New Year, New JVC Research

Tuesday, February 3rd, 2009

A recent light intensity study by finds that buying generic lamps for JVC will create noticeably dimmer pictures than an OEM or recommended replacement product.

JVC TS-CL110UAA OEM vs Generic

Thursday, November 20th, 2008

Recently, we found many dealers online purportedly selling OEM product, but shipping generic. We decided to purchase one through a proxy and see for ourselves.

The part they advertise is a “GENUINE ORIGINAL LAMP & HOUSING,” however “Bulb pictured may not represent description, please ensure you are ordering the correct model. Do not hesitate to contact our sales staff if you have any questions.”

We decided to call–just to be sure.

To paraphrase our conversation with the nice gentleman, he stated that it is an original OEM lamp made by Philips. According to our research, Philips has only recently become the OEM for JVC televisions, and the actual OEM is Matsushita. This isn’t a huge deal because Philips is a better lamp than Matsushita anyway, which is probably why JVC switched lamp manufacturers. The price tag was pretty steep though, $195 for an OEM lamp and housing made by Philips? Other places that are authorized Philips dealers sell for around $160-180, but we ordered anyway in the name of science and consumer protection. Upon further inspection, an identical listing on the site has the lamp with the same picture listed for $92. We ordered both through two different proxies to remain anonymous.

We received the products today and both were identical. Both were generic lamps and the only thing OEM about the lamps were their housing. It seems they are re-lamping generic lamps into an original JVC TS-CL110UAA housing.

Inspect the photos below of an actual OEM Matsushita lamp with housing and a new generic with original housing.

TS-CL110UAA OEM vs Generic

As you can see:
A. The OEM lamp has a soldered connection to the ballast wiring. The lamp uses ceramic to seal the lamp–common with the big brands.
B. The OEM case has been sealed and a warranty sticker has been placed on the lamp unit by the warranty company.
C. The lamp is sealed, unlike the generic.
D. The generic seems to fit well in the housing, but it’s face has 4 cuts in it. This means the lamp isn’t sealed.
E. The generic lamp uses a nut on the post of the lamp, which sits on a plastic composite. This is both hazardous and prone to breakage. The generic lamp probably has a life of about 6 months at most.

You can often tell what a generic looks like by what’s on the lamp: nothing. Sometimes there will be a model number, but usually there’s no brand name associated with the lamp–and of course, the price is a lot lower, and the warranty is a lot less than a brand name product. You definitely get what you pay for!

We’re particularly surprised at this online merchant for selling a generic lamp for such a high price. We can only hope it was some sort of shipping error, instead of us paying almost $200 for an inferior product that will only last a handful of months.

How Many People Need Lamps?

Tuesday, November 18th, 2008

Recently, Luth Research, a leader in survey design and research study, conducted a survey of over 160,000 Americans to find out what kind televisions they owned. With Luth Research’s assistance, Lamp Research will aim to find out how many Americans have a need for digital projection lamps. This research study was commissioned by MI Technologies, Inc., owner of lamp retailer — an authorized Philips distributor.

First, the data:

TOTAL Conventional / CRT Plasma Flat Screen LCD Flat screen Projection Other, Please Specify
162855 125908 29345 55302 12176 2495
100.00% 77.31% 18.02% 33.96% 7.48% 1.53%

(Click to enlarge graph)

Next, we’ll analyze the numbers to find out two things: How many lamps need to be produced by OEM Manufacturer Philips Lighting, and how many Americans will need lamps if lamps last approximately 6,000 hours.

We know that over 290 million Americans own televisions (Cal State University Northridge), so if we were to make an educated guess using the date collected by Luth Research, we could say that approximately 21 million Americans own some sort of projection television at home.  From other industry sources, we also know that as of 2004, over 5 million DLPs have been sold. Obviously more have been sold since then, but we can use 2004 numbers to say that there are at least 23.8% of projection televisions owned by Americans today are DLPs. This is only about 2%, but that doesn’t include LCD projection or other consumer electronics that utilize digital light projection.

According to the Luth Research Study, of the 12,000 Americans surveyed with projection televisions, over 70% have a Sony, Panasonic, Samsung, RCA, Mitsubishi, or Hitachi projection television sets. This means that there are many owners of digital projection lighting television sets out there with a name brand set using name brand equipment. That market is big, and while it’s not growing as it used to, the consumer base is there and millions of digital projection lamps will be needed in the near future!

Of the manufactures listed, most use Philips as their OEM lamp, and by our projections, Philips will need to produce over a million lamps per month over the course of the next few years to meet the demands of both DLP and LCD projection manufacturers, and consumer replacement parts.

Philips vs. Osram Lamps

Monday, October 27th, 2008

In an ongoing effort to provide the most sensible and accurate data, we’re still analyzing the results of our Philips vs Osram survey. We’ll get back to you shortly!

July Flash Survey

Saturday, July 19th, 2008

We conducted a consumer survey in July of 122 Samsung and Mitsubishi DLP owners.

We asked: “What kind of issues have you experienced with your Samsung or Mitsubishi DLP television set in the past two years?”

The answers ranged from replacing the lamp to replacing the light engine.

Brand Name vs Generic

Friday, July 18th, 2008

Why is it so important to buy brand name components when purchasing a high performance lamp for your DLP or LCD television? The answer won’t shock you, but you’ll think twice before buying generic.

First of all, let me preface by saying there is nothing wrong with purchasing generic parts. With some electronic components or consumable parts, generic is the most cost-effective way to go. The same goes for DLP and LCD projection lighting. Generic can be a great for your wallet in the short-term, but you may kick yourself 4 months down the line when your generic lamp goes kaput.

Hg, or mercury, vapor lamps are under extremely high pressure and it all comes down to the manufacturing process. The better the process, the better the lamp. There are two main parts to a UHP lamp, the lighting element, sometimes called the burner, and the reflector. Philips used to manufacture both in Belgium, but as demand and costs grew, Philips started manufacturing the reflector in China. The burners are still said to be manufactured in Europe since it’s a trade secret–and for good reason too since the burner is what makes the lamp ignition possible. For example, here’s a Philips E23h:

Philips UHP 100W/120W 1.0 E23

• Customer part#: PHI/378
• Lamp Application: RP-TV
• Reflector type: Elliptical E23
• Arc gap: 1.0 mm
• Power: 100W/120W
• Ignition voltage: Ignition voltage 20kV ± 5kV
• Light output typical * : 4100 lumen (in 120W mode)
• Average Life time ** : > 6000 hrs
• Environmental: RoHS and WEEE compliant
