Aggregate ratings lean positive, with most ratings in the four- or five-star categories, but a smaller share is two- or three-star. With no written customer feedback supplied, the ratings do not establish what buyers liked or disliked. For buyers considering the stated 38 × 16-inch format and adjustable controls, the ratings alone cannot confirm coverage or light-output performance.
