I constructed myself an UV box a few months back, with the help of Loris from APUG. The thing about the bulb is you are looking for a BL365 ( Blacklikght in365 nm wavelength ). The bulb from the amazon says it is for ambient lighting and it is purple. BL365 bulbs produce blue blacklight. It is UV-A light and it is hazardous to stare at them or being exposed to them for long.
This one suits your needs. Look for the wavelength, BL365
Regular light bulbs are E27 socket and I don't think you can blow it up buy using these bulbs. They are usually 20W bulbs, but check your current bulbs Watt in the light box to make sure.
BTW mosquito trap bulbs might work too. They are BL350.
