All the USB LED lights I've bought lost half their brightness after about 40 hours. Has anybody used theirs for extended periods?

Have only had for a few months, using as a night light about 4 hours a day. So far no difference that I can see.Have used the Satechi desk lamp ( 99.00 ) for over 80 hours it still is just as bright as when new,

This is more like an accent light at maybe 20 watts equivalent. It is just enough to read if you have good vision, but is great at illuminating an area. I have it on the entire time my computer is on and has clocked at least 16 hours a day for several weeks without any dimming.

I've had mine running 8-9 hours a day for the last two weeks, plus lots of time since my review. No brightness issues that I've noticed. The cause of the diminished brightness in LED products, especially cheap ones, is that the designers intentionally over drive the LEDs to increase the brightness. This also shortens the life of the LED.

They will last through the night but only one (or maybe two) nights. The battery would quickly be extinguished and you would probably spend a lot on replacing the battery every other night. I also use a nightlight but I use a small light that plugs into the wall with a nightlight bulb in it. I also have one of these GE Metal Shade With Flower Design Incandescent Night Light 51386 which works really well. Hope that helps! These Mushroom lights are still fun and are really good for a few hours a night!

How long did the last? What model did you install them on? My answer is if you installed them and they malfunctioned upon installation then you got a defective pair. In the meantime, I'll tell you that mine work really well they get the job done pretty well... However, I have gone through 3 pairs of these because I'm constantly turning my lights on and off (it's my daily driver). However, these LEDs do give my car a modern look :) Hoping to hear back from you soon so I can properly reply.

the whole flashlight is $6 shipped, you just buy a new one... not sure what a "driver" is... you are aware LEDs last over 100,000 hours which is longer than you and I will be alive during sundown.

Hey tuna, I placed a new set of batteries in, placed it on bright setting and left it on...I had to leave 2.5 hours later and I did not detect any significant degrading in light quality. I've used it at 2 hour gigs with the same results. Hope this helps.

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.

An LED will typically burn 50,000 hours or longer before beginning to lose brightness. They don't "burn out" like a traditional bulb.

Hi, Wanted to let you know like all new LED lights its hit and miss I think we've only had one bad but it happened almost immediately I cant give you an hour length because with all LED lights it just depends on how well the bulb was done.That being said they last a long time for the price.

I've left them on for several hours before and haven't had any major issues. It was for photography rather than video. The overhead light did short but I think it had to do with the power source, not the light itself.

On average, LED bulbs last 50,000 hrs which translates to a little less than 6 years of continuous use. Odds are, you're not going to use the light 24/7 so it'll last considerably longer than that. I've been told 25 years, but time will tell. They're very bright. Bought a dimmer switch compatible with LEDs and that solved that.

I have some that get direct light and some that don't. The lights that don't stop working before the lights that do get direct light. That said they do last for 4 or 5 hours. I'm very happy with the lights. Easy to install and they provide a good amount of light. This is my second year with them and they perform like new.

I ran mine for 2.5 hrs on the brightest mode, just to see what it can do. Didn't see any drop in intensity and still had battery left. How much don't know. My other lights are over $200.00 each so was real impressed with how long it lasted so far.

The LED's will probably out live me! They get only slightly warm after running them for a while. They can run all night long no problem. Power efficient too!

Honestly I do not know....these are LED which are rated for gazillion hours so I am not concerned with them burning out ;-)

I did a thorough search and didn't find anything. They're supposed to last for a long time but I buy an extra light to use as a spare and they're pretty inexpensive. Sorry I couldn't be of more help.

Same as John below. I use them on a 160 LED set-up and love 'em!!!! They hold a charge forever with no Flicker or gradual decline. When they are Maxed out, they just go out instead of changing Color temp or brightness. They are awesome!

I found the same thing to be true. They were great at first, so bright I couldn't let my two year old grandson play with them, too bright for his eyes but in less yhan a week they were useless, barely lit up.
