How We Test

Our testing starts where it matters: at the work surface. We measure what your eyes experience—illuminance, uniformity, flicker behavior, color rendering/accuracy, and ergonomics—then map those results to common tasks and desk constraints.

Lab Setup and Conditions

• Desk Heights and Distances: We test at typical working distances (about forearm length from lamp head to desk) and note the exact geometry for each model. We confirm results on both compact and full‑depth desks.
• Controlled Background: Neutral matte surfaces reduce reflections so measurements reflect the lamp, not the room.
• Repeatability: Instruments are warm‑up calibrated and tests are repeated at multiple dim levels.

Light at the Desk: Lux and Uniformity

• Grid Mapping: We place a grid across the usable desk area and measure lux at each point to create a beam map.
• Targets by Task: We evaluate whether a lamp can reach common targets (e.g., ~300–500 lux for casual screen work; ~750–1,000+ lux for reading/drafting; higher for fine craft) without hot spots.
• Uniformity Metrics: We calculate min/avg and min/max ratios and note falloff toward screen areas to reduce glare.

Flicker and Temporal Light Behavior

• What We Check: Percent flicker, flicker index, modulation frequency, and stability across dimming.
• Why It Matters: Lower risk of eyestrain, better comfort during long sessions, and camera‑safe performance.
• Pass/Flag: We favor high‑frequency modulation or true DC output with negligible visible flicker at all dim levels.

Color Quality and Accuracy

• CRI and R9: We target high CRI (90+) with strong R9 for natural reds and skin tones.
• CCT Accuracy: We verify claimed color temperatures and check consistency across dim levels.
• Consistency: We watch for color shift as you dim or adjust.

Ergonomics and Desk Fit

• Reach and Stability: We measure max reach, joint holding torque, and tip stability so positions hold without drift.
• Controls: We test dimming resolution, memory behavior, and presets (read, screen, craft) for predictability.
• Mounting and Cable Management: We confirm clamp clearance, base footprint, grommet compatibility, and cable routing that plays nicely with monitor arms.

Glare and Screen Friendliness

• Beam Shape: We prefer asymmetric beams that light the desk while sparing monitors.
• Reflection Checks: We place monitors at common angles to observe reflections and haloing, then suggest placement.

Scoring Model

Each lamp receives sub‑scores for: illuminance capability, uniformity, flicker behavior, color quality, dimming/control quality, ergonomics/reach, stability, footprint/fit, build/serviceability, and energy use. We publish how each sub‑score contributes to the overall rating for transparency.

From Data to Recommendations

We translate measurements into task‑specific picks (coding, reading, drawing, crafting) and space‑specific picks (small desks, dual monitors), with beam maps and placement diagrams so you can replicate our results.

Limitations and Updates

We test representative units and note any sample sourcing. Environmental conditions and desk surfaces can influence results; we share our setup so you can contextualize performance. We revisit reviews when manufacturers update drivers, LEDs, or mechanics, and we time‑stamp major changes.
