lamp life of some was far below what is listed - but vendor replaced

update 12/21/16:
CRL responded  quickly to the published review below. The earlier email had apparently not been received.  They replaced defective lamps quickly.  Good customer service.  Will update when the replacement lamps have been in use for a while.

previous: I loved the light quality of these lamps until they started flickering  and then burning out after about one year of normal use.  Some are still working, but I would not buy the replacements I need from  this supplier. I wrote to them about the issue & received no response. I am looking for a similar product that is more reliable.

I installed these lights in September of this year. When installing, the first thing you notice is the wire that the specs state is 30" long is WAY short. I was lucky if they were over  8" long. The second thing I noticed was the outer case of the light was dented, dinged and rusted. Could not tell if this was shipping incurred or if they were used previously. Lastly, the mounting bracket is very thin and flimsy. By the time I had it installed, I needed to straighten out the bracket. Once installed, they seemed to work fine. It is now November 16th and they failed several days ago. It has not been three full months and they are flashing like a strobe light. The specs page states they have a year warranty. I have not been able to get a response from the seller to have them replaced. If the lifespan is only 1000 hours, the labor to replace them will negate any savings buying them cheap.
Save yourself the trouble and pay more for a better quality light.

This product was purchased to replace a lamp and housing purchased a few days prior, which failed within minutes of installation. Unfortunately, this product was shipped to me by the VERY SAME vendor, even though I thought I was buying from a different vendor. The vendor is "Exclusive Bulbs."

I paid nearly twice as much for this product as I did for an identical item from the same vendor, which is most definitely a scam. Shame on Amazon for allowing this to happen on their site.

This is absolutely not an OEM lamp assembly. However, a year ago (early 2014) I did order and receive an OEM lamp assembly from this vendor.

My advice is to skip this product. On first installation, the lamp had a noticeable ozone burning rubber smell when the projector was turned on, and the picture began to flicker in black and white. I turned off the BenQ 1070W allowed the cooling cycle to finish and then turned it on again. The picture remained normal for about an hour but the burning smell remained during operation. I am literally too nervous to turn on the projector in case this lamp assembly is causing damage. I expect this lamp to fail sometime in the near future. Which puts me out about $150 for two of the exact same lamps shipped from the exact same vendor, one of which failed within 5 minutes of installation.

I was really looking forward to this light.. I ordered and received on time, but light failed after 2 hours.... Out of 10 rows of light strings, 6 failed as well as the top plate light assemble.. So over 75% of light failed.. I emailed vendor for replacement, that's when the fun started.. They wanted me to take pictures of the light installed and turned on to prove it was defective. At which point I declined to comply, because I was not going to waste my time taking a picture and then attempting to email to vendor, that offers warranty and money back. I told them I wanted a replacement, I even offered to return the light first, but the vendor (poor English as well) wanted me to write and document what was the problem and then asked me to video it... Again, I declined and then asked for a refund... They would not refund unless I took picture and explained why it was not working so they could "improve their quality process" All this for a $12 LED was not worth the time. I then detailed their policy of refund and or exchange and told them I was going to contact Amazon for complaint, which I did and Amazon Customer Service immediately credited the full cost plus the shipping charge and told me to dispose of the light and they were extremely sorry I encountered such a negative experience with vendor.

I really don't think this vendor understands how American business and customer satisfaction correlates to satisfaction. This may be their normal procedure in Tiwan or PRC or Korea, but this is not how its done in America..

I would avoid, at all costs, this vendor or anything associated with the website that is associated with them. The customer service is extra poor and borderline criminal, bit again it just may be a cultural difference, but If they sell in USA, then they need to adjust.

I purchased this lamp as a replacement unit in anticipation of when my current projector lamp dies. The package arrived in good order and there wasn't any visual appearance of damage to the box. I placed the box into my theater equipment cabinet and waited for the current running lamp to go out. 4 months passed and little usage of our home theater, brought us to our planned extended family vacation. When we returned from our vacation, we began watching movies and put time on our theater projector. The image diminished and I replaced the lamp with the new one that I had purchased from this company. Installation is extremely simple as I've replaced this lamp before. I finished the less than 5 minute install and fired up the projector. Immediately, I discovered this lamp did not work. I uninstalled it and repositioned it back into the projector, it still failed to work. I immediately sent an email through Amazon to this seller and waited for a reply. No reply was ever sent back to me. I sent an email to Amazon stating I did not receive a reply as well as called Amazon customer service. The rep from Amazon said it was more than 30 days and there was nothing they could or would do about it and it was my fault for waiting so long. I explained the purchase as well as the time frame and that the "new" lamp I bought did not work, he replied that there was nothing that could be done. I can understand receiving a bad unit, it happens sometimes, however, being that I've been in customer service in the past for some of the biggest names in commercial history, I understand that without a customer, a company goes nowhere. Do a good deed and 5 people hear about it, do a bad deed and everyone hears about it. I want all potential buyers to know that this was a bad purchase and bad customer assistance went along with it. With this purchase being nearly 180.00 dollars, I would expect decent customer service, they failed, both Amazon and the seller. I didn't want my money back, just a unit that worked. Upon return receipt, they would have been able to see that the lamp wouldn't have burn in, (it was only on for approximately 1 and a half minutes),  yet, they chose to ignore a customer and failed to assist. I highly recommend not to buy from this company ever and choose to buy from someone else, don't get ripped off and receive poor customer assistance or even lack of assistance as I did, hopefully I can save one if not many others from a horrendous experience. Amazon should take note as well since they bought Zappos who has excellent customer service and treats their customers and employees extremely well. Again, use another seller. This was a complete $180.00 dollar failure.

