I’m really disappointed, you clam in the website that the light is 60000 lux and i compared it with my colleague light he is using univet eos hd (univet mentioned in there website eos hd is 45000 lux). My lumadent light with full power weaker than his eos hd in half power in all distances. It was really shack for me because it never happened before that American product mentioned fake information in there official website . As well as you mentioned the battery life 40hrs and univet mentioned eos hd battery life time 8hrs but the Reality i end up running out of battery after my one week of using it in duty time while my colleagues that they own univet they only recharge there battery once each 14 days. The light received in box of carton as the YouTube reviewers clam that it came with special box. Totally disappointed and I stopped all my Endodontis friends from buying any lumadent products hard to trust website information. Just last thing the light of lumadent was so comparable to zumax light which the Chinese company of zumax mentioned in there website it’s only 34000lux .
