For comfortable bedtime reading, protecting your eyes is essential. A proper bedside wall light should provide soft, stable, and well-directed illumination that supports your vision without disturbing your ability to fall asleep. Here are the key criteria to guide your choice.

Color Temperature: 3000–3500K – the ideal range for nighttime reading

A warm white 3000–3500K offers the perfect balance: gentle enough not to overstimulate, yet neutral enough to render text colors clearly.

• Avoids the dim, yellowish feel of <3000K light.
• Prevents the stimulating effect of >4000K cool white light.

Avoid: fixed cool-white models, as regular exposure before sleep can disrupt circadian rhythm.

Brightness: 150–300 lm, adjustable is a must

Reading requires adaptable brightness, making dimming functionality essential.

• 200–300 lm for clear and effortless reading.
• Below 150 lm to transition smoothly into sleep.

Key Eye-Protection Standards: flicker-free + anti-glare + high CRI

1. Flicker-Free

Choose options labeled “flicker-free” or DC-driven. Test with your phone’s slow-motion mode to ensure no rolling lines appear.

2. Anti-Glare

An effective wall light directs illumination onto the book, not into your eyes. Look for:

• anti-glare diffusers or shields,
• frosted or matte materials,
• a tiltable or directional head.

3. Color Rendering Index (CRI) ≥ 90

A CRI ≥ 90 provides accurate color reproduction and reduces eye strain, particularly when reading illustrated or color-rich publications.

With these considerations, you can create a cozy reading environment that protects your eyes and improves your sleep quality.
