Five reasons why office photos didn't meet expectations

The screens at the workstations were glaring and the text was illegible; the meeting room lights were dim and the PowerPoint presentations were difficult to read; the aisle was bright but the light didn't reach the workstations. The boss was criticized for a month, and finally, they replaced the lights, removed the ceiling, and rewired the system, which took another week.

Office lighting isn't just about installing any light; it's about installing the right kind of lighting for people.

1.Choosing the wrong color temperature is the biggest trap.

           Light comes in different colors:

• 3000K (Warm Light): Yellowish, like home lighting, cozy but can make
  you sleepy.
• 400OK (Neutral Light): Whiter, close to natural light, best suited for
  offices.
• 500OK and above (Cool Light): Bluish, like supermarket or hospital lighting, invigorating but can easily cause fatigue.

      4000K neutral light is preferred for offices

A disastrous installation went wrong: A showroom client had great renderings, but after installation, the lighting was found to be too yellow and dim. The contract only specified "LED lights," but the contractor brought in 3000K warm light, causing everything in the showroom to look off-color. The lights had to be replaced.

2.Color rendering index (Ra) – many people haven't heard of it.

The Color Rendering Index (CRI) refers to the ability of light to reproduce the true colors of an object.

It is rated on a scale of 100. For offices, a CRI ≥ Ra 80 is typically required; for design firms, showrooms, and e-commerce product photography, a Ra ≥ 90 is needed.

Common Problem: A photography client was unable to accurately capture the colors of products in their office. Investigation revealed that the lighting equipment had a CRI of only 70.

How to Avoid This: Clearly specify Ra ≥ 80 in the contract, and Ra ≥ 90 for applications requiring display. Ensure this marking is on the lighting fixture packaging and inspect the materials upon arrival.

3.Only ambient lighting was installed, not task lighting.

There are two types of lighting:

• Ambient light: Ceiling light fixtures that illuminate the entire space.
• Task light: Desk lamps and track lighting that illuminate specific work areas.

Many office projects fail because they only installed ambient lighting.

Workstations are more than two meters above the ceiling, meaning most of the ambient light is attenuated by the time it reaches the desktop.

Example of a problem: In a precision assembly workshop, the ceiling light panel was quite bright, but workers couldn't see the details of the parts, leading to low efficiency and poor quality control. Adding lights to each workstation solved the problem.

How to avoid this: Confirm whether the desktop brightness is sufficient during the design phase and whether additional workstation lights are needed. In open offices, ceiling lights alone are unlikely to be enough.

4.Lighting and fire safety features clash, inspection will fail.

While aesthetically pleasing, recessed spotlights failed a fire safety inspection because they were too close to the sprinkler heads ,posing a risk of overheating and accidentally triggering them.

Regulations require that the distance between light fixtures and sprinkler heads be no less than 30 centimeters, and that they not
obstruct smoke detectors.

Incident Scene: In the office of a catering company, recessed spotlights were evenly distributed on the ceiling. Fire department measurements revealed that several lights were less than 30centimeters from the sprinkler heads. All spotlights had to be removed and reinstalled, and the ceiling had to be replaced; the entire process took more than a week.

Solution: Arrange the locations of sprinkler heads, smoke detectors, and light fixtures uniformly during the design phase, instead of drawing them separately.

5. Several easily overlooked details

• Flicker. Some cheap LED lights flicker, which is not visible to the naked eye, but can be seen by taking a picture with a mobile phone camera; the screen will flicker. Working under such lights for extended periods can easily cause eye fatigue.
• Separate Controls. Separate switches for workstations and aisles, with independent controls for those near windows or further in, saving energy.
• Installation Height. Generally, office lights should be 2.4-2.8 meters above the ground. Too high and the desk won't be bright enough; too low and it will be glaring.
• Emergency Lighting. Must be checked for fire safety regulations; confirm whether it's included in the contract.
• Smart Dimming. Depends on the budget. Not necessary for small companies; for large companies, it depends on the desired atmosphere.

in conclusion：

Lighting may seem insignificant, but employees use it every day. Insufficient brightness, incorrect color temperature, and poor color rendering make employees uncomfortable, inefficient, and prone to fatigue.

Choosing lighting is like choosing a person—the right fit is best.

During the design phase, they bring color temperature samples to the site for testing, observing the effects under natural light at different times of day. Orders are only placed after the final design is approved. They never guess based on drawings. Color temperature, color rendering index, and illuminance are all determined during the design phase and clearly listed in the contract. Changing it after installation requires removing the ceiling and rewiring, which is both expensive and time-consuming.
