LED lights have revolutionized the world of lighting, and everything is possible today. There’s a class of devices that can solve an amazingly large number of problems without you being aware of them and one of those devices is a usb led light. It’s battery-free, plug-in-free and occupies no physical space whatsoever, but can illuminate a dark laptop keyboard, a corner of a desk or a dark bedside table in seconds. Without having owned one, it’s hard to appreciate how frequently you’ll be reaching for the one that is within easy grasp.
This guide includes information on what these lights are for, the different types of lights they can be, and how to choose the appropriate light for the location and use.
What Exactly is a USB LED Light?
A USB-powered LED light is a mini lamp or strip that runs through any standard USB port, such as a laptop, power bank, wall charger, or car charger. It draws power directly from the USB, so it doesn’t require any batteries or special charging cable.
Most of these lights are based on a simple premise – simply plug it in and it lights up. No set up, no pairing, no configuration. This simplicity is one of the reasons why USB LED lamps have become such a popular accessory.
Various Forms of LED Lights
Flexible Gooseneck Lights
A flexible USB LED light has a bendable neck, letting you aim the light where needed. These are particularly popular for use with a laptop computer as you can bend the light down towards your own keyboard without disturbing others around you in a dark room while typing.
Mini Plug-In Lights
The smallest and smallest is a mini USB LED light, usually just a small bulb directly onto a USB plug without a cable. They’re useful for applications that require a strong, high-powered, short-range source of light, such as backlighting the immediate vicinity of a laptop’s USB port.
Strip and Bar Lights
Some USB lights are short strips or bars, rather than just one light bulb, and light is distributed across a wider area. These fit as a USB desk light as they can provide illumination to an entire keyboard or workspace as opposed to just a small circle.
Clip-On and Portable Designs
A portable USB light may be provided with a clip or a small stand to easily mount the light on the edge of a laptop screen, or on a headboard or bag strap. These are very popular with those who have a lot of mobility and do not want a light source which is fixed to a specific location.
Common Uses of USB LED Lights
For all of these practical use cases, it’s worth going through a few of them to understand that the utilization of the right light is dependent on what the use case is.
Reading in Bed
Being able to read in bed without disturbing the spouse. When you get in trouble in the night, you can just clip the USB reading light onto your book or connect it to the power bank on your nightstand for a lighted beam without illuminating the entire room. This is likely the most frequent reason to purchase one in the first place.
Using a Laptop in Low-Light Conditions
Using a laptop in low-light conditions. This “USB laptop light” fits directly into one of the laptop’s ports and points down at the keyboard, which is the classic lamp problem when you can’t see the keyboard when typing on a plane, in a hotel room or when the power goes out!
USB Night Light
A USB night light is a simple, soft light that can be powered by a power bank or a USB wall charger that is left on all night to provide a bit of light in a room in case it is needed during the night, such as to see the way to a glass of water.
Task or Hobby Lighting
Task or interest lighting. A USB task light that shines directly onto your work surface is a great option for tasks that require close work such as sewing, soldering, or reading small print, with consistent, glare-free illumination right where you need it.
Brightness, Color Temperature, and Adjustability
When it comes to the real light output, not all USB LED lights are the same. There are a handful of specifications that are important to watch out for before purchasing:
- Brightness levels Often, more expensive lights have several brightness options that can be changed by touching a light-sensitive button on the base. This allows you to adjust its level for evening use or to use it up bright for intense desk work.
- Some lights feature options for warm (yellowish) light versus cool (bluish-white) light choices or a full range of light in between. The warmer the color, the more likely it is to be comfortable to look at during night use, and the cooler the color, the more likely it is to be comfortable to look at during daytime task lighting.
- Flexibility of the neck or arm If you are going to turn the light around often, be sure to get one with a true bendable gooseneck not a flimsy plastic neck that doesn’t bend at all.
Energy Use and Practicality
One of the lesser known benefits of these lights is their low power consumption. Most USB models are an energy efficient LED light, and allow for a lit light to run for hours on a small power bank without you noticing significant power loss. That’s one of the reasons they’ve become a very popular accessory for traveling; a single power bank charge can power a light through an entire night or even more.
The heat produced by them is also minimal, as they do not cause heat compared to older incandescent lights, and therefore they are safe to place near books, bedding or fabric without fear of any burn hazard.
Things to Consider Before Buying
There are a few practical tips that will help you stay from getting a picture perfect light that you don’t like in reality:
- The quality of the flexible neck Lower quality lights tend to droop over time. Check for reviews that indicate longevity of the GooseNECk.
- Number of LEDs The more the light is distributed across individual LED bulbs, the better, more even the light is, and the less it has to do with one big point source.
- Cable and connector type It’s a USB light, so it will include a USB-A or a USB-C—just make sure it’s compatible with the devices you intend to use it with.
- Dimming function If you intend to use it at night, a light with a range of brightness is better than a fixed-light for the extra expense.
- Portability Larger stationary lights may not be convenient to move around with, but if you move around a lot, a smaller, lightweight lamp with a short cord will certainly be more useful.
To Whom Is It Most Beneficial to Own One?
A small USB light can solve all of the above and more. Not a fancy add-on to your toolbox, but the kind of simple, low-cost tool that you’ll end up using far more often than expected once you have it.
Final Thoughts
One of those little items that you don’t hear much about until you have one and then you just grab it whenever you can. There are lamps that can be used for reading late into the night, lamps that fit into the laptop that can be used while you’re working on papers, and lamps that are designed for your desk to use for intense work sessions. It’s no surprise they’ve become ubiquitous accessories in bags, on desks and next to beds globally, given that they’re so cheap, low power and in fact so helpful.
