The Mole-Richardson 200W, JuniorLED Fresnel Retro-Kit includes a MoleLED Daylite trough, a MoleLED specific fresnel lens, and a hardware package with tool. This retrofit kit helps to keep the Mole-Richardson Fresnels (sold separately) working for another generation. This self-contained trough allows you to convert your existing Daylite Fresnels to a Daylite LED with no modifications needed to the head. You can keep your original Daylite trough for future use, and switch between the two in minutes should the need arise.
