Photocell Light Shield

This photocell light shield was created to slip over any type of round photocell. See below link for the photocell that I designed it for. This photocell has a 16 mm outer diameter so the inner diameter of the light shield is 16 mm. This device will help block the light from the light fixture it is controlling to prevent nuisance on/off switching.
