Leaf Biophilic LED Table Lamp

Biomorphic Design with Precision Engineering

The Leaf Table Lamp merges organic, nature-inspired form with precision-engineered lighting performance. The curved stem, modeled after a growing plant stem with two decorative leaf elements, is formed from 16-gauge steel through a CNC tube-bending process with radius tolerance within +/- 0.5mm. The integrated LED module at the stem tip delivers focused task illumination while consuming a fraction of the energy of conventional incandescent desk lamps.

Technical Specifications

• LED Module: Integrated 5W COB LED, 3000K warm white, CRI 90+, 400 lumens at maximum output
• Optics: Frosted borosilicate glass diffuser (3 inch diameter), 90% transmittance, providing 120-degree beam angle for uniform task illumination
• Stem: 16-gauge (1.5mm wall) cold-rolled steel tube, 0.5 inch diameter, CNC bent to 180mm radius, matte green powder coating (60-80 micron thickness)
• Decorative Leaves: Two laser-cut 18-gauge steel leaf elements (80mm and 60mm length), TIG welded to stem, matching matte green powder coat
• Base: Round zinc alloy die-cast base, 5 inch diameter, 0.75 inch height, 1.5 lbs, white powder coat finish, non-slip silicone pad
• Dimming: Touch-sensitive dimmer on base, stepless adjustment from 5% to 100%, memory function
• Power: USB-C input (5V/2A, 10W), 59-inch braided USB-C cable included; compatible with USB-C PD chargers, laptop ports, and power banks
• Flicker: Constant current driver with PWM > 3000Hz, flicker-free per IEEE 1789-2015
• Dimensions: 16 inches overall height, 5 inch base diameter, 8 inch reach (horizontal)
• Weight: 2.0 lbs total
• Operating Temperature: 32F to 104F (0C to 40C)
• LED Lifespan: 50,000 hours (L70)

Thermal & Structural Performance

The steel stem acts as a passive heat sink, conducting heat away from the LED module through the 0.5-inch diameter steel tube to the base. Measured LED junction temperature at maximum output: 72C ambient 25C, well within the 85C maximum rating for optimal lifespan and color stability. The weighted zinc alloy base provides a low center of gravity (3.5 inches from surface), ensuring stability with the stem extended horizontally; tilt test on 15-degree incline passed without tipping. The powder coating is cured at 180C for 20 minutes and tested per ASTM D3359 (cross-hatch adhesion, rating 4B+).

Construction & Compliance

All steel components are degreased, phosphate-treated, and powder-coated for corrosion resistance. Electrical components UL recognized. FCC certified for electromagnetic compatibility. RoHS compliant. The frosted glass diffuser is thermal-shock resistant (tested per ASTM C149) and provides UV stabilization to prevent yellowing.

USB-C braided cable included. USB power source not included. Integrated LED, non-replaceable.
