Every Lumen Counts: Lumen Calculation per Volume and Light Comfort in Conference Halls
A hall with perfect architecture, equipped with a sound system, comfortable seats... But if the light is wrong, it all goes to waste. Because the first element that initiates visual perception in living rooms is light. Readability of the presentation, understanding of facial expressions, increasing attention span and even the prestige of the place are directly related to the lighting design. We answer the questions of how to provide the environment.

🔢 What is Lumen, Luxury What is it?
Lumen (lm) expresses the total amount of visible light emitted by a light source.
Lux (lx) is how much this light falls on a surface of 1 square meter.
So if a bulb gives 1000 lumens of light and this light spreads over an area of 10 square meters, there is 100 lux. It means there is light.

📐 Light per Cubic Meter in Halls Calculation
When making the lighting plan of a hall, not only the floor area but also its volume should be taken into consideration. Because the light is distributed not only on the ground, but throughout the entire space.
A general engineering rule as:
> 🎯 Average lighting need: 200–400 lux
🎯 Hall volume (m³) x 3–5 lumens = total lumens need
Example:
Volume of a hall with dimensions of 10 m x 15 m x 5 m = 750 m³
Ideal lumen in this hall: 750 x 4 = 3000 lumens (minimum value)
However, this value is layered specifically for regions such as stage, audience area and corridor. It should be applied. Light
1. Stage Lighting
Minimum 750–1000 luxury
Spot and projector systems are used to clarify facial expressions white)
2. Audience Seating Area
150–300 luxury
Eye-friendly, homogeneously distributed LED systems
Light color: 3000K (warm white)
3. Corridors and Transition Areas
100–150 luxury
Directional lights integrated with emergency exit warning systems Must be Important
CRI (Color Rendering Index) expresses how accurately the light displays colors. Lights with a CRI value below 80 affect skin tones and facial expressions.
Ideal for conference halls CRI: 90+ should be.
Also, flicker-free LED systems should be preferred. Flickering lights can cause headaches during long sessions, even if unnoticeable. DALI Systems and Scenarios
As Nish Global, we use DALI (Digital Addressable Lighting Interface) based smart lighting systems in many projects. Thanks to these systems:
When the speaker comes on stage, the lights turn on automatically. focuses
Audience area during presentation is dimmed illuminated
Light scenarios according to different types of events can be defined The atmosphere becomes professional. Mistakes
Entire living room with ceiling fixtures alone illuminate
Direct light on the participant's face with spotlights to keep to use
Still preferring halogen systems instead of LED (high heat, low yield)

🔧 Nish Global Approach
We consider lighting not only as "giving light" but as an engineering discipline that defines the meaning of space. In each project:
📊 Light map over the hall volume creates
🔍 CRI, Kelvin and luxury values according to the scenario calculates
🛠️ Control mechanism with integrated systems such as DALI We are setting up
Because for us, a good hall is a hall that is not only heard but also properly illuminated. It is the scene. Conclusion
Proper lighting is as vital as the right sound system in conference halls. Every lumen is a critical investment in the perception of what is being said, maintaining the audience's attention, and the professional appearance of the theater. Remember, good lighting makes it easier not only to see, but also to understand. Warning
