I ordered this bulb as a replacement for my BenQ projector.  It lasted all of two months before it went out.  I do not use my projector on a regular basis, usually when entertaining, parties, etc.  I purchased the bulb in October. Used my projector during Thanksgiving and Christmas.  Went to turn it on New Years' and the bulb had gone out.  I originally thought it was the projector because the bulb was new.  I finally contacted BenQ directly to see if there was something wrong with the projector.  They confirmed that it was the bulb.  "It appears the bulb purchased is a non-OEM replacement".  Be careful when replacing bulbs from other sources.

I took a chance buying a cheap bulb like this and thats exactlly what they sent me, a piece of crap, 2 weeks and already done, words of wisdom ," buy a more expensive bulb" preferably one the actual manufacturer makes. I waited past 30 days to contact Amazon about it and now they told me to contact the business that makes the bulb Power Warehouse and it goes to a voicemailbox that is full, they stuck it to me from every angle, hope this help the next buyer

I bought this bulb in April last year and it worked fine but all of sudden 1 of them went dark. I decided to go with Philips after reading all the reviews and was made to believe that it will last forever (I mean longer than 10 months at least) but now I'm not sure what should I look for when buying the replacement. I'm sure it's not the voltage fluctuation or any other factor since the other bought along with it is still working fine. I'm going to call the Philips customer service and complain. Let's see if they can tell me what went wrong.

Bulb is worst than the one I replaced.  It gives the picture "a green tint" and no matter how I try to adjust the picture it remains green and dark.  I would like a refund of my money.

The bulb that was sent to me wasn't a good bulb.  I purchased two of them and neither one worked in my Sony television.

I really wanted this bulb to work for multiple reasons.  When I bought it six months ago (June 2013), I tried it out in a few places, and eventually used it in a two-bulb kitchen light fixture.  The second bulb was an incandescent bulb.

One of the two burned out more than a month ago, but I didn't bother to replace it so I don't know which one.  The other burned out a few days ago.  Best case scenario was that this LED bulb only lasted six months.

Upon doing a little research, I found that "heat" is the enemy of this type of light bulb.  Perhaps if I had used two LED bulbs in the fixture, the bulb would have lasted longer.  I didn't find a warning about this in the seller's description.

The bulb has a three year warranty, but I couldn't find anywhere on the Amazon site anything more about that, just the claim that there was a warranty.  I guess that I could try to return the bulb to Amazon (after 6 months?), but I really don't care to pack it up and pay the postage for a $10 item - I'd rather just complain.  It's clear that the seller doesn't want to "encourage" buyers to execute the warranty.

I think that LED bulbs are the future, and I'll try them again but from a different seller.

The adapter to the bulb was slightly smaller than what it needed to be and would not plug in to slot correctly!

The light is on the blue side which I would expect from an LED. It is what I wanted and the light is about the same as a 50 Watt Incandescent bulb. In less than a month, one of the three bulbs stopped working.

For a few days, I could tighten it or loosen it a little and it would work for a short time, then is stopped working completely. I tried the other bulbs in this socket to determine if it was a socket problem, it wasn't. I tried the faulty bulb in two other sockets and it did not work in either.

Now, I know that it says there is a 2 year warranty, and that there is a 90 day money back guarantee. The return shipping on one bulb is prohibitive (compared to the price) and no where on the package does it mention how to return these bulbs only in the Amazon item page does it mention this.

If I were interested enough in these bulbs to be reading this review, I would search the other reviews to see if there are a significant number of similar issues before spending my money.

One of the light fixtures doesn't work. Can I get a replacement or will I have to return the entire thing?
