This is a replacement for a velux blind. The gaps round the edges allow more light through than the old blind. There are four \'holes\' in the blind material that allow large pinprick of light through. The action to open and close is not as satisfactory as the old blind. Sorry but a serious drop in quality. Unfortunately there seem to be few options. If I could be bothered I\'d return. But does feel as if velux is taking advantage here. Hope that helps.
