I buy the attachment and it trigger my other brighter lamp which work like a charm . the clock 's light , so-called brighter , be a joke . that original clock bulb sometimes come on , and 99 % of the time , do not come on at all . the control to just turn on the light in a dark room mean to touch the second to the bottom right seed size button and hold it till it brighten up . so that be annoying . there be not many choice out there and from what I have see its adequate for I with the attachment . without it , this so call new brighter bulb would not do a thing for I . and I have it right next to my bed . so unless you be face it , how will you know its on ? the term `` bright '' be relative . for I it be - at its brightest - as bright as a candle .
