By Spinea, s.r.o. we were approached with a demand for a suitable replacement of traditional 400W discharge lamps in their production halls. In addition to the expected savings in operating costs, the client also demanded an increase in lighting comfort at workplaces. We were happy to provide the client with our luminaires for free tests and comparison with the competition. We are not afraid of comparisons and tests. It is ideal if the client can verify the declared technical parameters of the luminaires also in real tests and comparisons with the competition. Measurement of lighting technical parameters, above-standard economy, but also the acceptance and preferences of the company's production staff brought the client's decision in favor of our luminaires. We thank our clients for their trust and wish SPINEA many satisfied customers from all over the world.
