Laser Blade L has the same concept and construction technology as the original Laser Blade High Contrast, but this new version is bigger and more powerful yet still very compact. It has 5 times the power of the original, despite being only twice as big. And thanks to the optic's construction technology its level of visual comfort remains UGR<19. The glass cover that has been applied to protect the C.o.B. source generates an IP44 rating for the optical assembly.
