Read anywhere. Day or night. The Xteink Magnetic Reading Light is the official lighting solution for the X4 eReader — the accessory that removes the X4's one practical limitation and extends its usability into every lighting condition, including the dim evening environments and nighttime reading scenarios where the X4's E Ink display without a front light cannot function.

The X4 was designed without a built-in front light in order to achieve its 4.9mm profile and paper-like display clarity — a deliberate design trade-off that delivers an exceptional reading experience in good light but leaves the device dark in low-light conditions. The Magnetic Reading Light is Xteink's purpose-built solution: a compact light that snaps directly to the X4's built-in magnetic ring, positions over the display, and illuminates the E Ink screen evenly without the harshness of a phone or tablet backlight.

The magnetic attachment is what makes this light designed for the X4 rather than a generic clip-on alternative. It snaps onto the X4's magnetic back and holds position without a clip, bracket, or readjustment every time you pick up the device. Detach it when you don't need it — in natural daylight, or when carrying the X4 attached to your phone — and snap it back in a second when you do. The same one-motion interaction philosophy that defines the X4's entire accessory ecosystem.

For X4 owners who read in bed, on evening commutes, in dimly lit cafés, during flights, or anywhere that natural light is insufficient, the Magnetic Reading Light converts the X4 from a daylight-only device into a fully capable any-condition reader. It is the accessory that completes the X4.
