Nanoleaf's modular, stick-on lights take your mood lighting to the next level, but I have a few suggestions for making setup ...

Govee's Permanent Outdoor Lights Prism packs three independent LEDs in each puck, and each LED can produce red, green, blue, ...

Controlling light at dimensions thousands of times smaller than the thickness of a human hair is one of the pillars of modern ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

Sorting algorithms are a common exercise for new programmers, and for good reason: they introduce many programming ...

It’s been a while, and though the basics are the same, Apple Home and Google Home have both benefitted from some long-needed ...

It turns out the "10-year lifespan" printed on your LED box is often a total fantasy. I spent years falling for the marketing, only to end up standing on a ladder every six months replacing bulbs that ...

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.
