UV 2021; I did not mention Tims name because i was worried he would get into trouble with the company he works for. I stand behind my previous postings which i copied and will paste it;
When you spend 54k of your hard earned money on new equipment which i did from this company called Tantech in Southern Cal, ((and i allegedly think they go by the name of SunItalia and are located in vegas))
that doesnt work like it should for about 3 years, and you have a frustrating time getting the selling party to make your equipment perform like it should, and s
how very little interest after changing parts twice in the beginning which didnt solve the problem,and having a hard time
getting the company to return your calls 
or even send a tech when THEYare a hour and a half drive, it is a very bad situation for you and your clients. My readings averaged between 60-70 on solarmeters 5.0 at the hp lamp and i had to resort to changing lamps at 150-200hrs. i have not come online about this situation for obvious fear the situation could get worse. The beds were both finally fixed about +/_20 something months. Times change quick and we have huge need for a true 360 hp, so unfortunately i am gonna have to sell the beds now that they are finally working.
I dont know you uv 2021, and i dont expect everyone to believe my experience with TanTech.
