Projector Lamp Mode Settings Can Have Significant Impact on Lamp Life

Posted by on for ProLampSales

Extending lamp life by smart operator use of features provided in the projector settings, can reduce the frequency of buying replacement lamps  - saving on both the purchase price of the new lamp and the staff time and hassle factor of replacement. 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. However, the projector manufacturers have been just as important in helping extend lamp life with built-in, operator controlled settings that allow modulating brightness to meet...

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...

"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. There are 3 OEM versions: the OEM lamp directly from the bulb manufacturer of the original lamp included with this projector, the same OEM lamp sold by Optoma, and an OEM compatible version from another OEM bulb manufacturer, but not the original manufacturer for this model. We also sell an economically priced compatible...

The Origins and Technology Behind Digital Projection Lamps

Posted by on for ProLampSales

The UHP lamp (ultra high pressure lamp, usually mercury arc) refers to projector lamps with an internal pressure of over 3000 lbs per square inch. The acronym also stands for ultra high performance. Originally developed by Philips in 1995, it is a common light source for digital data front projection, video front projectors and rear projection televisions because it has very high light output available for the small environments of micro display projectors. The main characteristics of UHP lamps designed for most digital projection applications are:- Short arc- Very high luminance- Long lamp life- High luminous efficacy- Precise color spectrum-...

What You Need to Know Before Buying Non-Original Projector Replacement Lamps

Posted by on for ProLampSales

With a glut of non-original lamp modules in the projector replacement lamp market, buyers of these lamps should be aware of potential diminished projector performance issues that may result. According to Philips Lighting, manufacturer of UHP projector lamps, “lamps that are originally installed in a projector are based on co-development activities between the lamp/driver manufacturer and the projector manufacturer”. This co-development helps ensure optimal lamp ignition and brightness performance as well as precisely designed cooling functions to prolong lamp life. In short, original lamp performance depends on the close working relationship between the lamp and projector manufacturers. Here is a...

What does projector ‘rated lamp life’ mean?

Posted by on for ProLampSales

All projector manufacturers work with a select group of lamp manufacturers (Philips, Osram, Ushio, Panasonic, Phoenix) who build the lamps installed in new projectors. Each lamp comes from the manufacturer with a “rated lamp life”, usually between 1500 and 3000 hours. While far from the most important factor in selecting a projector, lamp life should at least be understood, because replacement lamp costs can add up. While the most obvious definition of “lamp life” is it’s operating time, or, the length of time before the lamp goes dark (or begins to flicker). However, another factor in lamp life involves the...

The Epson E-TORL UHE Projector Lamp Advantage

Posted by on for ProLampSales

While most new digital projectors ship with a lamp manufactured by either Philips, Osram Sylvania, Ushio, Phoenix or Panasonic, Epson has forged it's own path with its UHE lamp for Epson projectors. Epson calls their lamp the "Twin Optimized Reflection Lamp or E-TORL". To improve optical efficiency Epson engineers focused on tweaking the reflector of the traditional UHP (Philips), P-VIP (Osram), etc projection lamps. The first change was from the common parabolic reflector to an elliptical shape. The parabolic curvature allows, according to Epson, a significant portion of light to be "reflected away from the light path of the optical...
