How the 4-in-1 Colour Slider Works
A slider at the back fixes the light at cool, warm or natural white. In 3-colour mode, switching the light off and on quickly moves it between the three shades, so one fitting can suit work, relaxing and everyday use.
Frosted or Clear Diffuser?
The frosted diffuser on the OPTIMA-80 softens glare, which is better for rooms where people sit and look up. The OPTIMA-100 uses a clear diffuser for maximum brightness in shops and workshops.
