LUNO A21 Dimmable LED Bulb, 15W (100W Equivalent), 1600 Lumens, 2700K (Soft White), Medium Base (E26), UL Certified (4-Pack)

Cheaper to run and don't generate nearly as much heat. One of my light fixtures is rated for 60w max, but with these I can run the equivalent of 300w. without tripping the fixture's thermal limiter. Let there be light!

EDIT 2: Luno Lighting confirmed my order and is sending a replacement 4-pack at no cost to me. Once installed, I will see if the replacements hold up better than the horrible first 4-pack I received. Luno says I may have received a bad batch. I did not have to go through the warranty claim process outlined on their site. I encourage anyone else who received a bad set to contact the company about a replacement. The percentage of 1-star reviews, combined with the high percentage of 5-star, makes me think that I may not be the only person who received a bad batch. Good news, if you do get a "bad batch," you can contact Luno for a replacement without much hassle. I'll report back on the life of the new bulbs. If they make it to 6 months, they will have already doubled the life of the original purchase. ORIGINAL REVIEW BELOW: Absolute garbage. Two of the bulbs in the four pack failed 3 months after purchase, after starting to flicker at the lower and upper end of the dimmer range. Those two failed within a week of one another. Installed the second set, began flickering 3 months later, and the third bulb failed completely today, six months after purchase. The fourth is flickering and will die soon. These were in a dining room, used about 3-4 hours per night, 7 nights per week. The package states that they have a 25,000 hour life. Assuming 8 hours a day (very generous) EVERY day of the week you get 1,400 hours, or about 6% of stated life. Absolute garbage. Will never buy Luno bulbs again. Found the site, lunolighting.com. Here's what you have to go through to get a warranty on a bulb (hint: not worth it): "• details of the failed Products; and for System warranties also details of other components used; • installation date and invoice date; • detailed problem description, number and % of failures date-code of failure; • application, hours burned and number of switching cycles; Where a warranty claim is justified, LUNO will pay for freight expenses. LUNO may charge Customer for returned Products that are not found to be defective or non-conforming together with the freight, testing and handling costs associated therewith."

I have ordered quite a few 60 & 75 watt equivalent bulbs but they are just not bright enough for some areas of the house. So when I saw these 100 watt equivalent dimmable bulbs, I decided to give them a try. I found that they are significantly brighter than the 60 & 75 watt bulbs. I'm determined not to purchase any more non-dimmable bulbs because most of the lights in my house are on dimmers. So overall, I am very pleased with these dimmable bulbs and will be ordering more in the future.

So far so good. Nice light distribution and quality. Quite bright, too, which is what I was looking for. I don't know about long-term use yet. If any fail, I will update the review later. 5 stars. UPDATE: Unreal. 2 days after I posted my 5 star review, one of the bulbs failed. It started flickering, then died. It was a bulb in a closet fixture that had only been "on" about a minute a day for a few months, not even a dimmer. Very disappointed now to have a 25% failure rate. Will now examine warranty... but if they requiring mailing a bulb to them, it won't be worth it. Lowering rating to 3 stars and will update review with info about what happens next... Lowering to 3 stars. UPDATE 2: Well, I went to their website and sent them a message about the failure to see what I am supposed to do. Waited a few days and got no Email or response. But then I suddenly had a package in my mailbox. In the box was a single, correct, working replacement bulb. Oddly, it had no paperwork or anything nor, apparently, I am supposed to send them the dead bulb. So, although there was zero communication, they stood behind their warranty! Upgrading to 4 stars.

Very bright bulbs, they get warm I would recommend open fixtures only. So far 2 started to flicker and stop working after 10 months. Overall bright, energy efficient but not long lasting

I haven't been been using these bulbs for very long, but I do regularly turn on two of them I have installed in table lamps that I converted to dimmable sockets. These Luno bulbs are everything I hoped they would be. The dimming action is very comparable to some 60W dimmable LED bulbs from a different manufacturer that I previously installed in my ceiling lights. I'd buy these Luno bulbs again.

Bulbs arrived on time and well packed. Good size to fit our fixture, and the dimming feature works well. One bulb died after about 18 months- too short of a lifetime for the price paid for an LED bulb that should last many years. I am now reluctant to order this same make and model, but will find a comparable blub from another maker & vendor to replace this failed one.

I learned a lot from buying these bulbs. They were too tall for the lamps I bought them for, so I researched what A21 meant and learned that A19 bulbs would be better for me, so I bought those too and found other uses for these. The 2700k color looks best for my rooms and paint colors, and the yellow light doesn't hurt my eyes like 3000-5000k bulbs do.

The dimmable feature works well, although there is residual light at the lowest setting which may be due to the old dimmer I am using. One bulb burned out and they quickly gave me credit towards new ones excellent service
