If you’ve already got too many gadgets on your desk, then this 3-in-1 ring light should be on your list.

As we opened the boxes, we first tested how quick the ring lights were to set up – because who needs a complicated setup, especially if you’re just about to jump on an important video call? We then looked at how easy they were to use and charge, by testing out the buttons and different lights. Ultimately, we were looking for lights that gave us a visible difference when we took photos and used video-conferencing systems.

If it’s your job to create professional-looking photos or videos, you may want to splash the cash on this high-tech ring light. The 19in light, with true bi-colour, is heavier than all the other lights in this round-up, but its quality is far better than the average Zoom light.

Taking a good selfie really is all about the lighting – too bright and you may look over-exposed; too dark and what’s the point?

The cheaper choices are designed for social media and videos calls, and will often come with small tripods and a few different light settings, though not very high-quality ones. The more you pay, the better light source you’ll get.

You also need to think about how much space you have. Say, if you have a tiny desk, which barely fits your laptop, a tripod setup may not be wise, as it will take up too much space.

The price may be steeper than the normal ring light, but the kit does include an easy-to-attach stand and a phone holder. However, if you’re a beginner, it may be best to start with one of the more basic ring lights and move on to this when you’ve got your first commission.

The frosted-lens light has 96 LEDs with a 120-degree beam angle, which gave our zoom calls a very bright look. However, you can easily use the buttons to change between cool, natural or warm, depending on how sunny you want to look that day. You can also change the brightness by between 10 and 100 per cent – we found that 60 per cent created a natural, effortless look while also making our skin glow and eliminating any shadows. Result! The ring light can be used on its own, but if you want some elevation, it can be paired with the desk stand, which easily attaches to the bottom.

A budget option if you need the light but don’t want to spend a fortune on looking good. The 6in ring comes with its own tripod, as well as a mobile attachment. We liked how easily the selfie ring could be set up – simply plug into a USB and attach to the tripod. We were also able to change the extension of the legs easily.

We loved the ease of the Zumy video conference light. There was no stress of having to put the whole thing together before we used it – we just clipped it on and plugged it into the USB, and we were ready for a call. Its light settings were easy to change and bright enough for video and photos, giving us just the effect we wanted. Plus, its reasonable price is spot on for most budgets.

If you’re using this on its own, it can be balanced on your desk, but for the best effects, it’s worth investing in one of JOBY’s accessories, such as its gorillapod stand. We loved attaching the light to it and using the flexible legs to achieve different shadows and lights for Instagram pictures. Other accessories include a phone mount and a microphone.

This attractive-looking ring light will look great next to your desk, whether you’re using it or storing it for later use. The 12in LED light has 10 brightness levels and three colour temperatures to get just the right light for you. It plugs directly into a USB, and the levels can be changed via the small remote on the cable.

Initially, we did find the different modes a tad tricky to change with the touch buttons on the base of the light, but you can also change them via the app. However, we really liked how lightweight and easy it was to pack away – especially when you need more space on weekends. If you want only a ring light, then the AirLit may be a bit pricey, but if you’re after a gadget with all the trimmings, this is a nifty piece of kit.

If you’re working with a webcam, this ring light allows you to attach it in the middle. The 10in light is also the perfect size for a workspace environment and won’t look out of place whether you have it at home or in the office.

With a softbox design that uses light-source separation and multiple layers of diffusion to create the kind of soft, diffused light you might find at a professional studio, we loved its exceptional effects while we did a quick Zoom meeting. Once we were finished, we simply unplugged it from the USB port and folded it flat to store easily in our drawer.

There’s nothing worse than logging on to a work Zoom call and having to see your sallow, shadowed face staring back at you, especially when everyone else on the call looks pristine. Of course, you can adjust your positioning, or add a filter, but investing in a ring light means you’ll always be spot on when it comes to the lighting.

The button at the back acts as a switch, but can also brighten the light, by four degrees, while the ball stability on the neck of the light means it’s adjustable to give you just the right position. We found it incredibly easy to set up and attach to our laptop, taking just seconds.
