Choosing this model
GL450BKB selection guide
Choose GL450BKB when the installation calls for wall mounting. GL450XTS1 is the ceiling-mount alternative, so mounting position should be settled before comparing gain or physical dimensions.
GL450BKB includes horizontal and vertical beamwidth specifications that can be checked against the required pointing direction. If a nut-fixed ceiling installation is required instead, assess GL450XTS1 on its own mounting and size data rather than treating it as a wall-mount substitute.
