I wanted the lamp actually give a medical student as pupillary reflex lamp, and have let me convince you of the great reviews, unfortunately I have to review, in which states that the lamp is not admitted as pupils lamp is not read. In the other reviews much it was reported that they functioned as great as pupils lamp that I would not have thought so, since there would be a problem. Perhaps you could add them to the item description that it is suitable as pupils lamp fails because it overlooked significantly, many customers either pointing backwards on the package or it simply does not care whether it is allowed or not. Otherwise, the lamp makes a decent and stable impression.
