underpins much of modern physics, including Einstein’s theory of special relativity. It’s so important that physicists give it a special letter: c.
The world we see is made of light reflected by the things we look at. Photography records this light, holding and shaping these fleeting images. Shape of Light: 100 Years of Photography and Abstract Art explores the history of artists who have worked with light to create abstract work. These photographers prioritise shape, form and expression over recognisable subject matter. Some use the camera lens to transform reality. Others work with photographic materials to create images with little obvious reference to the real world. Multiple dimming options available: Non-Dimmable, Wireless dimmable, 1-10V dimmable, DALI dimmable and TRIAC mains dimmable. Personally I think that’s a useful concept, though the scientific rigour police might not welcome it,” he says.

E10 – an Edison screw, 10mm in diameter. Used in decorative lighting such as chandeliers (also referred to as an MES – miniature Edison screw). This room presents found abstractions lifted from nature and the urban environment and repurposed for the gallery wall. Through selection, framing and emphasis of tone and contrast, photography casts a new light on the everyday. These photographs encourage us to look closer. They present peeling paint and scratched surfaces as worthy of aesthetic appreciation. a “Watt equivalent” which is neither the electrical power they require nor the amount of light they put out. Lights with larger size have softer shadows and specular highlights, and they will also appear dimmer The works included ranged from ‘accidental’ abstractions to experimental photographs that sought to break new ground. The variety of images spoke to photography’s complex relationship with abstract art. In fact, some of the artists shown questioned their inclusion. American photographer Minor White wrote to curator Grace Mayer to express his concerns: ‘I feel that these photos of mine that you have chosen are not abstractions in any sense whatsoever. True they resemble paintings that go under this title, but this is coincidental, not intentional.’
