Recently, there was a miner lamp tender from a mine of Estonia which our client was bidding for, and our client won it in the past 3 years. However, our client was told that another WISDOM miner lamp provider won the tender with a lower price.

It shocked us, and we immediately concluded that it must be fake WISDOM lamp. The quality of fake miner lamp is poor, and it even may cause a terrible accident, it is our responsibility to stop it. So we let our client show our proof letter to prove we are original manufacturer, and our client won the tender again finally.
