Hi Nick, its a fair point, but you should remember that stryker don't have a lamp manufacturing arm. In fact most "hardware" manufacturers normally just boil down to 3-4 global lamp manufacturers (Osram, Philips, Ushio, Perkin Elmer). So when these guys need a lamp type to fit a spec on a new machine they will approach 1 of the big 4 to build for them. They then build said product and send to the OEM to put in their branded boxes (the very same lamp PE300B-13FM).
As a little side note, Osram are currently throwing around 20 million Euros a year in to R&D for just LED alone. For that sort of money, it would be next to impossible for an OEM to try to invest enough to develop their consumable on a par with a big lighting manufacturer.
So when Stryker sell this module as a "stryker module" it is manufactured in the same plant with the same components and same staff / QA control as the "perkin elmer" module. Much like the Keymed propoganda, they take the top 3% of quality, in reality it means very little. The QA is so stringent that the top 3% between a 1-100% deviation is so small you can not see any difference under extremely rigorous testing. This is exactly the reason Stryker asked them to build it for them in the first place. This is also why the warranty from Perkin Elmer and Stryker are exactly the same.
So we have to make sure we are talking apples for apples here. Of course, i cant say the same for any other manufacturer who dont originally manufacture them for Stryker. i.e Luxtel for example. It might be just as good but i cant be 100%.
The installation, software(firmware), ibuttons could all cause E1 or E3 errors but unfortunately not the Voltage tolerance on 2 lamps made in the same factory by the same company.
