Versatile Clip-On Lamp for Multiple Uses

This ReinHoo QYJC01-A swing arm lamp provides adjustable lighting for reading, desk work, and bedside use. Its clamp design attaches to headboards, tables, and shelves without permanent installation. The 360° adjustable arm allows precise positioning for any task. It suits home offices, bedrooms, and study areas needing flexible illumination.

550 Lumens at 5.5 Watts with High Colour Rendering

The lamp delivers 550 lumens of brightness while consuming 5.5 watts through 56 LED beads. It achieves a colour rendering index of Ra90, surpassing typical Ra85 alternatives for more vivid colours. The full-spectrum LEDs operate without flicker, glare, or blue light emission. This specification protects eyes during extended reading or work sessions.

50 Lighting Modes with Memory Function

Five colour temperatures from 3000K to 6000K each offer ten brightness levels, creating fifty distinct settings. The memory function recalls the last used mode when the lamp stays powered on. USB power input enables connection to adapters, power banks, or computer ports. The metal construction in black finish measures 4.33 by 3.5 by 20.71 inches.

Questions about this item

How bright is 550 lumens when the lamp is clipped to a headboard?

The 550 lumen output from 56 LED beads provides strong, focused light for reading in bed without disturbing a partner, and the Ra90 colour rendering keeps text and colours looking natural.

What does the USB power adapter limit in practice?

The lamp draws 5.5 watts over USB, so it runs from any standard 5 V charger or computer port without needing a dedicated mains plug.

How thick a surface can the clamp grip and still allow the 360° arm to move freely?

The clamp fits headboards, desk edges or shelves up to its maximum jaw opening, and the 20.71 inch gooseneck rotates 360° at the base and bends along its full length for precise positioning.
