Different types of High Bay fixtures
High Bay lighting is available in various forms, each with specific features to meet different needs and aesthetic preferences. The most common types are the round UFO High Bays and the linear High Bays.
Round UFO High Bay lights
UFO High Bay lights are characterized by their compact, round, and often flat design, reminiscent of a UFO's shape. This popular variant typically features a wide beam angle, resulting in uniform light distribution over a large area. This type is often chosen for general lighting in open spaces such as warehouses and production halls.
Linear High Bay lights
Linear High Bay lights have an elongated, rectangular shape. These fixtures are particularly suitable for illuminating aisles or specific zones where more directed light distribution is desired, such as between shelving in a warehouse. They can be mounted on the ceiling or suspended as pendants.
Important technical aspects of High Bay lights
When choosing High Bay lighting, several technical specifications are important to find the right lighting solution for your space. Understanding these terms helps in selecting the most suitable fixture.
| Specification | Explanation | Relevance for High Bays |
|---|---|---|
| Lumen (lm) | Unit for the total amount of visible light emitted by a source. | Indicates how bright the light is. Higher lumen values are necessary for high ceilings. |
| Colour temperature (Kelvin) | Indicates the 'colour' of the light, from warm white to cool white. | Cool temperatures (4000K-6500K) are more common in industrial environments for a bright, activating work atmosphere. |
| CRI (Colour Rendering Index) | Measures the degree to which a light source renders colours faithfully. | A high CRI (80+) is desirable in environments where colour recognition is important, such as workshops or showrooms. |
| IP rating (Ingress Protection) | Indicates the protection against dust and water. The first digit stands for dust, the second for water. | For industrial and damp environments, a higher IP rating (e.g., IP65) is important. |
| IK rating (Impact Protection) | Indicates the impact resistance of a fixture. | Important in environments where the light may be exposed to mechanical impact. |
| Beam angle (degrees) | The angle at which light is dispersed from the fixture. | A wide angle (120°) is suitable for open spaces, a narrower one (60°/90°) for high aisles. |
Recommended wattages for High Bay lighting
The required wattage for a High Bay light depends on the ceiling height and the desired brightness on the work floor. Below is a general guideline for LED High Bay lights:
| Ceiling height | Recommended wattage (LED) | Comparable to traditional |
|---|---|---|
| 4 - 6 meters | 50 - 100 Watt | Up to 250 Watt Gas Discharge |
| 6 - 8 meters | 100 - 150 Watt | 250 - 400 Watt Gas Discharge |
| 8 - 12 meters | 150 - 200 Watt | 400 - 500 Watt Gas Discharge |
| More than 12 meters | 200 Watt or more | 500 Watt or more Gas Discharge |

Installation and placement of High Bay fixtures
High Bay fixtures are usually suspended from the ceiling using chains, cables, or brackets. Correct installation ensures optimal light distribution and safety.
- Mounting via eye or hook: Many UFO High Bays are equipped with a mounting eye on top, to which the light can be attached to a structure with a chain or steel cable.
- Mounting bracket: Linear High Bays and some UFO models can come with a U-shaped mounting bracket, which can be screwed directly to the ceiling or a wall. This offers flexibility in the light angle.
- Safe connection: Always ensure a safe electrical connection and turn off the power before starting the installation. If in doubt, consult a qualified electrician.

Smart features for advanced lighting
Modern High Bay lights often offer smart functionalities that further increase energy efficiency and ease of use.
- Dimmability: Many LED High Bays are dimmable (e.g., via 1-10V or DALI), which allows the light intensity to be adjusted to the activity or daylight level, resulting in additional energy savings.
- Integrated sensors: Fixtures with motion or daylight sensors automatically switch the lighting on or adjust the brightness based on presence or the amount of natural light. This significantly reduces unnecessary energy consumption.
