An integral part of downlights, our Castor series is a popular LED lamp which has an unmatched heat-sink structure. Complete this LED module by pairing it with our Argo reflector series for a well-lit ambience. Available in all black, all white and a classic pairing of black and gold, these reflectors easily morph across architectures. Combining the efficiency of high lamp life with dimmable and undimmable features, these architectural lights can be a great way to flood your lounge or dining space with mood lighting.
