Pros: 3 year warranty, but see Other

Cons: Very short lived - did not last as long as an incandescent bulb in the same fixture
Cool white is not suitable in many locations

Other Thoughts: I put these in a very difficult to reach ceiling fan in a vaulted ceiling, so I would not have to change them very often. They were more difficult to install and did not last as long as the incandescent lights they replaced. Within a two year time period, I had to replace three out of four of them. I should have sent them back since they are still under warranty, but when I considered the hassle and costs of shipping, I just opted not to bother. I do not plan to purchase LED bulbs from SunSun in the future.

Pros: Heavy duty Big heat sink
Very Bright Love the color

Cons: Only lasted less than a Year 50,000 hours Never???????
Flicker Flicker Flicker!! After a year they turn in to strobe lights????????????

Other Thoughts: Of the six that I bought at $9.99 a piece all different times the only 2 that still work are outside on motion detectors.
The 2 in the living room ceiling fan all dead (flicker) and the 2 in bathroom dead (flicker) after less than a year????????

Pros: Bright, reliable, efficient,

Cons: None

Other Thoughts: I purchased a few of these bulbs over eleven and a half months ago, and have had no problems with them, whatsoever. They are just as brilliant as they were the day of purchase, and I am actually about to order another set to replace some older bulbs in other rooms. I have been very satisfied with these bulbs.

Pros: Nice bright energy efficient.

Cons: Died and no warranty replacement or refund.

Other Thoughts: They are ok as advertised, just be aware if your bulb dies the money is gone.

Pros: when it works they are great!

Cons: one bulb burnt out after 6 months and another after a year and a half customer service was useless!

Pros: I got these for the bright white color.

Cons: Died after 1 year and cannot find any warranty information other than a contact us that hasn't been replied to. Apparently there is not warranty even though it says it's 3 years.

Pros: When they work they are fine. I purchased 5 of these and just over a year later 2 of them are dead. I contacted the manufacturer and they don't even bother to respond. Be aware you have no warranty on this product. The 3 year warranty is non-existent.

Cons: Don't last

Other Thoughts: no warranty

Pros: They work. I bought 3 of these from another seller about 1 year ago and they are still going strong. Those that are having failure problems might have them in an enclosure where heat can build up. That will make them fail. Don't know, I just know mine work well and still work. I'm about to order a couple more right now. Not really a bad price with the promo.

Cons: You really can't put these in an enclosure like ceiling fixtures, etc. cause they will get really hot, failure hot. They need to be in the open. Funny that something that uses such low voltage can generate such high heat.

Other Thoughts: I have a friend that bought well known name brand led bulbs and put them in ceiling fixtures that were on at least 4 hours every night. None of them lasted more than 6 months. Remember, HEAT KILLS!

Pros: Nice light and uses less than 10 watts.

Cons: Don't last long, one has already quit working and it is only
6 months and for 3 of those months I was out of the country.

Pros: It's great when it worked.

Cons: The claim about sunsun bulb longevity is greatly exagorated. It is likely be based on a life expectancy of LED device all by itself. One has to remember that the actual LED bulb needs a substantial amount of other supporting electronic devices, and these, in my opinion the cause of failure. Surely, SunSun doesn't manufacture neither LED's nor other components. They acquire components and assemble them into a bulb. And the components don't last.

I got a couple of these in the middle of November 2013. One of them sopped working sometime in the end of January 2014, a little more than 2 months of moderate use. Got a replacement from NewEgg. The other one ceased to work in the end of May 2014, just over half a year from the time of purchase. For comparison, I have a couple of CFL bulbs used in the same kitchen/dining area and used about as much per day as SunSun LEDs. The CFLs were installed long before the SunSun and are still working.

This time I tried to replace the 2nd broken LED bulb with SUNSun itself. They asked me a lot of details and documents and then said they are out of these for a while but should be getting soon. I still didn't get anything from them. In any case, it's just not worth the hassle.

I will give a try to a different brand.
