I have to wear a bra . I have sensitive nipples and the rubbing from not wearing one burns like a bitch , even from just a day without one . <| sep |> I have the desklamp and really like it . It isn ' t cheap , but it delivers 10000 lux at 17 inches , which few other lamps do and the ones that do are uglier . The delivery distance matters because that ' s how close your face has to be to the lamp to be receiving that therapeutic dose of light . Some of the lamps are only 910 for their delivery distance and I just can ' t put my face that close to a lamp and still read or do anything . I also like that the lamp is made in Canada . I have no affiliation with the company but if anyone is looking to buy , they will have 20 % off on Friday with code BLACK 2016 .
