Fluxtronics A19 ~ A21 LED Light Bulb, Dimmable, 100 Watt Equivalent, 1600 Lumens, 5000K Daylight, 15W = 100W Light Bulb, E26 Base LED Bulb, UL Listed, 5 Years Warranty, 4-Pack

I bought the 5000k, daylight temperature bulbs. They're a nice cool light that has a high CRI so color registers well to the eye. The color spectrum balance seems nice. They don't give off a violet or a yellow cast as some 5000k lights do and it doesn't seem like it's hard to see well when the light is on like lights with a low CRI index. I use them with a dimmer and they dim with a more broad rage than many of the other lights I've used. When I first turn on the light switch with these, they flash brightly for a fraction of a second right away and immediately trim to the dimmer setting when my dimmer is most of the way up or within 70% of the brightest setting. That doesn't bother me but it could bother some people. I hope this review is helpful.Edit: The bright flash upon switching the dimmed light to ‘on’ doesn’t happen anymore. I had these bulbs in the same fixture as another brand which ended up burning out and now these bulbs don’t flash brighter when turning on while dimmed. It turns out it was a problem with how the other brand of bulb was drawing too much initial current. These are great!

I have gone through a lot of LED bulbs for our kitchen, and found it very difficult to find dimmable bulbs with the color and brightness I want that work well and aren't noisy. So I consider these a find! These bulbs are instant on, with no flickering or buzzing noise whatsoever. The 3000k color is a nice white without any blue or peach/pink hue, which I would describe a soft white, but not warm white. I put these in our kitchen fixtures. We have two 3-light chandeliers over a large 5-1/2' x 8' island, and a 5-light chandelier over our table in the eat-in area, with all fixture pointing down. They are wonderfully bright when all the way up, which is preferable when cooking; and also dim perfectly to soften the light to whatever level wanted. Would buy more Fluxtronics led bulbs if they made more options, like different levels of brightness, 3-way, and non-dimmable.

I am lucky enough to have the ability to work from home from time to time and have a nice enough setup to do so. The one thing I have found was that I got almost too relaxed when doing so. Not that the quality of my work suffered, but that my energy levels weren't where I expected them to be. It turns out, I just needed a bit more light. I had been using soft white bulbs previously, but now that I've upgraded to these 100/1600/5000 bulbs, finding focus has come much easier for me. It's only been a week or so, but the difference is obvious and immediate.

I'm very pleased with these bulbs (100W equivalent, daylight, dimmable). I put 3 of them in a new kitchen ceiling light, with a dimmer, and on full power they really light up the room. On low power they serve as a night light - and no humming. These were the least expensive 100W dimmable LEDs I could find. Highly recommended.

I purchased these bulbs, since I had prior experience with Fluxtronics, 75watt equivalent, 3,000K color temperature LED bulbs. There was a different manufacturer I used to buy 75 watt equivalent LED bulbs from, but, they stopped manufacturing them. I like 3,000K color temperature, and use 75 watt equivalent in some lighting. Fluxtronics offered what I was looking for. Those bulbs worked as expected, proper color temperature, etc.I had a 100 watt equivalent LED bulb burn out. I was thinking of going with the same brand I had in there, that burnt out, but, I thought I'd try something new. I saw Fluxtronics has a 100 watt equivalent, 3,000k color temperature bulb, and that the bulb was in a, "Normal" light bulb size. I like that Fluxtronics provided a photo in the description, showing the measurements of the light bulb. Some 100 watt LED bulbs are housed in a bulkier size light bulb, which gives me issues with them fitting in some fixtures.Well, this 100 watt equivalent bulb is not bulky, it is a normal size bulb. The light is good, as is the color. I've only had a bulb in use for a month, but, so far, so good.

These are amazing. Super bright and dimmable. I've purchased other 14W dimmable LED bulbs several years ago and there is no comparison. The newer technology is so much better. They are brighter and actually dim without flickering at the lower settings. I can't speak to their longevity but I love them.Thanks Fluxtronics. These are the best bulbs I've tried so far.

Installed all four 100 W–equivalent 5K bulbs in a single overhead fixture, since their actual current draw is so low it was perfectly safe and within rating. These bulbs produce a rather brilliant white light and dim very nicely with a standard Lutron Caseta wall dimmer. No weird buzzing noises or sudden level cut off.UPDATE: NO WARRANTY SERVICE: One of the four bulbs used in this open fixture died entirely after ~15 months of intermittent use. Not unusual for LED bulbs, sadly. But I must crater my review to 1-star for now because (despite the promise of a 5-year 'no hassle' warranty), the seller Fluxtronics will not respond to any inquiry, whether multiple emails to various addresses from their website, or the on-site messaging, nor voice calls to the phone # on the carton. Essentially, they are not standing behind their warranty so far, after 4 months of trying on my part.

I ordered eight bulbs, and two of them were dead. I am concerned about this. I am sure they will make it right, but I can't buy with confidence with this failure rate. The company contacted me and refunded me for the two bulbs that failed. However, two more have since failed. So I am returning them all and finding another company to buy bulbs from.
