Astera's Wallwash Diffuser

Many customers are intrigued by the X-Series wallwashers. We have wallwasher diffusers for our AX3 Lightdrop™, AX7 SpotLite™, and the AX10 SpotMax™.


With the X-Series having a wallwash diffuser, it replaces the need for a fixture dedicated to solely wallwashing (an AL6-M, for example). Adding the wallwash diffuser (AX3-WWDSK) to an AX3 Lightdrop™ instantly transforms it from a spotlight into a wallwasher, and it really does wash a whole wall with colour (much more than the AL6-S or AL6-M can achieve, see below).

Just by adding a plastic diffuser, the AX3 Lightdrop™ produces a nice even wash of light, compared to the AL6-S or AL6-M which has a floor-facing arc and only illuminates vertically. The 17° x 46° elliptical diffuser makes the X-Series a much more viable option for wall lighting because not only does it produce a desirable effect, but there are multiple other uses to the lights. The AL6-M is almost twice as expensive as the AX3 and the illumination is much worse.

The wallwash diffuser is an elliptical plastic sheet. Up close you will see that the diffuser has a grid-like effect, which allows the light to evenly pass through and illuminate a wider area, as opposed to the direct vertical beam of traditional wallwashers. As you can see below (AX3 Lightdrop with a wallwash diffuser), if you turn the light, the direction of the beam will be tilted.

So when this is used as an up-lighter, the light is horizontally longer, and therefore spreads more effectively over the surface of a wall etc. 

Tip: To wallwash; rotate the diffuser so it emits light as in the top left image, but to light up columns; rotate the diffuser so it emits light as in the bottom right image. This highlights an additional benefit that traditional wallwashers cannot possibly achieve.
