The WindowLED project is centered around DIY. People retrofitting or creating lamps, and tinkering with changes. People share what they do in forums. Anyone can offer anyone’s products in stores. Ultimately, the community can decide which projects can be displayed on the DIY page.
Here are some early videos of the First Beta WindowLED, to help get this project started. The videos only show retrofitting with the assemblies and the kit, which are very expensive, but you can build your own from raw parts for around $180. Check out the store for assembled parts, or links to the raw parts you can buy online. The lamp and components or parts can be created or purchased in the store or elsewhere online.
