You should be able to bend the light and raise it up or down to get the most flattering light for whatever you’re shooting. People who wear glasses, for example, might need to raise the light and adjust it at a steeper angle to avoid glare and reflections.
Dopo il successo dell'edizione precedente nel 2023, che ha visto la partecipazione di 38.713 visitatori e 812 espositori, SPS torna nel 2024 con una fiera ricca di contenuti e iniziative imperdibili. Diviso in 6 padiglioni, l'evento copre una vasta gamma di argomenti focalizzati sulla trasformazione industriale, sia in termini di digitalizzazione che di sostenibilità. Questi due concetti sono cruciali per l'evoluzione e la competitività dell'industria moderna. I padiglioni 3, 5 e 6 sono dedicati alle tecnologie di automazione e alle soluzioni digitali innovative per l'industria 4.0, mentre i padiglioni 4, 7 e 8 ospiteranno il percorso dimostrativo del District 4.0.

RingLight with Stand
We still recommend these models if you can find them in stock. But if you can’t track them down, here are some tips that will help you choose a suitable replacement among a sea of similar-looking lights.
For anything else, a 14- or 16-inch ring light will do. These larger models should suffice if you want to keep the stand off of your desk or you plan on using the ring light while standing. The 14-inch ring lights we tested, including the Neewer 14-inch and Yesker 14-inch, were plenty bright in our testing. A 16-inch ring light, such as the Neewer 16-inch, would be brighter. But that extra luminance is really only useful if you’re going to position the light several feet away from you.
But going too big causes issues, too. On the flip side, the 18-inch models were overkill: They were so bright that they created washed-out images at all but the lowest brightness levels.
Lighting plays an important role in the image quality of your videos and photos, second only to the quality of your camera. But you don’t have to invest in a complicated lighting rig to get better close-ups.
Without it, you can look grainy, out of focus, or even shadowy—like an anonymous witness in a true-crime show. A ring light is a simple tool whose diffuse glow can bring you out of the dark and make you look more professional.
CRI is one measure of light quality; the higher the CRI (the closer to 100, the better), the more colors the light can render and the more precise the image is color-wise.
More flexibility is always better. Bonus points go to ring lights—such as the Yesker 14-inch—that include a flexible gooseneck mount for your phone; this is great for getting the angle of your phone just right too.

Find the right temperature for your skin tone. Wirecutter’s Rago said that warm light generally works best for most skin tones, but if it’s too warm, a person could look orange. Bluish light can make a pale person look lifeless.
Wirecutter is the product recommendation service from The New York Times. Our journalists combine independent research with (occasionally) over-the-top testing so you can make quick and confident buying decisions. Whether it’s finding great products or discovering helpful advice, we’ll help you get it right (the first time).
Our tests showed that a Bluetooth speakerphone won’t necessarily produce better results than a smartphone. But we found a few models worth checking out.
For desktop use, a 12-inch model is best. If you plan on using a ring light propped up on your desk—not on a tall stand on the floor—look for a moderately sized model, like the Godox LR120 12-inch LED Ring Light. These have stands designed for desktop use and cost less than larger models.
Look for lights that can adjust brightness in 1% increments. With some ring lights, you can adjust the brightness from 0 to 100% in 10% increments (10% brightness, 20% brightness, and so on), but we prefer models that let you fine-tune the brightness to the nth degree. Some ring light descriptions will specify this; it might be called “stepless adjustment.”
More expensive doesn’t mean better quality. While researching this guide, we saw a Wescott 18-inch Ring Light that cost nearly $200 despite having only two color temperatures (cool and warm). Some ring lights cost twice as much as similar-size lights without adding more features or benefits.
More color temperature settings is better. Most of the ring lights we considered had at least three color-temperature settings: cool, neutral, and warm. We preferred those that offered more color-temperature steps between the coolest and the warmest levels; this allows you to dial in the setting that looks best with your skin and environment.
These accessories make using a ring light easier, but they’re just extras. Prioritize the features above when choosing a ring light.
Altra interessante novità riguarda l'iniziativa She SPS Italia, che si concentra sul tema del divario di genere, ancora significativo nell'ambito industriale. Questo progetto si propone di promuovere programmi di mentorship dedicati alle donne e di mettere in luce le opportunità legate alle figure professionali in ascesa.
After researching and testing more than a dozen ring lights, we’ve learned that it’s a fast-moving category with lots of brands that may be here today but gone tomorrow. Many of the best ring lights we’ve tested are either now discontinued or have recurring stock issues. This includes the Neewer 14-inch LED Ring Light (RL-14), Neewer 16-inch LED Ring Light (RL-16), Yesker 14-inch Ring Light, and Godox LR120 12-inch LED Ring Light.
It’s also worth considering the height range of the ring light’s stand. The greater the range, the more versatile it will be to accommodate all kinds of situations.
Una delle novità più rilevanti di SPS Italia 2024 è il rilascio della seconda edizione del Position Paper. Questo progetto, elaborato dal Comitato Scientifico dell'evento e composto da oltre 150 aziende italiane, rappresenta un passo significativo nell'ambito della ricerca e della diffusione delle conoscenze. Lo scopo principale del Position Paper è fornire linee guida fondamentali per comprendere l'evoluzione tecnologica e digitale del settore. Per soddisfare l'interesse crescente dell'industria, il secondo volume arricchisce ulteriormente il precedente documento con nuove approfondite analisi. La presentazione ufficiale avverrà durante la fiera e sarà integrata dai risultati di un'indagine sull'intelligenza artificiale.

