Industrial Lighting, Illuminated Signs, and Emergency Safety Signage – 50 Most Frequently Asked Questions and Answers

Industrial Lighting

1. What is industrial lighting?

Industrial lighting is a type of lighting designed for production halls, warehouses, logistics centers, workshops, and industrial facilities. It must meet requirements for high brightness, durability, and energy efficiency. 

2. Why is high-quality industrial lighting important?

Proper lighting increases workplace safety, reduces employee error rates, improves productivity, and minimizes the risk of workplace accidents.

3. What types of lighting fixtures are used in industry?

The most common types are LED high bay lights, linear LED fixtures, dustproof luminaires, and floodlights.

4. Why is LED lighting preferred today?

LED technology offers lower energy consumption, longer lifespan, and lower maintenance costs compared to traditional discharge lamps.

5. What is the lifespan of industrial LED lighting fixtures?

High-quality LED luminaires typically have a lifespan of approximately 50,000 to 100,000 hours.

6. What lighting intensity is suitable for a production hall?

It depends on the type of work performed. Typically, lighting levels range from 200 to 1000 lux according to standards.

7. What does the lux value mean?

Lux is the unit of illuminance, measuring the amount of light falling on a surface.

8. What is the ideal light color for industrial environments?

Neutral white 4000K or cool white 5000K are most commonly used.

9. What is CRI or Ra?

The Color Rendering Index determines how accurately light displays the colors of objects.

10. What IP rating should an industrial lighting fixture have?

For dusty or humid environments, at least IP65 protection is recommended.

11. Can industrial lighting be dimmed?

Yes, modern LED systems support DALI dimming and intelligent lighting control systems.

12. How much energy can LED lighting save?

Compared to older technologies, energy savings can reach 50–80%.

13. What is the difference between high bay and low bay lighting?

High bay lights are designed for ceilings above 6 meters, while low bay fixtures are intended for lower spaces.

14. Is a lighting design project necessary?

Yes, a professional lighting design ensures optimal light intensity and distribution.

15. What standards apply to industrial lighting?

Primarily the EN 12464-1 standard.

16. Can lighting be controlled by sensors?

Yes, motion sensors, daylight sensors, and intelligent control systems are commonly used.

17. What is UGR?

UGR (Unified Glare Rating) indicates the level of glare produced by a lighting fixture.

18. How often should lighting maintenance be performed?

Regular inspections are recommended at least once per year.

19. Are LED fixtures suitable for cold storage warehouses?

Yes, LED technology performs very well even at low temperatures.

20. How do you choose the right lighting fixture?

Factors such as ceiling height, environment, required light intensity, and type of operation must be considered.

Illuminated Signs

21. What are illuminated signs?

They are illuminated informational or safety signs used both indoors and outdoors.

22. Where are illuminated signs used?

In production halls, office buildings, shopping centres, and public spaces.

23. What is the main purpose of illuminated signs?

To improve orientation, safety, and the visibility of important information.

24. What types of illuminated signs exist?

Directional, safety, advertising, warning, and informational signs.

25. Are illuminated signs mandatory?

Some safety and emergency exit signs are required by legislation.

26. What is the difference between a backlit and an illuminated sign?

A backlit sign shines from behind, while an illuminated sign allows light to pass through the graphic.

27. What materials are illuminated signs made from?

Most commonly aluminium, acrylic, and polycarbonate.

28. Are LED illuminated signs energy efficient?

Yes, they have low energy consumption and a long lifespan.

29. Can illuminated signs be used outdoors?

Yes, with the correct IP protection rating.

30. What is the lifespan of an LED illuminated sign?

Typically between 30,000 and 70,000 hours.

31. Is it possible to produce a custom sign?

Yes, most manufacturers offer customised solutions.

32. Do illuminated signs require maintenance

Yes, regular cleaning and power supply inspection are recommended.

33. What type of power supply do illuminated signs use?

Most commonly 230 V or low-voltage LED power supplies.

34. Can signs be equipped with battery backup?

Yes, especially safety and emergency signage.

35. Are illuminated signs visible during a power outage?

Only if they have emergency power or a battery backup.

Emergency Illuminated Signage

36. What is emergency illuminated signage?

It is illuminated safety signage for escape routes and emergency exits.

37. Why is emergency signage important?

It helps people evacuate safely during a power outage or fire.

38. Is emergency signage mandatory?

Yes, in most commercial and industrial buildings.

39. Which standards regulate emergency signage?

Mainly EN 1838 and EN 60598-2-22.

40. What must emergency signage indicate?

Emergency exits, evacuation directions, fire extinguishers, and safety equipment.

41. How long must emergency lighting operate?

Typically at least 1 to 3 hours.

42. What is the difference between emergency lighting and emergency signage?

Lighting illuminates the space, while signage guides people.

43. What types of emergency signage exist?

Maintained, non-maintained, and combined types.

44. What does autotest mean in emergency luminaires?

The luminaire automatically checks the battery and system functionality.

45. How often should emergency lighting be inspected?

Regularly according to legislation, at least monthly and annually.

46. What is the lifespan of batteries in emergency luminaires?

Approximately 3 to 5 years.

47. Can emergency signage use LED technology?

Yes, it is the standard solution today.

48. Where must emergency signs be installed?

Above exits, along escape routes, and at changes of direction.

49. What happens during a power outage?

Emergency luminaires automatically activate using battery power.

50. How do you choose the correct emergency signage?

You should consider the size of the space, legislation, backup duration, and installation method.
