Seeing A 20,000 Watt Light Bulb Light Up Is Totally Blinding

Video: I don’t know what 1000 suns actually looks like in real life, but I would imagine it’s probably something like lighting up this 20,000 watt light bulb to full, world-scorching power. It’s that eyeball-burning and -blindingly bright. Photonicinduction tested this 20kW Halogen light bulb that’s used for large scale film sets indoors — where it can flood out an entire room in white light — and outdoors — where it can pretty much turn night into day. I’m not even joking.


This Spinning Illusion Is Obviously Some Sort Of Light Magic

Video: I don’t know how these tiny dancers got trapped inside this spinning zoetrope but it’s the only explanation I can come up with for this incredible light animation. Their movements are so smooth, and the shining light captures the grace of their dance so well that I’m sure some sort of magic has to be at play here.


These Images Were Taken With An Entirely New Kind Of Photography

These beetles may look like two different species, but they’re the same individual. The difference lies in how they were photographed, using a new lens that allows scientists to “see” one of the most fundamental properties of biology: Chirality.


Inside Sydney's New Cathedral Of Light

Image Cache: The annual “light, music and ideas” festival Vivid Sydney kicks off in Circular Quay today. This year, it’s constructed a giant tunnel, known as the Cathedral of Light, which runs along the edge of the Royal Botanic Gardens — and there’s a rather large surprise waiting at the end.


Scientists Discover A Weird New Type Of Light

Not all light is made equal. Now, a team of physicists has discovered that photons can travel differently to any other light that scientists have seen in the past.


What It's Like To Look Straight Into The End Of A Rainbow

Video: There’s no pot of gold at the end of the rainbow but there are some colourful visuals that you can trip out on if you can figure out how to stare the right way. Here’s a video that supposedly shows a camera gliding through the spectrum of a rainbow and making its way through ROYGBIV backwards.


Scientists Made LEDs 60 Per Cent Brighter By Copying Firefly Lanterns

A team of researchers has managed to boost the amount of light an LED emits by 60 per cent simply by etching its outer surface to resemble the outside of a firefly’s lantern.


Laser-Powered Balls Can Haul Heavy Loads Across Water

They don’t look much, but these little black balls harness the power of bright light to zip across the surface of water — pulling up to 150 times their own weight in the process.


A New Solar Cell Generates Electricity From Rain As Well As Light

Rain means clouds and clouds mean less sunlight. That’s bad news for most solar cells, but a new design can actually make use of rain drops that fall on its surface, allowing it to generate electricity even when the weather’s bad.


The World's Smallest Optical Switch Uses Just A Single Atom

Turning off a light just became a much smaller task. A team of researchers has developed the world’s smallest optical switch, which uses just a single atom to control the flow of light.
