Cambodia School Lighting Project: How One Change Saved 50% on Costs
I: Case Background and Client Needs
1. Project Overview
The end client is a school located in Cambodia, and the engineering contractor is responsible for this project. The total procurement amount for this project is approximately $100,000 (equivalent to $200,000 in local procurement costs), involving lighting renovations in multiple public areas such as teaching buildings, gymnasiums, auditoriums, and warehouses. The school’s goal is to improve lighting quality, reduce energy consumption, and enhance the overall campus environment through this upgrade. The renovation aims not only to create a more comfortable learning and working space for teachers and students but also to significantly reduce long-term operational costs through energy-efficient design, bringing sustainable economic benefits to the school.
2. Client Needs Analysis
The functional characteristics of different areas determine the diversity of their lighting needs:
- Teaching Buildings and Offices: Require lighting with a high color rendering index (CRI ≥90), with color temperature controlled in the cold light range of 5000K-6000K, ensuring even and flicker-free light to reduce visual fatigue during long hours of study or work for students and teachers, while creating a rational and focused atmosphere to enhance learning efficiency.
- Gymnasium: With a ceiling height of 8-9 meters, it requires high-power, high-lumen output lamps to ensure light covers the entire venue, meeting the lighting needs for high-intensity sports (such as basketball and badminton), while considering safety and comfort.
- Auditorium: As a multifunctional venue, the lighting needs to be flexible, supporting various scenarios such as speeches, drama performances, and meetings, requiring lamps with dimming functions and adaptability to different event atmospheres.
- Warehouse (including cold storage): Lamps need to have low-temperature resistance (minimum -50°C), waterproof and moisture-proof (IP65 or above), and explosion-proof performance to adapt to the extreme environment of cold storage, ensuring food safety and long-term stability of the lamps.
3. Special Situation Analysis
The client has strict requirements for delivery time: all lamps must be delivered within 10 days, while the industry standard lead time for lamp production, inspection, and shipment is usually 30 days. As an opportunity for first-time cooperation, we understand that quick response is key to gaining the client’s trust. Therefore, we quickly integrated supply chain resources, optimized production and logistics processes, and ensured high-quality delivery within the tight timeframe. This efficient collaboration not only met the client’s urgent needs but also laid a solid foundation for future long-term cooperation by demonstrating professional capability and execution.
II: Providing a Complete Lighting Design Solution
1. Space Analysis and Functional Planning
We tailored scientific lighting solutions based on the functional characteristics of each area:
- Teaching Buildings and Offices: Selected high color rendering index (CRI ≥90), 5500K cold light LED lamps to ensure bright, even, and flicker-free light, effectively reducing visual fatigue while enhancing student focus and teacher work efficiency.
- Leisure Areas: Used warm color temperature (3000K-4000K) artistic lamps with soft light to create a relaxed and pleasant atmosphere, helping teachers and students relieve study pressure.
- Gymnasium: For the 8-9 meter high ceiling, recommended 100-300W UFO High Bay lamps with high lumen output (150lm/W), strong light penetration, fully illuminating the large space to meet sports needs.
- Auditorium: Designed a flexible lighting system, using dimmable spotlights in the stage area and soft embedded lamps in the audience area to ensure the best lighting effects in different scenarios.
2. Lighting Layout and Illumination Design
In the gymnasium design, the client initially hesitated about the need for high-power lamps. We explained in detail: the gymnasium has a high ceiling and a large area, and ordinary lamps cannot provide sufficient illumination, easily leading to insufficient light or shadow issues. The UFO High Bay lamp is specifically designed for tall spaces, with high light efficiency and excellent heat dissipation, ensuring even light distribution, avoiding glare, and providing a safe and comfortable environment for student sports. This professional advice ultimately gained the client’s approval.
3. Precise Matching of Light Source Types and Color Temperatures
We offer a variety of options in light source selection, with LED being the preferred choice due to its superior performance. In terms of color temperature, we scientifically configure according to the needs of different scenarios:
Colour Temperature Options
- Warm Color Temperature (2700K-4000K): Emits soft yellow or warm white light, suitable for spaces like libraries and restaurants that need a cozy and relaxing atmosphere. For example, in the restaurant area of this project, we selected warm 3500K lighting to make the dining environment more comfortable and pleasant, enhancing the dining experience.
- Cold Color Temperature (5000K-6000K): Presents bright and refreshing white light, suitable for places requiring high concentration and clarity, such as teaching buildings or offices, effectively reducing visual fatigue and improving work and learning efficiency.
- Neutral Color Temperature (4000K-4500K): Combines brightness and comfort, often used in multifunctional spaces to balance practicality and ambiance.

Special Challenges of Warehouse Cold Storage Lighting
In this project, the lighting design for the warehouse area, especially the cold storage part, is particularly noteworthy. The extreme low-temperature environment of cold storage poses strict requirements on lamps, and ordinary lighting lamps expose many deficiencies in this scenario:
- High Energy Consumption and Low Illumination: Ordinary lamps significantly decrease in luminous efficiency in low-temperature environments, consuming more power while failing to provide sufficient brightness, directly affecting the efficiency and safety of warehouse operations.
- Short Lifespan and Frequent Damage: Low temperatures accelerate the aging of lamp materials, and ordinary lamps have poor sealing, prone to air leakage, and even water accumulation and icing inside the lamp due to moisture intrusion, potentially causing short circuits or leakage, increasing maintenance costs and threatening food safety.
- Fragility and Safety Hazards: Ordinary lamps become brittle in low temperatures, prone to cracking or bursting, with high damage rates, further increasing replacement frequency and operational interruption risks.
