How long will the bulb last if it comes on for 2 hours a night?

It's a motion detector light, so I don't see why it should stay on for 2 hours. Mine is set for 10 minutes, or so. I've had mine for a year or two, and haven't yet replaced the bulb.

the light can be set to stay on for up to 15 minutes when activated by motion. I have had mine over a year and have not had to change the bulb yet. I expect it to last several years.

I had my light on 24/7 and the bulb lasted a year. I kept it on by "tricking" it with a remote control plug in (turning it off and on quickly). I could never remember to turn it off and on at a regular basis, so I just kept it on all the time. For some reason the remote overrode the motion detection, either that or the motion detection simply didn't work.

Not exactly sure how long mine comes on each night but it does come on, off & on throughout the night, and I have had my first one over a year and have not changed the bulb yet.

It lasted all last winter. A good rule rule might be to use the advertised bulb life and reduce by say 20% for the triggered on and offs.

I use these every night, on 500 lumen, for about 7 minutes. They last about 2 weeks on average. Same with other brands. The other settings will work a while longer but I need the bright light.

Mine have lasted over 2 years thus far, 24/7 usage and I have two units. I highly reCommend this, you aren't going to find a bulb that will last half as long, either way. It's a piece of mind.

It uses an LED lamp, so it should last upwards of 50,000 hours. You probably won't ever have to replace it; at 4 hours of use every day it will last you over 30 years.

Usually new bulbs have a total of 900 hrs but by the time they reach 800 they have lost a lot of life ... I change mine every 800 so it depends on your preference !

Depending on the setting, if its on high it will stay on for an hour, med two hours, and low for three hours. Hope that helps.

The package says 2000 hours. For the most part we have found that to be true. We have 18 of these in our new home. Occassionally you will get a dud. Just call Phillips for a replacement bulb.

The BlueMD bulb is rated to last 10,000 hours, which equates to about 30,000 treatments at 20 minutes each. We generally put the life expectancy of the bulb at around 5 years, but it will obviously last much longer if you go by the hour rating on the bulb. Also, should you ever need a replacement bulb, we sell them to existing customer by contacting us directly. Thanks!

Although my bulb is still going strong at 2000 hours. U should check on that because it's supposed to last twice that and so far I've had no issues

You turn the light on when you plug it in 8 hours before you want it to begin lighting. It will flash on and off twice so you know it is working. After 8 hours it will begin to light. It takes about 30 minutes to fully light. I'm not sure how long it stays light once it is at full power- about one hour. We only switch the lamp off Friday night so it won't go on for the weekend and switch it back on Sunday. We love this adapter!

Probably an hour or two... But it really depends how long the string of LED are... I can't really say for sure... They're not that costly so buy 'em and try 'em to see... If you have a dimmer they will last longer.

I would say AT LEAST 8 hours, but probably substantially longer. I accidentally left them on the whole night and in the morning they were still going (this was also after weeks of use-where they were on several hours a night). I'm only saying 8 to be on the safe side, and to ensure that they remain bright enough, etc.

Not long, about 3 to 4 min. I have it in the garage. The problem is when I work in the garage, it turns off after a few min and I have to move around to turn it back up again. May need an alternative light source.

Since this light uses an LED bulb you can expect 5 hours out of the 4 AA batteries it takes to power it. The bulb itself will give you 100,000 hours or about 10 years of use out of it just keep enough batteries on hand and you'll be fine

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.

They purport to last 2000 hours. This current bulb has lasted a little over 1200 hours so far and it's in really good condition. Are you getting the "Replace Lamp" warning?

Hi there. I got mine lamp last March and the bulb that came with it just burned out about 2 weeks ago. So a solid year for me and I've used it at least 8 hours a day, Monday-Friday in my home office, where I work full-time. Easy to change the bulb, too. The cover snaps right off and you just pop it out and plug in a replacement.
