Question 1

What is the difference between an LED high bay and a conventional luminaire?

Accepted Answer

An industrial LED high bay typically offers real efficiencies of 130–160 lm/W, compared to the 70–100 lm/W common in metal halides. This translates into consumption reductions of 40% to 60% for the same lux level. Additionally, while a traditional lamp may require replacement every 10,000–15,000 hours, an LED high bay maintains more than 80% of its luminous flux for 50,000 hours (L80), drastically reducing maintenance and installation downtime.

Question 2

How many lumens do I need for an industrial unit?

Accepted Answer

The calculation starts from the required lux level. For example, for a 1,000 m² unit with a target of 300 lux, approximately 300,000 useful lumens are needed on the work plane. Taking into account losses due to height, reflectance, and uniformity (maintenance and utilization factor between 0.5 and 0.7), the actual installation usually requires between 430,000 and 600,000 total installed lumens. This is equivalent, for example, to 10–15 high bays of 40,000 lm depending on the distribution.

Question 3

What height is suitable for installing LED high bays?

Accepted Answer

LED high bays are normally used between 4 and 15 meters, but the selection should be adjusted more precisely: Between 4 and 6 m: 100–150W high bays with 90°–120° optics. Between 6 and 10 m: 150–200W powers with 90° angles. More than 10 m: 200–300W high bays or higher, with 60°–90° optics to concentrate the flux. A poor combination of height and optics can cause losses of up to 30% of the useful flux or generate areas with insufficient lighting.

Question 4

Is it recommended to use regulation in industrial environments?

Accepted Answer

Yes, especially in installations with more than 3,000–4,000 hours of annual use. Systems like DALI or 1-10V allow for additional consumption reductions of 20% to 40% when combined with presence or natural light sensors. In units with skylights, the use of light sensors can maintain constant levels of 300–500 lux by automatically reducing power during daylight hours, optimizing consumption without affecting visibility.

Question 5

What is the useful life of an industrial LED high bay?

Accepted Answer

Most industrial LED high bays are designed for 50,000–100,000 hours (L80–L70), depending on the quality of the driver and the thermal dissipation. In a typical use of 10–12 hours daily, this equates to between 10 and 20 years of operation. In comparison, traditional technologies require several replacements during that same period, increasing maintenance and labor costs.
