Q: Why there are 2 different LED wavelength 260-280 nm and 320-430 nm ?

Because the lights in the wavelength of UVC in 260-280 nm is transparent and invisible, for human seeing, so added the 320-430 nm wavelength, so that we can see the LED works or not.

Q: Do you have to flip items over?

No you do not need to flip the items. There is a light at the top and the bottom.

Q: What are the interior dimensions?

Approximately 10 inches lengthwise by 7.5 or inches wide by 4 inches deep. The entire thing is soft walled, not rigid. It can be squashed down flat for storing. There is also a non-attached metal rack provided to help lift items being sanitized so the light can reach the underside.
