New Year, New JVC Research

Tuesday, February 3rd, 2009

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

Naughty Internet Retailers & Misleading Keywords

Wednesday, December 24th, 2008

We’ve all heard the differences between OEM Replacement and OEM Compatible and OEM Original, but here at lamp research, we’ve seen it diluted in the keywords of a lot of online retailers of Philips and Osram lamp products.

Buyer Beware! Don’t buy OEM Compatible or Replacement lamps. The word compatible usually means a generic, while replacement can mean a variety of things. If you have any doubt in your mind, call the company before you buy. Ask if it’s the same lamp that came in your TV or not! Our general rule of thumb here is that the best lamps are usually Philips which is 100% compatible with most television lamps. If not a Philips, try an Osram. Then if not Osram, think again before you buy. Lamps are usually designed to work with the ballast that power them. Philips lamps are always preferred with a Philips lamp driver (or ballast) in most circumstances!

Here are some examples of websites listing OEM Compatible, Replacement, or Original. We will be examining the Philips LCOS television with lamp unit part number 312243871310. The original lamp is manufactured by Philips Lighting.

The company claims to not sell OEM replacements!

[caption id="attachment_83" align="aligncenter" width="300" caption="But they do offer an OEM replacement! The listing doesn't show if it's a Philips lamp or not, but this company is rumored to be the same company as River Valley Electronics, so we know they don't sell Philips."]Clearly someone didn't get the memo.[/caption]

Discount-Merchant.com sells an Original OEM Philips, but says it's an original Philips/Magnavox! We know DM is one of the largest Philips distributors, so we'll let that slide this time.

[caption id="attachment_91" align="aligncenter" width="300" caption="PartStore has the best listing, but their prices are quite high. You can definitely find it cheaper elsewhere. PartStore is a good source for other parts you can't find anywhere else."]PartStore has the best listing, but their prices are quite high.[/caption]
This company is known to sell Osram, not Philips. In this case, OEM Replacement is very misleading!

This company is known to sell Osram, not Philips. In this case, OEM Replacement is very misleading! buyer Beware! Don't be fooled into buying an Osram lamp for a Philips TV, when Philips is obviously the better brand.

We're not sure if they are OEM or not, but they claim that it is (And that's one really good price if it is!) If you get an Osram from DiscountTVLamps.com for this lamp model or Philips part number, ask for an exchange!

LampResearch.com has actually ordered parts from most of these internet retailers before and we can tell you that you get what you pay for, so call and ask before you order. Ask for genuine. Ask for OEM. Ask if they are an official, authorized distributor.

We’ll keep updating this list, but it’s safe to say, stay away from companies that mislead you on OEM product. You could buy a cheaper product, but you’ll pay for it in the end! As we stated before, if you aren’t sure about it, call the company and ask. Better yet, call a few companies. Making 2-3 phone calls to reputable dealers will save you $$$ in the long run.

So River Valley Electronics makes our naughty list for misleading customers, while other internet retailers for OEM lamps receive kudos. This Christmas season, make sure you buy an original lamp for your television, and Santa won’t leave you a lump of coal!

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

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.

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

We’re still researching some of the generic manufacturers, so we’ll continue to update this news item as time allows.

What is Generic?

Monday, May 12th, 2008

Generic lamps are compatible or copy lamps not manufactured by the OEM lamp manufacturing company. A generic lamp will usually cost significantly less than an OEM product because of:

  • inferior workmanship quality
  • lower manufacturing costs
  • poor and inconsistent product lifespan

If you’re buying a generic high performance lamp, be prepared to eat the cost of its usage. An OEM product may last 3 times as long for only a few extra dollars. There is risk of premature explosion and loss of lumens associated with purchasing an off-brand, or generic lamp product.

For example: If you buy an OEM Philips for your television, it may cost about $150, but last you 3 years. If you purchase an off-brand, generic product for $100, you will have save $50, but the lamp may only last about 6 months to 1 year. The cost-benefit analysis maintains you’d be better off purchasing the OEM lamp. You can even purchase a compatible brand name such as Osram–though it may not last as long as the Philips, it has a more consistant lilfespan than the generic manufacturer.

If you’re concerned about purchasing generic products, or have purchased a generic product by mistake, call the merchant you purchased the product from. It is your right to ask them if they sell an original product for your television–anything else is misleading. You should also find out which brands are OEM for your television.

Explanation of Key Terms

UHP Replacement Lamps
Explanation of key terms

Lamp modules – are made up of two main elements: the lamp (or bulb) and the cage (or housing) including electrical connector.

Lamps – are ultra high-performance light bulbs developed by the world leaders in lighting technology working in close cooperation with the projector & rear projection television manufacturers. The lamp (or bulb) is made up of two components: The burner (or lighting element) and the reflector. These are usually manufactured separately often times in different countries) and assembled together to create a UHP lamp.

Lamp module – are housings produced by the projector manufacturers to accurately seat the lamp and enable user replacement (each physically different projector model usually requires its own cage design). Also known as: lamp unit, lamp module, enclosure, cartridge, or housing.

Original Lamps -  are those manufactured by the original lamp developer holding the technology patent (e.g. UHP™ from Philips). Also known as: OEM.

Compatible Lamps – are lamps that are not the same type as the original lamp placed in the projector by the projector manufacturer. Specifications about brightness and lamp life are always based on the lamp system, which is the lamp and electronics that are designed to warrant safe operation and good performance of the system. Non-original lamps could be copy lamps. Also known as: OEM compatible, original Compatible, or aftermarket lamp.

Copy lamps – are lamps produced by unregulated manufacturing companies not holding the technology patents & not pre-installed by any projector manufacturer. Also known as: OEM compatible, original Compatible, generic, aftermarket, or knock-off.

Refurbishing (or re-lamping) – is the process of removing a used lamp from its cage. Also known as: relamping, refurbishing or redeveloping. Refurbished cages and housings usually have nothing to do with the operation of the lamp itself. The cages merely seat the lamp properly, and we recommend purchasing with a used, refurbished, or re-lamped product which is more environmentally and economically  sound. When purchasing new, look for a recycled label. Cages may be recycled and re-developed into a new lamp cage.
