Query: Alarming!

I bought this clock from a retailer whose catalog described it as emitting a "gently illuminating light." WRONG!!! Others on this site have described the flashing light very accurately. Gave me the worst migraine I'd had in years. I sent it right back. Too bad, 'cause the design is wonderful, and it would be quite a nice product if it weren't for that quasi-strobe light. I guess it might be okay for light sleepers, but those looking for something to rouse them gradually from a deep sleep should try something else.
