Core Eye-Protection Technology
Sanjiayi Lighting continuously invests in optical R&D, using scientific methods to safeguard the health and quality of every beam of light.
Simulates natural sunlight spectrum, reduces harmful blue light, and restores true-to-life colors.
Equipped with full-spectrum LED chips that mimic natural sunlight, this design reduces harmful blue light in the 415-455nm range while maintaining a high Color Rendering Index of Ra>95 for true-to-life color accuracy.
DC constant current power supply eliminates flicker for comfortable, extended use.
Built-in constant-current driver circuit with output current fluctuation below 1%, meeting flicker-free standards. Even during extended reading or work under the light, your eyes remain comfortable and strain-free.
400 0K neutral white light, ideal for extended reading and writing, balancing comfort and focus
Optical experiments confirm that 4000K neutral white light balances visual clarity and comfort. It is softer than high-color-temperature cool white and more conducive to maintaining focus than low-color-temperature warm white.

Trusted and recognized by professional eye care institutions
I bought my child a Sanjiayi eye-protection desk lamp. The multi-head design is very practical, covering both homework and reading. The soft light doesn't strain the eyes, and my child says their eyes feel much more comfortable.
As a teacher, I have high standards for classroom lighting. Sanjiayi's lamp is flicker-free and features full-spectrum light, so students can read without getting tired easily.
The built-in timer is a thoughtful feature that encourages children to take regular breaks while doing homework, fostering healthy eye habits. The lamp's design also appeals to kids' aesthetics.
