JULLISON A19 LED Light Bulb, 14W, 1500 Lumens, 100W Equivalent, 3000K Warm White, CRI80+, Non-dimmable, E26 Base, UL-Listed(4-Pack)

These lamps are pretty good for actual lighting. I like the 100W equivalent and the 3000K appearance., until the failures from overheating. In an open globe bathroom fixture with the base up position, flickering occurred, when I attempted to remove the lamp it would spin but not come out. In a table lamp with the base down. Both applications on for longer than 3 hrs a day. These lamps will expand from heat and then start to malfunction. Estimated 2-3 months in the bathroom and approx 1 year in the table lamp. (warranty is 2 years)Both these lamps were replacements for compact fluorescent lamps which lasted for years in the same application.When I contacted Jullison they were polite and appreciative for the feed back. Then I sent them pictures of the failure and they were appreciative again. Then when I requested a full refund for 16 of the 20 Lamps I purchased, they replied"The A19 is complied with UL standard and FCC as well and produced exactly according to components listed in the UL report. By passing the UL, it means the product is safe to use in USA even it generates heat basically as of one of its characteristics.We confirm the quality of our A19 light bulbs. If you insist on the refunding, please kindly contact Amazon local customer service as we take FBA 100% for all our products.Please dont hesitate to contact us for any further question you may have."Best regards,EllisI'm having failures from overheating in several applications. The latest were in an open globe bathroom fixture with the base up position, lamp started flickering and when I attempted to remove it the lamp separated from the base transition piece and would spin but not come out. Eventually I was able to work it out of the fixture socket. Signs of overheating were present. Same situation occurred in a table lamp this time with the base down. Both applications are on for longer than 3 hours a day. These lamps will expand from heat and then start to malfunction. Estimated install time 2-3 months in the bathroom and approx 1 year for the table lamp. It is my observation that the materials used cannot handle the heat or wire leads to the base socket are not soldered but squeezed into place, over time this could become loose and the flickering occurs, possibly the cause of the overheating. Not sure which one is the cause and which one is the effect. If this flaw is corrected I would continue to use, as for now I'm having to use other lamps.

I've bought these twice now, not to replace bulbs but to put in more lamps. I haven't (knock wood) had to replace one yet, and I have one that I have used every day for about a year.I like LED bulbs much better than incandescent because of the lower energy use, longer life, cooler actual temperature, and wider range of color temperatures available. I like LED bulbs much better than compact fluorescents because the light just seems much cleaner and nicer.I like Jullison warm white bulbs because they're good value for money, and for two other reasons: one is the 1500 lumens (brighter than a lot of 100W equivalent bulbs) and the other is the 3000K color temperature, just a bit brighter and whiter than the more common 2700K while still very definitely a warm light.I use 4 of these bulbs in lamps to light an office with no windows, producing a soft, warm, welcoming environment, and I can see my clients relaxing when they step into the room. (I have two more I can turn on additionally if I want the room brighter, but I almost never do.)

I bought 2 boxes of 4 bulbs. They are very bright, great shade of light for any room. A floor lamp that takes 2 bulbs with 2 of these in it lights up the whole room unbelievably bright. But 5 of the 8 bulbs have some degree of buzzing, some louder than others, that varies from being constant while they're on to sometimes going off after being on a long time. 2 of them I can easily hear from 6 feet away, the others only closer. It's a bit concerning and a bit annoying. Low pitch buzzing.Other than that...- Size wise: they are a little smaller than a regular incandescent bulbs- Temperature wise: the top of the bulbs don't get hot, so you can easily unscrew them to swap a bulb even if still on. But watch out! The bottom part gets REALLY hot!!

So far so good... Placed two orders for packs of Jullison A19 LED bulbs and they arrived in short order. Whether they emit 1500 lumens or not I can't verify, but the bulbs shed significant enough light to my satisfaction. Be advised to test each bulb as soon as they arrive in case any does not work. As with many other items, only time will tell if they last for anywhere near as many years as the company claims. On the box the buyer is informed that the guarantee is for only two years, so my guess is they will need to be replaced within a few years rather than anywhere close to ten.

I bought about 10 of these two years ago. They now all seem to be failing, one at a time. I woul’ve expected longer lasting from an LED. Besides that, they were good while they lasted

Fantastic LED bulbs. Very bright with a very nice 3000k color rendition. I bought these Jullison bulbs along with the equivalent 14w bulbs from Great Eagle for comparison, and these Jullison bulbs had a much better color than the Great Eagle bulbs, even though they were both advertised as having 3000k temperatures and both were 100w equivalents. The Jullision package says CRI80+, whereas the Great Eagle bulb does not mention CRI at all, which is usually not a good sign. The Great Eagle bulb actually felt like it was 2700k, instead of the advertised 3000k. The Jullison bulbs also cost 20% less than the ones from Great Eagle.I liked the Jullison bulbs so much I ordered a second set the same day the first set arrived.
