WHY THE PRICE IS JUSTIFIED

The premium is tied to measurable performance: CRI R1–R15 98.5+, R9 98, TM-30 Rf 98.5/Rg 101, IEEE 1789 flicker compliance, 3,700 lux at 45 cm, DC dimming and two independently rotating bars. Independent inspection praises the all-metal fit and sturdy clamp. No app or prestige-only ornament.

MATERIALS

Body and articulated armsPowder-coated metal alloy

Precise fit, low wobble and useful LED heat spreading; independent inspection found no gaps or looseness.

Light engine96 custom LEDs and 60° optical lenses

Produces 1,800 lm/3,700 lux with exceptional R9 and TM-30 scores while allowing shadow control.

CRITERIA

9/10

Glare Control

Dual bars and 60° lenses let the user shape light and suppress working shadows; diffused output avoids obvious hotspots.

10/10

Flicker Discipline

DC dimming avoids PWM; manufacturer specifies IEEE 1789 flicker-free performance.

9/10

Light Coverage

1,800 lm and 3,700 lux at 45 cm; independently rotating bars spread or concentrate illumination.

10/10

Color Fidelity

CRI R1–R15 98.5+, R9 98, TM-30 Rf 98.5 and Rg 101—best documented spectrum here.

9/10

Mechanical Reach

Sturdy clamp, articulated all-metal arm and independently rotating bars; less general-purpose than BenQ's ball joint.

9/10

Thermal Build

All-metal alloy body and moderate LED drive provide substantial passive heat spreading.

6/10

Controls & Automation

Reliable press/hold DC dimming, but fixed 5000K with no memory, sensor or automation.

IDEAL FOR

·Miniature painting
·Jewelry and electronics benches
·Color-critical illustration
·Precision craft work

NOT FOR

·Warm evening light
·Users wanting automation
·Casual buyers who will not use the color accuracy

DESIGN & ERGONOMICS

Beautifully restrained Swiss industrial design with excellent arm tension and two rotatable bars that can erase shadows. The single-button dimmer is robust but basic; fixed 5000K limits evening ambience.

LONGEVITY

All-metal precision construction, DC electronics and a 2-year warranty suggest a long service life; support exists, but the LED modules are not advertised as user-replaceable.
