The major lamp manufacturers - Philips, Osram, Ushio, Panasonic, Iwasaki, Phoenix - have improved the lamp technology such that new lamps can now deliver 4000 hours or more even when operated at full power 100% of the time.

Projector Replacement Lamps: A Quick Guide to Help You Know What Your are Buying

Posted by on for ProLampSales

Projector replacement lamp marketing is a circus of confusion for the customer. Sellers of projector lamps stretch the limits of language to present their lamps in the best possible light.  "Genuine original lamp" "High quality lamp" "Compatible replacement lamp" "Original lamp inside" "OEM compatible" "High quality bulb inside" "Made from original parts" "OEM lamp" "OEM lamp module" "Factory original module" Each of these phrases may accurately describe what the customer is buying. The problem for the customer is that for a given projector model (eg. Epson EH-TW9000) there are several "replacement lamps" that will work for the projector, but each of the options has...

"OEM" - The Smoke and Mirrors of Projector Lamp Module Sales

Posted by on for ProLampSales

The language being used to describe the replacement light source for digital projectors is a case study in sales talk often meant to confuse rather than clarify. Here is an example from the web site of a reseller: “We carry 4 versions of the Optoma EW531 Lamp.

We also sell an economically priced compatible...
