Fear seems to be the default these days . I wish people would keep up better guards . I ' ve seen people so deep in fear , so captive , and into that fear they wish to bring others .

How much UV is too much UV ? It is a difficult question to answer the best answer is to try and avoid it as much as you reasonably can . You can read up more on the potential dangers yourself . I believe the Convoy S 2 UV runs 2 x 7135 , meaning you run the UV led at 23 W many aspects ignored that is a decent amount of UV . Always be a bit cautious with it never shine it into eyes , avoid reflective surfaces and wear glasses . A quick burst without glasses for checking something every now and then I personally think has very limited dangers . But I do try to avoid it . edit also I believe PC only blocks up to about 380 nm , but wavelenghts up to 400 ' ish nm i believe can be a bit harmful too . Therefore the convoy UV filterfilterfor 365 nmlight 330416 tel 5 . html is a really great idea . edit 2 did read up a bit more on it . Found these guysuvledsreallydangerous discussing it . Note table . Assuming the LED emits 3 W UV OTF , and you light up 1 sq meter surface that reflectsscatters the UV back , they claim that the daily exposure should not exceed 10 seconds . I can ' t acces the report they refer to , and there might be many details missing , and I might understand the chart wrong but this estimate matches decently to my expectations .
