📋 目次
1What lumen range is best for reading in low light?
Aim for 100-200 lumens for most book lights — enough to illuminate a page without glare. Lower than 80 lumens may strain your eyes, while higher outputs are better for larger books or darker environments like tents or campers.
2Should I choose warm or cool white light for reading comfort?
Warm white (2700K-3000K) is easier on the eyes for long reading sessions and mimics natural candle or lamp light. Cool white (4000K-5000K) offers brighter, daylight-like illumination, which is better for detailed work but may cause eye fatigue over time.
3How important is USB power compatibility for a book light?
USB-powered lamps are convenient and widely compatible with laptops, power banks, and wall adapters. Look for models that support USB-C or standard USB-A for flexibility, and check if they draw more than 500mA to avoid draining your device too quickly.
4What’s the benefit of adjustable brightness and angle?
Adjustable brightness lets you match the light to your environment, saving battery and reducing eye strain. A flexible neck or swivel head helps direct light precisely on the page, not your face, and is especially useful for reading in bed or on the go.
5Are LED or traditional bulbs better for a USB book light?
LED is the clear choice for USB book lights — they’re energy-efficient, long-lasting, and produce little heat. Traditional bulbs are bulkier, consume more power, and are rarely used in modern portable lamps due to their short lifespan and higher energy use.
