At Light4U BV, one of our core missions is to continually improve and upgrade existing products, delivering enhanced performance, efficiency, and comfort to your lighting projects. We are proud to announce that the popular Forsite linear lighting series has received a significant upgrade, focusing on three key improvements:
- Higher luminous flux up to 10700Lm
- Improved efficiency up to 162Lm/W
- Better visual comfort UGR<19 is now available in more versions
With the new lenses and PCBs, CRI80 versions will be phased out in favour of the higher-performing system. This means that performance gains compared to CRI80 are between 10% and 24%, and compared to CRI90, between 32% and 49%. Furthermore, another advantage of the new configuration is that for beams up to 60°, the UGR remains below 19. For the lowest power versions (25W and 33W), UGR is below 16. This makes Forsite suitable for offices, general work, and CAD environments.
