Reviews are true.  11 months and 20 days LED display fails

I ignored bad reviews because I wanted the convenience of one remote.  Big mistake.  Failed today like all of the others who have given this a 1 star rating.  BEWARE!!

Started buying LED bulbs last summer.  Did quite a bit of research and found LOHAS LED from Amazon.  Ordered a 3-pack in August 2015 to try them out.  Was pleased to what appeared to be a high quality LED bulb, but after six months of use, a all three bulbs began to strobe.  After somewhat of a lengthy email exchange, the company made good on their warranty shipping me three new units out of a Chicago warehouse.
Slightly concerned about my investment with this company at this point and hoping that the strobing problem has since been addressed in their manufacturing process and will not surface with my more recent purchases.

UPDATE:: October 2016  2 more of 6 bulbs purchased in 10/2015 have failed just inside the warranty period.  Warranty replacements have been requested.

after less than 2 years of occasional use (about every other weekend), the display went bad, unreadable, rendering this unit completely unusable as I can't change settings. This has been in a sound box, used indoors, rolled from one end of a room to another, hardly any kind of a harsh environment. Lexicon quoted me "around" $160 to repair. Not worth it. While I was happy with this effects processor when I could use it, considering its reliability I would suggest you avoid this brand.

Edit 6/28/17: After going months with the display looking like it does in the attached image, the display is suddenly fine now. I didn't do anything that I normally don't do. Just turned it on one time and the display was readable.

It's been about a month now and so far so good. We'll see as the previous 4 kits I've purchased (NOT from this seller) all failed from between 6 months to 18 months... WELL shy of the '30,000-hour life span' of LEDs. These are set up as my high-beams though so they will see less use than low-beams. I WILL update as time goes on.

Even with the extraordinary claims of 30,000 hour life, these bulbs fail in 6 months.  I believe it is not the LEDs themselves failing, but rather the power supply that drops the voltage from 120 VAC down to the DC voltage required to run the LED.

I bought the LED light and AC adapter in October of 2005.  In June of 2006 I returned it because one of the two LEDs went out.  Amazon warranty is only good for 30 days.  Sent it to Zelco and they replaced it.  A few months later the same thing happened and I again sent it to Zelco for replacement-they did.  Then again!  Just the other evening the "10 year" LED failed once more.  Four times in two years!  I give up.  The reason I bought it in the first place was so I don't have to constantly change bulbs in the incandescent version.  If you purchase this light be sure to save your receipt and set aside some postage!

Fine for as long as they last: I've had several, all lasted maximum one year.  After that the display fades out completely.

UPDATE: January 2016, the backlight died (two of the diodes died and made the whole strip not lighting up) after slightly more than two years. Warranty is only 1year. Such a lifetime is pathetic! I bought a 40" VIZIO next, again using it mainly as a TV monitor.

I wanted to use this LG TV mainly as a computer monitor. You have to name the input to PC - it will make the PC picture look way better. It worked nicely 2-3 days - nice colors, contrast, crisp text, and many settings available to tweak the picture saturation, hue, contrast etc. The sound is not as clear as Vizio but is ok.

I was able to set the color temperature to C20 which makes the white cool (blue hue) on a webpage or a document. This is how white is supposed to look in my opinion, not some grey or yellowish white I've seen on other monitors.

After a few days the TV started to shut itself off. It seems that after some time working it 'overheats' or something shortcuts and it shuts off. Then it turns on again randomly. Then off again. Setting the clock, as someone here suggested, did not solve the issue. It's simply faulty - the same problem repeats as a PC monitor, as a TV, and when hooked to my laptop.

Looks like there is a bunch of faulty TV's out there that are being resold without proper checkup. Mine is "used, as new" and is going back. If you buy one of those, make sure it is not used or you are running a high risk of getting a faulty one.

Update September 30th: I got the same model, NEW in the box, from a local seller. It works without any problems and I chose it over Samsung UN32EH5300, because the LG has more settings available to tweak when used as a PC monitor and the picture looks way fresher and overall better on LG.

