The GloBrite™ Glare Shield (P/N 620314) is for use on GloBrite™ Color and White Underwater lights. The glare-reducing Glare Shield is designed to deflect direct light from the GloBrite LED light lens. Rotate the Glare Shield to the 12 O'clock position for maximum light deflection and increased underwater light. Note: The Glare Shield is recommended for lights installed only on the walls of the pool/spa.
