It started with a combined goal at Palram: reduce Palram’s carbon footprint, while also reducing operating expenses. Palram has completed the process of swapping out all its low efficiency metal halide lighting for the higher efficiency T5 lighting. Motion sensing detectors were also installed in some areas for even greater energy usage reductions.
The T5 lighting has a shorter start up time and a 20% longer life than metal halide lighting. The long life of the T5 lighting will allow for reduction in maintenance and lamp replacement costs. The initial start up and restart time of the T5 lighting is less than 1.5 seconds, up to a 160% reduction in start up time and up to a 400% reduction in restart up time versus the metal halide lighting. The faster restart of the T5 lights also adds safety value in the production halls and warehouses during power outages.
The new T5 lighting also produces a higher and more consistent lumen per watt output value versus the metal halide lighting. The T5 lights start bright and stay bright while the metal halides will fade significantly over time. In addition, T5 lights have a greater Color Rendition Index (CRI). The CRI is the ability of a light source to mimic natural light when viewing colors. This helps to reduce the effect of metamerism, specifically illuminant metameric failure, where colors will appear differently in different sources of light. Natural light is the best source for color comparisons. With the addition of the T5 lighting, Palram has increased the production area CRI by 40%, which is excellent news for color production monitoring and observation.
