The issue with cheap 3 watt UV LED's is they degrade very quickly do to the UV. Typically 6 months is a good life span.http://m.ebay.com/itm/252431447233?...70&_trksid=p2141725.c100338.m3726&_mwBanner=1
There is a 3w epistar UV diode for less than $2.
Not only do we use true 395nm UV diodes in our fixtures, but they have in organic bodies and silica lenses for longer life. Yes they are more expensive.
