Instead of revealing the exact brightness of these settings, Glocusent describes them as being bright enough for “general reading,” “brighter reading,” and “precise working.” The brighter the setting, the shorter the battery life, and when we tested this light at home, it took more than three days for the battery to die when using a single light in yellow, general reading mode. This dropped to seven hours when both lights were set to the cool white setting, or precise working mode. This battery is rechargeable but note that it will only charge with the cable that comes in the box. Our review model wouldn’t work with any other USB-C line. Do you have enough current? If you’re building a circuit with more than one bulb, you may need another battery.

This book light offers three different brightness levels of low, medium, and high, but unfortunately only offers one color temperature. This color temperature is 6000K, which is my personal least favorite temperature as it is a very bright white…but if this is the color temperature you like, then it can be a good choice for you (many people with issues reading in low light situations find this to be a helpful light). Unlike most of the lights on this list, this light requires you to use it while it is plugged in. You’ll find the on/off and brightness adjuster buttons on a remote attached to the charging cord, and will also find that the cord plugs into a USB port which allows you to charge it from your computer or from a USB wall adapter like the one included with this light. Their updated version of this light offers three color temperatures: vintage yellow, warm white, and cool white. These temperatures range from the low setting of 2700K up to the cool white setting of 6000K, giving you a variety of options and the lowest color temperature on this list next to that of the Hoogalite Amber Reading Light. Colour temperature is measured on the Kelvin scale (K), a numerical scale where warm/yellow light is in the lower numbers and white/blue light is in the higher numbers.READ NEXT: The best air purifiers to buy The best reading lights you can buy in 2023 1.

As I mentioned earlier, this is a highly subjective factor to consider as everyone has different levels of light they like and different levels of light that will work for their situations. But if you at least consider this factor before you buy, then you are much more likely to end up with the best book light for you.

Unfortunately, this light only offers one color temperature. However, this color temperature is 3000K which is considered the ideal night reading color temperature (of course, you may find it’s not the ideal for you depending on your eyesight and your own preferences). For me personally, however, I find this to be an excellent reading color so I don’t mind that it is the only temperature possible on this book light.

But using it by clipping it to a nearby surface is an excellent way to read without having it attached to your book!

In cases like these, I recommend you try to find a light with warm white light as this is not as yellow but still easier on the eyes.