Items arrived on-time and packaging was secure however one of the lamps has a short in the cord and I am working on how to replace that without too much hassle. So for now I give it the low rating based on quality.
I am appending my original review as the company did respond to resolve my issue very quickly and replaced the lamp. I have updated this from 2 stars to a 4 stars due to hassle factor. The items are not top of the line but do the job I in
tended them for.

I purchased two 8" tall lamps from another company, and they were exactly as described, well-packed, and included the bulbs. Then I ordered a larger one from Black Tai. I had read the pages and pages of reviews and knew there there would be a good chance that I would get less than what I paid for, but I wanted a specific size, and theirs was the best price for it. So I gambled, which was my mistake. As so many other buyers, my lamp was shorter than described, weighed less than promised, and did not include the light bulb that was mentioned in the list of inclusions. When I contacted Black Tai, I was told that "it must have lost weight due to the release of gases". Nearly 2 lbs of gases leaked out of a salt rock? REALLY? The bulb was not included either, but I was told that they haven't included the bulbs for several years due to breakage concerns. Too bad it never occurred to them to wrap the bulbs in bubble wrap and insert them in the cavity of the lamp as the other companies do. They did, however, reimburse me for the shorter height and offer to send a bulb. It's a gorgeous lamp, but I will buy elsewhere in the future so I get what I pay for.

One light shone 30 lumens as advertised.  The other barely shone at all; maybe 2 lumens at most - not enough to illuminate anything.  Customer service promptly sent me a replacement without any hassle.  But the replacement was just as weak and useless as the one in the first shipment.  The company willingly agreed to refund half my purchase price, which is exactly what I wanted at that point.  I've installed the first, bright light and it works good.  But their poor quality control will keep me from buying from them again.  2 defective products out of 3 is too many.  Five stars for their Customer Service - Zero stars for their quality.

Hello
I am like many other customers were looking to reduce cost of electricity and switched to those bulbs. They all did ok for about 5 months but then "started going down - one by one". I had to replace 7 out of 20 in 5.5 month and since that more bulbs are went down. The company rep was not surprised by my call, gave me RMA # and told me to ship it back defective lights without any problems ( I think it is very common problem as you can read from other reviews). There is 1 caveat that you have to pay for shipment back and that may add up to ~10-12$.
I personally do not have time calling company and keep up with exchanges , mailing back defective lights and spending additional money for exchange. So in summary this is a very low quality product and I would not recommend this for purchase by anybody.

I have owned two of these lamps, the first one lasted over a year before it quit working,  I thought it was just a fluke that it quit working so I order a second lamp.  The second lamp quit working after only three weeks.  Yes, I did check the bulbs, the problem seems to be with the circuit board located in the base.  The seller said that they had three other lamps that stop working in the same week that I called.  I did get a refund for the second lamp.  It is my belief that there is a manufacturing flaw in the circuit boards.  That is to bad because I really liked this lamp when it worked. If I could locate the manufacturer I would see if I could could get a replacement circuit board,

Purchased these to replace for a desk lamp.  They have lasted on average six weeks before needing a replacement.  I would rate these as some of the least reliable bulbs I have ever used... thank goodness I bought twelve.

The 2500 hour quality control / lifetime label makes me chuckle.  Perhaps my lamp time travels?!?!

There was a lamp that did not work out of the package. After a month there are 2 more of the bulbs that stopped working

Updated:  One of the two lights I purchased stopped working.  This light was barely used.  I contacted the seller and they denied to replace the item or refund my money.  They claimed 20,000 hours of life and I doubt I got 1000 out of it.

Very harsh lighting and not warm or yellow in the slightest. It says 2700k but it's not even close. They can't be used with chandeliers unless they have covers.

The vendor was great to work with. The product and accessories were not up to par (stream light or surefire). Just threw it away.

Ordered this light in September 2017, back when it was an entirely different model with a 4400 AH battery.  It worked great for a couple of weeks, then the battery would no longer hold a charge.  I wrote to the company, Sahara Sailor, and explained the problem.  They offered to sell me their new model, with a much smaller 2500 AH battery, for 1/2 price.  I asked them to send it at no charge, since I had paid full price for the original light and it failed very quickly.  They agreed and said they would send their new model at no charge.  I never heard another word.  No new light, nothing.  So, I would recommend buying another light from a company that might honor its promises.

I will update this review if I hear from the company or receive a new light.

Good price. One of the lamps had a factory defect, would not light. Called supplier it was replaced with no problem.
