Fake/ Counterfeit Lamps

Fake/Counterfeit Lamps

The sale of fake projector lamps is increasing & has infiltrated legitimate markets in every country of the world. Many resellers are unwittingly buying & selling fakes without realising it because their reputable supplier has been similarly duped by their supply chain.

Are you buying counterfeit? 

Spotting a Fake

Counterfeit lamps aren’t always easy to spot & often you need to have an original lamp in its box together with the fake to start to see the anomalies in cage design & manufacture, box construction, labels and general printing. 

However, the majority of counterfeit lamps can be identified. Philips bulb made for Benq and Philips bulb made for After Market, we know this because the 55 underlined in red is the marking Philips put on the bulb for Benq. If you buy a manufacturers original replacement lamp it will also have a Philips bulb with the number 55 on it. Then there is the the bulb was made by Philips for the aftermarket with the ‘AM’ code & you would expect to see this on a Diamond Lamp or other ‘Genuine Inside’ lamp but not on a manufacturer’s original lamp. If you bought a manufacturer's original lamp for this model & don’t see a Philips bulb, got a Philips bulb with a different two digit number then you have probably been sold a counterfeit lamp.

From 3M to Zenith there are approximately 200 different projector brands known as Original Equipment Manufacturers (OEM) and nearly all of them buy their bulbs from a 3rd party. Even huge manufacturers like Sony, NEC, Samsung and Dell.

The bulbs are supplied by a select group of specialist lighting manufacturers that include household names such as Philips, Osram and Ushio. However, as well as making for the projector brands they also make bulbs for aftermarket customers such as Diamond Lamps. These latter customers buy bulbs that are identical in performance to the OEM bulbs but are intended to be packaged in their own branded boxes using cages they have developed for themselves as an alternative lamp to the OEM at a similar performance but at a lower price.

Issue #1 Some aftermarket competitors to Diamond Lamps are producing their alternative lamps & then making replica boxes identical to those from Sony or NEC for example then selling it as a Sony or NEC lamp. Not only are they defrauding the original projector brand and breaking the law, but they are duping the resellers & their customers out of money by charging a much higher price than they would for their correctly boxed lamp.

Issue #2 Other manufacturers of counterfeit lamps go for the cheapest solution possible & will fit any old bulb into a lamp they think will work, including second hand. Examples encompass counterfeit bulbs & compatible bulbs that give lower brightness & have a shorter lifetime. They can even be a fire risk.

If you are being offered a lamp that is substantially cheaper than any of their competitors then you are in all probability not being offered a genuine replacement lamp.

There are seven companies that manufacture bulbs for the dozens of projector brands, each has a way of marking their bulbs and those that sell to the aftermarket mark them differently.

Manufacturers for OEM and After-Market (OEM – original equipment manufacturer)

Philips are the largest bulb manufacturer & pioneered the technology.

Philips identify their bulbs with a code, the code will start with the letters HSCR, MSCR or MSFR and the replacement lamp should have the identical marking.

Can’t see the bulb markings?

In roughly 50% of lamps the bulb markings are clearly visible, but some lamps either have the bulb orientated so you couldn’t read the markings without a dentist’s mirror. If the bulb orientation differs we would be suspicious as this is a rare practice and has been used to hide the markings from casual inspection.

Beyond the bulb markings there are other ways to either identify a counterfeit lamp that are either conclusive or by the weight of evidence make you feel that you have a fake.
