Hi. My eBay-Fu powers seem to have disappeared. Even though I hound it multiple times earlier today on a foreign eBay site but I can find it no more. Very frustrating. The light was listed as being compatible with the Hanvon N520. It was one of the USB lights on a stiff bendable cable so you can bend it to give a comfortable Reading light. I guess any led light would work but there is most likely current limitations so perhaps best not to try
