A summer evening, in the garden: gazing at the moon through dense foliage. It is the Twice as Twiggy Grid effect: a circle of light seems to float in the air, trapped in the diffuser screen that contains it. Twice as Twiggy Grid is a Twiggy whose volume has more than doubled. Now, for outdoor use, it has a shade in a woven composite material: this helps it to stand up to wind, and filters the beam from the light source.
