Commercial LED Tube Lights
Important factors when using LED tube lights
Numerous luminaires with conventional light sources such as halogen lamps and fluorescent tubes are still being used in industry. The phasing out of these light sources is already in full swing due to EU bans. LEDs have long since conquered the market with their significantly higher efficiency and longevity. LEDs are also free of harmful substances such as the toxic mercury found in fluorescent tubes.
However, the use of LEDs in tube lights does not guarantee energy-efficient and maintenance-free operation across the board. You should therefore take the following factors into account when selecting your LED tube lights:
Caution with LED retrofits
Not all ballasts allow the use of LED tubes. In some cases, considerable modifications to the luminaire are required.
In addition, LED retrofits are usually not designed for operation in a protective tube. The heat build-up in the luminaire body often significantly reduces the service life of the products. This results in frequent bulb changes and, in addition to the associated maintenance costs, every time the tube luminaire is opened, the risk of leakage problems increases.
Flickering and stroboscopic effects
Very basic ballasts can cause the LEDs to flicker. Working under such light can lead to discomfort, headaches and visual disturbances, even though people are not consciously aware of the flickering. In the worst case, rotating or reciprocating machine parts can cause stroboscopic effects with considerable safety risks.
Quality risks of low-cost solutions
Numerous suppliers lure customers with low-cost, low-quality LED tube lights. Their suitability for use in industrial environments should be carefully evaluated. Defects in the thermal management and sealing of the LED tube light often only come to light months later. The cost of repairing or replacing the luminaire outweighs the supposed cost savings.
