How does an ellipsoidal light work?
An ellipsoidal reflector spotlight features a built-in reflector in the shape of half an ellipse. By positioning the source light within the ellipse, rays of light emanating from the source are bounced off the surface and reflected to a single point, called the conjugate focal point (CFP).
What do the different degree angles do for a Leko light?
A Leko lens is measured in degrees. These degrees measure the degree of refraction that determine how wide or narrow the light is dispersed. A 19 degree lens will have a narrow dispersion of light, compared to a 50 degree lens. And theoretically, that 19 degree will be much brighter than the 50.