More steps between the coolest and warmest color temperature levels mean more flexibility in suiting your skin and environment.
Smaller, USB-powered lights are great for mobile use. Ring lights that are 12 inches or smaller can be powered via USB, whereas the larger ring lights use an AC/DC adapter because they need to draw more power. So if you want a ring light that you can use outdoors—tethered to a laptop or USB power bank, without an outlet nearby—a ring light that’s 12 inches or smaller is ideal.
Color temperature, measured in kelvins (K), greatly affects the aesthetics of your photo or video. The room you’re in, the clothes you’re wearing, and your skin tone can all look different depending on the light’s color and temperature.
Many of the latest ring light models also have a Wi-Fi remote to power the light and adjust the color temperature or brightness.

A CRI of 90 or higher is best. Ring lights with a CRI of 90 or above are considered excellent, whereas those with a CRI between 80 and 90 are thought of as good, according to Westinghouse Lighting.

A ring light is a simple, cost-effective option that anyone can set up and use. It makes the most sense when you need just a bit more emphasis on yourself in a space without a lot of natural light and you don’t have the time or energy to invest in a pricier professional lighting setup.
Dal 28 al 30 maggio 2024, la città di Parma accoglierà l'importante appuntamento nel mondo dell'automazione e del digitale per l'industria intelligente e sostenibile: SPS Italia 2024.

A ring light is exactly what its name suggests: a doughnut-shaped light, typically made of rows of LEDs. The halo shape diffuses light over a wide area, reducing shadows and washing away blemishes for a more-flattering appearance. The space in the middle of the light is a great place to mount a camera or phone because you get an even distribution of light around the lens.
You can certainly find other lighting setups that produce better portrait or video lighting—such as this two-light kit Goodrich recommends, which includes lighting umbrellas, several light stands, and a number of photo bulbs. But they’re more expensive and more complicated to set up and break down.

Some larger models have a built-in USB port for phone charging. A few lights we tested that are 14 inches or larger had a USB port for charging your phone while it’s attached to the ring light. That’s convenient for long shoots.
In addition to a stand, most ring lights come with extras such as a carrying case for the light, a mount for your phone, and a Bluetooth remote to take a photo on your phone from a distance.
10-inch lights aren’t great for most uses. These smallest lights had stands that raised the light only an inch off the desk, creating spooky, unflattering under-chin lighting. You could prop one of these lights up on a stack of large books or a box, but we think it’s worth paying a little more for a larger, brighter light that has a taller stand.
You might not find the CRI rating in the product description, but that doesn’t mean the ring light has a low CRI. Contact the manufacturer and ask for the number. If they don’t get back to you—or, worse, they don’t have a website—move on to the next ring light you’re considering.
How far or close you put a ring light depends mostly on your comfort level and the size of the light. But I found that for video-call purposes, somewhere between 2 and 3 feet was most flattering.
