    Product Questions & Answers

    Set Descending Direction
    Does this tilt in more than one directions, ie left / right and also front / back? So it can be precisely angled to a picture centre. Thanks.
    Question by: James Childs on 21 Apr 2022, 16:12
    It tilts on one axis, but you can move the downlight around within the ceiling hole, then adjust the angle of light. This will allow you to precisely angle the beam of light onto the picture centre.

    I'd recommend the more narrow 38 degree beam for this application to provide a more focused beam of light.
