how long will they last?

I had these last a little over one year (roughly 22,000 miles). My car uses the low-beam 9007 filament to power my day time running lamps so it's literally on all the time. Much better than most of the other Sylvania bulbs I have tried in the past. Totally worth it to have the brighter output on the road. Saved me a few times by being able to see deer on the side of the road before they jumped in front of me.

11 months for me, then one of the low beams burned out.The low beams are daytime running, they are on whenever the car is running.

not sure. i kept them for a few months before use and they still worked fine. it seems to me that they should last for a pretty long time

As long as you keep them dry they will last. I have some over a year old. Greg

They usually can last a year.....but I personally notice a difference after 6 months.

Don't know but I imagine that they will eventually wear out. So far working well - the red lights let you know.

I've only had mine for about 2 months, so I can't speak for how long they last. Fortunately, no issues thus far with them.

My assumption is they should last virtually forever, each package is sealed. I buy, and keep them for years.

It depends on how heavy the usage is on your system. They usually last about 3 to 4 months with our system.

Hard to say how long they will last as that depends on the surface of the floor (the smoother the longer they will last, the rougher, the quicker they will wear, think of sand paper wearing them down). Ours are 6 months old on stools used at a kitchen island on a new smooth hardwood floor, so slid multiple times per day and so far they look almost as good as new, with slight crushing, but that would be expected with felt from day one when it gets compressed the first time. For the price, and how they are holding up so far I would recommend them. Take it for what it is worth, but I am an electrical engineer who works with electrical and non-electrical consumer products.

For the price, it will last a while, but how long i can not tell you because i have only had them for almost 2 months.

I have not owned it long enough to determine this. They have lasted at least a month so far. Sorry...

They should last you about three months. I am just now replacing the black and the color is still at 70%. But I would say they are on the minimal side.

As long as they are not open they last awhile. Even if opened, if closed tight will last.

I believe they are guaranteed for 10 years. I have had mine for 2 years and love it.

they will last quite a while stored but in a device thats not even on they will start to diminish

I don't know how often you use them but I have had some for up to 6 months and haven't any trouble with them. Hope this has been helpful. Thanks Bert

They last ok.. Like 4-5 hours.. I mean they were literally $1 each-) so the quality matches the price-)
