Glocusent Neck Reading Light, Book Light for Reading in Bed at Night, Rechargeable Neck Light Long Lasting Up to 80+ Hrs, 3 Colours & 6 Brightness Levels, Perfect for Avid Readers & Knitters Grey

Product Information

The majority of book lights run on rechargeable batteries. Each one’s battery life depends on a number of factors, from the battery’s size, to the brightness setting you choose and how long you read for. Smaller, basic lights will go from full to flat in a few hours, but more advanced lights can run for more than three days of continuous use. Warm (2700K – 3000K): Bulbs at the lower end of the scale emit a soft white light that often looks yellow. Warm light isn’t the brightest option but is a good choice when you’re in bed, as it’s the most easy on the eyes. Some reading lights take this into consideration and feature multiple settings for different temperature gradients and brightness intensities. Neutral (3100K – 4500K): The middle of the brightness spectrum offers a mix of warm and cool light, and is the most versatile temperature. 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.

Clip-On Light: The clip-on book light requires more lumens.Because they generally have bigger sizes and heavier weights. Hence, consumers usually use clip-on book lights as fixed bed reading lamps or a reading light clipping on the bed headboard. For a well-designed clip-on book light, reaching more than 150 lumens is a common practice to light up the entire bedroom, not only for book reading.The best book lights offer multiple color and brightness settings. This is so you can customize your lighting to suit your eyesight preferences.

Construction: From metal to plastic, book lights are made of many different materials. Consider durability and whether each book light will work with the type of books that you read. The light angle is only 90-degree, illuminates in a narrow beam. So it only lights up the area you positioned and it is dim enough to other passengers. Other than that, you can also adjust the brightness to the dimmest level. The two arms feature LEDs that provide either 2,700K of warm white light, which is suitable for reading, or 7,000K of cold white light, which is great for more precise working. There are then three brightness levels: spotlight, floodlight, and spot/floodlight combined. Its rechargeable battery lasts up to 16 hours on the spotlight setting, and you can charge it via standard USB. While most of us might use this light to read on the sofa, in bed, or on public transport, you could think out of the box and take this on a dog walk, an evening jog, or to focus better on DIY and craft projects that need illuminating. The light comes in three colours and has a built-in lithium battery that’s recharged via a provided USB cable. It takes about 2.5 hours to reach full charge, and then should last for 16 hours at normal brightness or 6.8 hours at the highest brightness level.Book Light for Kids: Children are commonly perceptive to strong lights when reading, especially using a book reading light due to some reading before sleep. Therefore, the light has to be soft, gentle, and eye-caring for kids. 15 lumens are preferable when choosing a book reading light for kids when reading before bed.

Lumen and watt measure different things for sure. Watts refers to how much energy the light bulb uses, while lumen indicates the light bulb's brightness or the light output of a light bulb. Watts do not tell you how bright the bulb is, but lumens do. Lumen measures the total quantity of visible light emitted by a source per unit of time. Lumens are now a new way of knowing how bright a lamp or a book reading light is. The brightness level of a book light associates closely with the lumen. You might need different book lights in various reading environments depending on your needs.While choosing the right book light, you would need to consider certain factors including brightness levels, the comfort of usage, portability, charging options, battery power, style, and cost. This bedside book light plugs mimics the soft, warm light emitted from candlelight. It has three brightness settings—25, 50, and 100 percent—so you can make it as bright as you need for reading. It also has a flexible arm that lets you direct the beam of light at the best possible angle, which increases how much of a book you can see at one time. The lamp is rechargeable using the included USB cord, and it can last for up to 16 hours. Color temperatures are measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. When it comes to book lights “there are two main ranges of temperatures,” explains Sunir Garg, MD, clinical spokesperson for the American Academy of Ophthalmology. “One temperature is around 2,700K. This is similar to what a traditional incandescent bulb emits and is considered ‘warm.' The other range is around 5,000K.This is a typical white light or ‘daylight.'" The light head can be swiveled and rotated by up to 270 degrees, so you can point it at your sweater or your book whilst knitting or reading. Additionally, you can prop the LALAKU LED light on a flat surface and use it as a makeshift table lamp, too. Amber Book Light: As for the amber light, 20 lumens are commonly preferred. The soft and gentle amber light will stimulate your body to produce more melatonin naturally. It is widely used for reading in bed before sleep with the special amber mode.
