Jacobs University plans to switch to LED technology
In this context, the university currently tests the driverless LED tubes from vendor GT BiomeScilt, also based in Bremen. In January, this company has introduced a driverless LED module product family which can be connected directly to AC mains.
Within the scope of the trial, the university replaced 114 conventional fluorescent tubes in the Research IV building. Before the researchers selected the BiomeScilt product for their test, they already performed a pre-selection process in which light intensity and heat generation were decisive factors. According to postgraduate Claudius Hardt who oversees the tests, the BiomeScilt LED tube is "only the second product that convinced us".
The test results show that the BiomeScilt driverless LED tube features a very even light distribution and a lower temperature level compared to conventional tubes. According to Hardt, the temperature difference is 13°C in favor of the LED product. Since the LED tube is not equipped with a driver, there is no spot where the device can heat up much; for this reason, the likelihood of a failure is lower.
Another significant parameter, the variation of the light intensity over time, has yet to be determined. In any case, the power saving effect will be very significant. While a conventional CFL tube features a power consumption of 78 watts, comparable LED-based luminaires achieve the same effect with only 24 watts. The Jacobs University expects a savings effect of up to 1 million kilowatt-hours per year if they shift to LED lighting. While the price of LED luminaires is still significantly higher than the price of CFL tubes, the university expects that the investment will pay out within two years.
