When are you sure that you purchase an original projector lamp?

With a large number of the manufacturers of non-original projector lamps resort to misleading information, using false logos and trademarks on their products, it’s very difficult for professional buyers and consumers to buy original projector lamps following a safe and ethical purchasing policy without being misled or deceived.  

Even if the manufacturer has totally no intention to cheat, it’s very difficult for the buyers to distinguish a non-original projector lamp from an original projector lamp.  

Following guidelines can help professional buyers and consumers to learn to see the difference between a good price for an original projector lamp and a potential bad buy.
