2. Advanced Nail Curing Technology & Design

Sparkling Rhinestone Diamond Design

The distinctive SUN L4 features a decorative crescent-shaped panel surrounding its central digital display.

The sparkling diamond-inspired finish, ornamental floral patterns, and smooth curved body combine practical nail-care functionality with an attractive appearance.

This makes it particularly appealing to customers who prefer stylish beauty equipment rather than ordinary nail lamps.

24 UV LED Light Beads

The lamp incorporates 24 UV LED beads to deliver light for curing compatible gel nail polish.

The LEDs illuminate the curing chamber while the open-front design allows convenient finger positioning.

Actual curing performance depends on the lamp's wavelength, energy output, gel formulation, and exposure duration.

Infrared Automatic Hand Detection

The SUN L4 incorporates intelligent infrared sensing for convenient hands-free operation.

Hand Inside — Light ON: The curing light automatically activates when the sensor detects a hand inside the lamp.

Hand Removed — Light OFF: The light switches off when the hand is withdrawn.

This feature reduces unnecessary button pressing during manicure sessions.

Three Timer Controls & Digital Display

The upper control panel contains three physical buttons below the central digital display.

These controls allow selection of timer settings, while the display provides visual information about the curing cycle.

The exact timer durations must be confirmed from the SUN L4 operating instructions.

Bottomless USB-Powered Design

The SUN L4 has an open-bottom construction without a removable or fixed baseplate.

This design allows convenient positioning over a hand or suitable flat surface.

The lamp is powered through a USB cable and does not require battery charging.
