Crane Safety Lights – Designed for Customer Applications

Four 140 watt Straits LED crane safety lights mounted on the trolley of an overhead crane in the background. The lights are projecting a red warning box around the crane load

We now have the capability of providing a Safety Crane Light 3D rendering for different customer configurations on a case-by-case basis. The specific renderings are created with reference to customer photographs and incorporate supplied dimensions. The actual renderings are created with lighting design software and our crane light’s IES electronic file.

The benefit of creating a rendering with this method is that it can include variables such as:

  1. Crane light height
  2. Background lighting
  3. Light angles
  4. Surface reflectivity

In addition, it can determine whether the crane load will interfere with the light’s projection.

The graphics are produced with lighting design software (DIALUX) and the crane safety light’s IES file. The IES file was produced by LightLab International who analyzed the crane light’s performance with a goniophotometer; a device that measures the intensity and direction of light emitted from a light source.

The photometric performance data is then entered into a text editor or IES file creation software. This includes the light distribution curve, the intensity of the light at different angles, and other information such as color temperature and color rendering index (CRI).

Thus, accurate results can be created with the 3D software. As a result, our customers can be confident the crane light’s performance will meet their needs.

Below are examples of various safety light configurations and load check for interference. These renderings were all produced with the software and IES file.
