  • Eye-friendly reading with amber light blocking 99.99% blue light

Lightweight neck reading light

Weighing 125 g and just 1.2 cm thick at the neck, the SingHong book light sits comfortably for long sessions. The soft silicone body and microfiber leather sticker feel skin-friendly and wipe clean easily. It is designed for readers who want hands-free illumination without the bulk of a traditional lamp.

Three colour temperatures with adjustable brightness

Choose from amber at 1800 K, warm white at 3500 K or cool white at 6000 K, each with three brightness levels. Amber light blocks 99.99 % of blue light for bedtime reading, while the cooler settings suit tasks such as knitting or repairs. A single button cycles power and a long press toggles the 30-minute auto-off timer.

USB-C rechargeable with battery indicators

The built-in 1000 mAh polymer lithium cell delivers up to 80 hours of runtime and charges via USB-C. Three indicator lights on the neckband show remaining capacity, with one flashing when a recharge is needed. Check that you have a USB-C cable and a suitable power source before ordering.

Questions about this item

Does the USB-C port charge the 1000mAh battery fast enough for the claimed 80-hour runtime?

The built-in 1000mAh polymer lithium battery charges via the USB-C port and delivers up to 80 hours of use per charge. Three indicator lights on the neck area show the level, and one flashes when the battery is low.

Will the 1.2 cm thick neckband fit my neck without feeling heavy?

The neckband is 1.2 cm thick and weighs 125 g (4.4 oz). Its ergonomic width and soft silicone construction are designed to sit comfortably for long reading sessions.

How do I activate the 30-minute auto-off timer so the light does not stay on if I fall asleep?

Press and hold the power button for more than three seconds to toggle the 30-minute timer on or off. A short press (under three seconds) turns the light on or off normally.
