Our specimens of the functional lights with frosted glass reflector were designed for use in schools and offices. Rounded off at the top, the luminaire offers no storage space for dust. With its shape and glass quality, the stepped glass body ensures optimal diffusion and glare-free lighting. This model combines the effect of partially frosted glass and clear glass in one glass body. The luminaires of the SISTRAH luminaire from Stuttgart, which was known for glare-free light, are formally reproduced. All lamps are rewired.
