Question: What is the manufactures warranty on this light?
Document: There's lots to like with this LED lamp; it's quite compact, has a decent light and it's priced reasonably, but it also has some shortfalls. While it's described as a warm white, it seemed more bright white to me, while it's claimed to last 40,000 hours, the actual warranty is 3 years and for me the worst of all, it has labeling on the top of the bulb.
The one LED bulb mixed with the more yellow/pink incandescents were just not going to work, it was freaky having the varying color light over everything. So, we bought more cool LEDs. Now all the slots are filled with HitLight Cool LEDs, and it's a huge improvement. They have not burned out, nothing is flickering, everything is pretty well lit, I'm  darned happy with these so far. If they last as long as the warranty touts, I'll be a very happy camper.
I have bought 18 of these bulbs, and have installed them in 2 ceiling fans, light over my dining room table, and in the bathroom. It puts out a nice white 6000K light, not the 3000K yellow light. They are nice and bright and have done everything as expected. I have not had any failures over the last month that they have been put into use. With the great warranty and no hassle with Amazon, Im not worried about failures or getting my money back!
There was no notation in the description indicating if this product was dimmable or not. It is not dimmable. I will use these elsewhere but they are not suitable for my purpose. I wish manufactures would be explicit.
It's clear that the seller doesn't want to &#34;encourage&#34; buyers to execute the warranty.I think that LED bulbs are the future, and I'll try them again but from a different seller.
We're used to incandescent bulbs and we always try to get that same tone when buying alternate CFL or LED bulbs. The strange thing is, it seems different manufactures claim different things.
Perhaps if I had used two LED bulbs in the fixture, the bulb would have lasted longer. I didn't find a warning about this in the seller's description.The bulb has a three year warranty, but I couldn't find anywhere on the Amazon site anything more about that, just the claim that there was a warranty. I guess that I could try to return the bulb to Amazon (after 6 months?
company imports as all do from China and you have to be careful about wattage and color temperature. You need about 2500k for something that looks like an incandescent bulb. They don't sell a high enough output bulb to be of much use to the consumer except where you use low wattage bulbs now. Also the headline says it lasts 10 years but if you read the warranty its only good for 3 and it might be prorated.
I just wanted to point that out in case anyone thought that might be the issue for the early issues.I ordered a replacement bulb off of Amazon because I wanted to see if there was a warranty and I didn't have any of the original boxes. The box indicates that there is a 3 year warranty so now I'm debating if I want to try to deal with customer service to see if they'll replace any of the bulbs.
This math includes the cost of upgrading by buying the new bulbs. Also based on about 10 hours of use per day, and a 60W price of $17 and 40W price of $10. If you use it less than 8 hours per day, it still reaches break even in under 2 years, plus the bulbs come with a 2-3 year warranty, and are rated for about 9 years of use for most people.
Answer: yes
