Easylight, developed by CGoutset, is a Blender add-on built to simplify the lighting process. It lets you add IES-ready lights and create, edit, and manage light groups, and it's ready for both the Cycles and Eevee render engines.
The light group system lets you control power, toggle groups on and off, and set color and light temperature across multiple lights at once, with changes applying to every light in the group. Mesh objects using emission materials can be included too. Because the management system is based on Blender's default collection system, you can drag and drop, select, move, or delete lights, and pull in lights that weren't created with EasyLight.
The IES Light Manager lets you add your IES texture library, generate a preview for each file, and apply them in one click, alongside quick-add IES lights and a one-click favorite setup. A frame-based animation system handles group toggle, power, and color settings and is still in development. Easylight runs on Windows only, and IES textures work in Cycles.
