Only 25,000 hours. That means it will only last 2.8 years, not 22 years?

It's based on 3/hrs of day of use, which is 1,095 hours/year, or about 22.83 years. As with any product, using it more or less frequently will extend/reduce the life.In my own case, I've used three of these for more than 3 hours a day for 2.5 years or so, and have not had any issues so far.Also, the lifetime quoted assumes you follow the directions (i.e., don't install this in a *fully* enclosed fixture as the heat buildup will rapidly degrade the LED).

The life in years is given based on an average number of hours per day- not 24/7 operation.

The design of the product is on the basis that it will cease operating after 19,000 hours. The reason for this (as explained in the information accompanying the product) is that the manufacturer wishes to ensure that the user gains a false impression that the unit is working effectively, after it has become exhausted.

If you used this for 8 hours a day, it would last you 10.x years - figure out how many hours a day average you would use it for viewing, divide 30000 by that number and then divide that number by 365 days in a year and thats basically, as long as there are no technical issues with it, how long it should last you, roughly :)

At the very, very least, one year, if not more. I would actually guess 2-3 years.

I think it is 2 yrs. It should last even longer if kept cool, dry and out of light.

Put it in the sun for an hour or two. It is supposed to last two years this way.

I've had mine for just over 2 years and it still works great. As long as you grease the gears every 7 years it should last a long time

i've seen specs with at least 30000 hours. I'm sure this can vary higher as Bryan mentioned.

When mine was new(september 2014), it would go for around 30 hours of use. Now, I get about 2 or 3 hours out of it. I am very disappointed in it. I don't know if I just got a dud, or if they are just lower quality and wear out fast.

From what I've seen, it should be good for about 25-30,000 miles. No sure yet as Iv'e only used it for about 3500 ,miles so far.

Maybe after several months. New, it should last 15 to 30 depending on how you drive

Can't find it from the manual. Suppose the life span of the battery depends very much on usage of special features like the lamp and altimeter. Otherwise, I would expect two years the minimum acceptable life span.

If I recall: it is around 18 months. Don't quote that. It is a product that I have had for 20 years (previous company name). No problems. When this goes out in years to come, I will buy another, maybe a 2500 or 3000

You get about 5000 hours then you are just done with that unit. That is my understanding.

It is a fairly cheaply made product, so I think it is unlikely it will last a long time. Probably 5-7 years at best.

I have no bias for this, but that's kind of a silly question. You want something to last for years, at this cheap price? Good luck with that! As for this product, it works well if you want to cool it quickly and use it quickly. It does not last beyond 30 mins or so.

No. Should last for a long period of time. Many years if maintained properly.
