How many hours does the lamp last typically?

Not sure about actual hours but I have used mine, for business presentations, probably for 25 total hours thus far and no problems.

I can't say, because they always BROKE first! Seriously. I had TWO of these in my classroom in the past year, and both broke before the lamp burned out. Granted, they were used a good deal, but this was ridiculous!

I cant tell, we had this for months but we only used it occasionally. So far its been working great.

There is no way to tell how many hours are left on the lamp except when it stops working. There is no minute "counter" in the menu setting with these DLP T.V.'s either. That being said, I replaced mine before the lamp burned out and I did notice a dramatic improvement with the picture quality, especially with the brightness of the display. If you want a general rule of thumb with regard to when to replace the bulb, consider and ask yourself if you notice the picture being dimmer that you remember it being when it was newer. If you bulb is more than 3 years old consider replacing with a new on and using the old one as a emergency back up.

I don't recall after how long I had to change the bulb, but one, I do not keep it on all day at need. I have the lamp at my desk at work, so it is on for 8 1/2 hours a day, 5 days a week. The bulb lasts for quite some time, at least a year I believe before you have to change the bulb.

I did some math with my probable maximum time of use and i figured at a MINIMUM the lamp would last me 10-15 yrs in bulb life. I'm almost sure by that time something more advanced or that i like better will come along and this lamp will be going to goodwill or the landfill.

This lamp is supposed to last up to 10,000 hours, so you would replace the lamp not the bulb.

I don't use mine very often (a few minutes several times a week). I've had the lamp for at least 10 years and don't recall ever replacing the bulb.

The life of the lamp is 30000 hours based on specification given on Asus website. I don't think lamp is replaceable, moreover you will never need replacement, till the time you need replacement, you will be technologically compelled to buy a new projector.

I recall only 90days. My last lamp from this manufacturer lasted over two years.

By the way, the bulb in it is rated for 100,000 hours. Probably about 10,000 years for me!! ;-)

Not long. Seems like mine was dead after 4-5 hours of use over several months. Never replaced the battery so I've been stuck with a white, plastic bulb for years now. Wouldn't purchase again.

I've had mine two years. Ovevthe past 6 months, I've taken to leaving it on all day (on the weekends when I'm home). I use it like a regular lamp. No problems.May not want to use it as a reading lamp during the evening in the case it keeps one awake.

Yes, however they are much more expensive. A new lamp from Phillips can last up to 6000hrs or 2-3yrs depending how often you use the TV @50% brightness.

depends on how much sunlight you get, but I'd be willing bet it would last a few hours at least. Mine only comes on for a few mins at night when I come home from work. That's all I need it for. Works great, no problems with it yet. Very bright.

I routinely leave over 12hrs a day. 3 things though, I have air circulation the lamps are pointing upwards, and as per manufacturer I use CFLs

The LEDs are built into the lamp. The LEDs last for up to 35,000 hours which is 25-30 years!

I've left these dimmers switched on for more than a year (never flipped the switch on the dimmer pack). Although, they haven't been in active use all that time. I think the longest time a lamp has been on through the dimmer is about 14 hours in my experience. The only real problem I've had with them is that the fuses usually need to be changed when lamps blow.

I haven't had any issues with my lamp and I've had mine for over a year. The only negative thing I've found is that I do have to replace the batteries every 1-2 months, but it's not that much of an inconvenience.
