Question: Is there really a difference in an OEM and a generic model for the Sony XL-5200 lamp?
Document: Thought this might be a decent, inexpensive, alternative. Wasn't as bright as Philips bulb it replaced, not a massive difference, but noticeable. Then 3-4 weeks later went really dim. Pay the extra money and get a genuine Philips bulb. Get a bare bulb (minus the housing). The real deal bulb has screw posts for use in the original Sony housing. This generic has soldered on points..ie..not replaceable.
We have a Sony Projection TV and the Sony XL - 5200 replacement lamp worked perfectly. Bought a spare so we have one on hand just in case the lamp goes out again.Greta Haggerty
This lamp was a gift to a friend. She really likes it and look forward to a lone life of the product.
Don't waste your money on this generic lamp. Spend the $100 for a quality lamp! Learned my lesson the hard way! !
Lamp came sooner than I anticipated and fit just perfectly. I had purchased a Sony 50&#34; SXRD Projection Television, Model No. KDS-50A2000 from a Thrift Store for $30. I ordered the lamp and installed it upon arrival and the unit works as good as new. Ended up spending about $65 total for a great 50&#34; High Definition television. It's been working for the past 3 weeks and so far, so good. We'll see how long the bulb lasts.
This backlight provides illumination for a Sony rear projection HD, 60 inch TV. Recently, the picture seemed to be dimming especially in high ambient light conditions. It would also take several minutes for the picture to come up to full brilliance such as it was. The bulb finally went out and I was confronted with a $250 OEM replacement. Conversly, this replacement was considerably less than $50.00 and was received on-time with no problems.
I received my bulb that I purhased in the time they quoted. It's an ok bulb, definately not Sony quality but worth the $30.00 to get my tv up and running again. My picture is at a medium brightness and colors are not very vivid. I tried adjusting the brightness of my tv from the original setting with little difference. You get what you pay for....next time I will buy a genuine Sony replacement.
The build quality is as good as the OEM's I've been buying and it's less than half the cost. One-year warranty is a big bonus on this particular lamp, many of the less expensive ones only have 90 days. Picture is nice and bright, no flickering and is exactly the same as a new OEM lamp. If it lasts as long as the other lamps I've bought in the past, I'll come right back here again. :)
This worked out really well for our tv we bought in 2006. We even went back to buy a second one for future use.
This lamp is produces a DARK picture! I will put up with this because I refuse to pay $300. 00 for 1 lamp from Sony!
Answer: Absolutely big difference,go with the oem...trust me