Lasted 1 year & 2 weeks. then the main LED burnt out. VERY expensive for a 1-year product. I checked on the "Nitecore" website. No option to repair.

I'm giving this a two star review for now, but I may change that later: It works perfectly until the LEDs fail. For me, this was 3 months into owning it, and it's extremely inconvenient to not visually know which efx loops are active. I'm currently having it replaced, as I purchased an Asurion protection plan at the same time. If my first one was a lemon, my review will increase to five stars.

Mine lasted a little over 4 months and then the rocker switch started failing in one of it's positions.  20,000 hour LEDs are not much use if the rocker switch dies.  At this point I am stuck  in high intensity mode only.  At least until that side of the rocker switch fails too.

I purchased these Sep 2015. AS of June 2016, one unit has already failed completely ....no where near the 50,000 hour estimated life span. Expensive LED lights SHOULD last more than nine months of light residential use. I'm not sure if I'll replace the dead unit with the same brand.

The first one failed after about 3 months.  The problem was NOT the power brick; I replaced it to no avail.  The seller was nice enough to send a replacement, but then the replacement failed after about 2 months.  The panel itself produces gorgeous images, but there seem to be controller and/or comm chip problems that cause the monitor to become unusable quickly.  After about 2 months the first one I received started to flicker down to a dim state.  I could adjust the brightness back up but within a few minutes it would flicker down to dimness again.  The replacement monitor stopped being recognized by my computer after the computer booted up; it would remain dark and not be detected by the Display Control Panel.  Oddly, the failures of both units were presaged by the power light malfunctioning for about a month.

Save your Money...these lights fail within 90 days...after the return policy expires!
I purchased these 10 LED 180 Lumen Solar Motion lights based on the reviews and the high lumen output. I mounted them next to my yard gate & along my walkway. the 180 lumen offers good visibility to any path or gate/entry. Within a week I received an email from the seller saying I should contact them if I had any problems since they had changed their manufacturer & also received reports of faulty product. I didn't think much of it at the time since I had only had them for a week and they were working fine. I received a second email within a week or 2 of the first & again didn't pay much attention....I wish I had! Just after the 1 month return period lapsed, the first light stopped working entirely. within a couple weeks of that the second light would turn on randomly & then started to turn on but only produce about 10 lumen of light. 90 days later, I have one working light & it is starting to show the same signs of failure as the first 2. While I commend the company for letting me know they had changed their manufacturer I think they should have also extended their warranty period since they apparently knew of the defective products.

Mine died with "Err" on the display after about 14 months.  The instruction manual (if you can call it that) says that this code means, "Unit malfunction, replace".  Hardly worth it, honestly.

Purchased 6 lights. The first failed within a month and the second failed 6 months from purchase. The lights are on for the recommended time -- 3/4 hours per day. The color of the light itself is really pleasing as it's not too yellow. Unfortunately, the rather short life of these LED bulbs makes them not a long term solution. I'll be looking for another brand at this point.

(Update 1/28) -- and now we're at 7 months from purchase and three more have gone out. I've since purchased Philips Soft White LEDs which are maybe another $1-2 more per unit, but I have had zero issues with them so far.

I bought one of these three years ago (2012) and we have used it for our primary TV/video viewing since then.  However, about a week ago, the Blue LED appears to have failed.  In three years, I would estimate we've used it for 2500-3000 hours, so this is less than 10% of the advertised lifetime.  Since it was after the end of the two-year warranty, LG would not do anything about it.  I pointed out to them that even if a person turned on the unit when they got home and ran it continuously for the two-year warranty period, it would only be about 17,000 hours, so they would have no way of getting close to the 30,000 hour lifetime claimed by LG within the warranty period.

So, buyers beware!  The LED lifetime is not 30,000 hours, but more like 3,000 hours!  That is about what I used to get from my other projector that used a conventional bulb!  I haven't seen anything that shows where they came up with the 30,000 hour number, and they certainly don't support their products like they expect them to last that long!

The photo below shows my computer screen on top, and the projected image below.  Beware, this could be what you are looking at after a couple of years!
