4.5 W LED desk lamp with dual USB charging

The DNBeffulgent O'Bright Astrum delivers 450 lumens of 3000 K warm white light while drawing only 4.5 watts. Its built-in Type-C and USB 2.0 ports supply up to 10 watts for phones or tablets. The 270 degree swivel arms let you direct light exactly where you need it for reading or office work.

Sustained output with minimal heat

The 4.5 watt LED runs continuously without the heat buildup common in higher-wattage fixtures. Energy consumption drops by roughly 80 percent compared with incandescent equivalents, so the lamp stays cool during long evening sessions. The push-button switch on the base provides instant on-off control without standby draw.

All-metal construction and fixed cable

The shade, arms and base are 100 percent metal finished in black metallic, weighing 2.059 kilograms for a stable footprint. The mechanical rocker switch adds tactile feedback and a vintage aesthetic. Because the unit is not water resistant, it suits dry indoor desks and bedside tables only.
