I've always wondered why both "sunrise lamps" (like the one you're referring to) and "light-therapy lamps" (i.e. lamps of 10000+lm with a diffuser) exist, but there are no sunrise light-therapy lamps, which 1. go from dim to holy-wow-that's-bright on a slow timer, and 2. which are designed in a shape where you could fit them around your bed somehow. (IMHO, they'd ideally be a flat ceiling panel!)
