would anyone recommend buying a used LED: Is that a good idea??

Brand name......don't bother though....I returned mine....buy a LED LENDSER...you'll love it http://www.amazon.com/gp/product/B0054KX6YS/ref=ox_sc_sfl_title_7?ie=UTF8&psc=1&smid=A1JGIS49I66QK2

Oh...and id recommend also. Make sure to buy the 5k light color HIDs. They will be the closest to the LEDs. (Which are also awesome as parking lamps :)

If that light was left on for 5 hours per day , every day , it would last 27 years. I think it would be ok to buy a new one then. Now if you only used it 5 days per week it would last even longer of course. That is the benefit if LEDs - they should outlast the fixtures practical use. With that said, Looking at the light I'm not sure how you would change the light strip.

It would probably be easier and more cost effective to change the fixture if you want LED's. I'm not sure that the savings warrant that.

This Illuminator has around 200 LED's. If you have never replaced an LED you need equipment, like tiny soldering tip, tiny tools, and the ability to work in small areas. I have one of these illuminators. If all LED's were blown by something like lightning or power problems, I would not attempt a rebuild. If just half a dozen have blown, you will not notice the difference in lighting, so would not work on them. I frequently change out the colored LED in computer fans ( most lit ones use 4 LEDs ). I buy the colored ones from Amazon, but do not remember the cost, which means I did not scream about the high price, which I often do. They are fairly cheap, as I remember. Never have worked with Infrared LED, just visible light models. This illuminator requires 850 nanometer, which I have no idea of cost. Just check Amazon. They have a 10-pack of 850 nm units for $ 2.56. Be sure to read the customer comment. My engineering experience with LED's occurred when the LED just came to market. Not much has changed except a very large price drop in the last 50 years. Not all LEDs are the same circular size. I have to watch that when changing colors on computer equipment, like the colored fans. Oh, when working with soldered-in like these, you do need a motor operated vaccuum pump to quickly 'suck' the solder out just as it goes liquid. Those hand operated units, like the "solder sucker" are too cumbersome to get into that circuit board. I built my solder sucker about 30 years ago, for I do a lot of unsoldering on really small parts. Must admit I have never taken my illuminator apart to see how it is put together. If I had around 25 or so of the LED's shot, would probably order a new one, take the faulty unit apart to study the construction, then save all the LED's for the next time. The LEDs I have used from Amazon have been quite hearty, ie never broke one, nor melted one. I should tell you to forget fixing the unit, HOWEVER if it were mine, I gotta fix it. Good Luck

For all intents and purposes LCD is old technology. You are certainly better off getting the LED

That would be a question for the manufacturer. That's a lot of playing! This is what their website says:All our LED lamps come with the LEDs pre-installed in the lamp shade. The LEDs will work for up to 50,000 hours with our unmatched manufacturer's 2-year warranty. This means that if you use your lamp 5 hours a day, then the LEDs should last 10,000 days or more. We will replace the LED component for you during the warranty period if it does go out. However, if the LEDs need to be replaced after the warranty period, we do sell replacement LED components for $15-$25 each, depending upon your model. That would be a question for the manufacturer.

Don't worry, by the time you get the operating instructions the LED will quit working. I gave up on them after the second one.

wow- I've had different LEDs for as long as 4+ years now. None dead. I'd definitely contact whoever you bought it from. they should replace it if they;re decent...

Actually, I don't think you can replace the bulbs. LEDs are usually good for about 25,000 hours. That's about 20 years.What did you have in mind.I don't know about you but I'll be ready for a new technology magnifying glass way before that.Batteries will be your issue depending on how much you use it not the LEDs.You need a really small Phillips screwdriver to replace them and it takes three. The cover is real bitch to get off. You need a really small Flathead screwdriver to pry it off. Thank God the screw is held in place in the cover or you would probably loos it.A small screwdriver set & a couple of rounds of changing batteries and it's no big deal.

if I understand the question correctly, you want to replace the LED screen on the set. I don't think that would be worth the investment. You could more than likely replace the entire set for less. A power surge could have possibly done more damage to the other electronics.

LEDs last a long time and the possibility of a defect should show up before the warranty expires. It'll probably last 30 years and at that time there will most likely be an even better LED or other technology to replace it with.

I am using the very expensive LED's. These are very efficient and are supposed to last a looong time. For the initial price they need to.

I can only can give my opinion but, in any past experience I have had regarding LED displays like this is not good.Generally, you would have to replaceThe whole display module.... But I might be wrong. :0/

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 been using it pretty heavily for 6 months and the LEDs work perfectly. The only thing that has degraded are the wasd keys from being used too often, and that's just a little paint coming off the top.
