Experimental Report on Office Efficiency and Eye Protection Effects of Honeywell H4 Smart Desk Lamp

Experimental Background

This study quantitatively evaluates the H4 smart desk lamp’s efficacy in enhancing office productivity and alleviating visual fatigue under real-world office conditions. The primary focus is validating its adaptive dimming and tri-color temperature adjustment functions.

Basic Information

• Duration: 5 consecutive workdays (9:00 AM–6:00 PM, including breaks)

• Location: Open-plan office space (ambient illuminance: 300–500 lux)

• Participants: 24 office workers (aged 25–40; corrected visual acuity ≥1.0)

• Groups:

  • Experimental Group: 12 participants used H4 (fixed 4000K color temperature + adaptive dimming).

  • Control Group: 12 participants used standard LED desk lamps (fixed 5000K cool white light).

Measurement Tools

1. Work Efficiency:

   • Standardized data entry tests (3 sessions/day).

   • Code debugging tasks (2 tasks/day).

2. Visual Fatigue:

   • JINS Eye Fatigue Scale (0–10 scoring system, Japan).

   • Infrared camera recordings of blink frequency.

3. Device Monitoring:

   • Lux meters for real-time desktop illuminance tracking.

   • H4’s built-in optical sensor data export.

Experimental Procedure

Day 1 (Baseline Testing)

• All participants used their original lighting devices.

• Initial work efficiency and eye fatigue data were recorded.

Days 2–4 (Group Testing)

• Experimental Group: Activated H4’s smart mode:

  • 9:00–11:30 AM: Auto-adjustment (4000–4500K).

  • 1:30–3:00 PM: Locked at 4000K.

  • 3:00–6:00 PM: Restored auto-adjustment.

• Control Group: Maintained fixed 5000K cool white light.

Day 5 (Crossover Validation)

• Device swapping between groups.

• Additional color temperature preference tests (randomized 3000/4000/5000K switching).

  Key Data Comparison

  Metric	Experimental (H4)	Control	Improvement
  Data entry speed	342 words/min	298 words/min	+14.8%
  Code error rate	0.7%	1.5%	–53%
  Midday blink frequency	18 blinks/min	27 blinks/min	–33%
  End-of-day fatigue score	3.2 points	5.8 points	–45%
  Illuminance fluctuation	±23 lux	±158 lux	–85%

  Findings

  1. Dynamic Dimming Advantage:

     • H4 achieved illuminance compensation within 2 seconds when ambient light increased from 300 to 800 lux.

     • 73% reduction in manual brightness adjustments compared to fixed lighting.

  2. Color Temperature Adaptability:

     • 78% of participants preferred 4000K as the primary working color temperature.

     • 5000K was temporarily used only for detailed chart tasks.

  3. Visual Protection Validation:

     • 62% reduction in visual acuity decline for the experimental group.

     • Tear film breakup time (TFBUT) increased by 2.1 seconds (Schirmer test).

This experiment establishes a correlation between the use of the Honeywell H04 and fixed working hours for long-term office personnel, drawing specific conclusions about changes in productivity. The final conclusion indicates that the use of this desk lamp demonstrates significant performance across multiple dimensions of productivity indicators in the evaluation.

 Spectral Tuning for Circadian Rhythm Optimization

Different color temperatures affect melatonin production and alertness levels:

300K (Warm Light): Ideal for evening work, reduces strain

4000K (Neutral Light): Balanced for general office use

5000K (Daylight): Enhances concentration and cognitive function

 Spectral measurements confirm a peak wavelength shift at 480nm, reducing blue-light hazards by 35%.
