Bioluz LED 100W LED Bulbs, Dimmable LED Light Bulbs, Natural White 4000K, A19 LED Light Bulb 1500 Lumen - 4 Pack

Ever since LED lights came to my notice about two years ago, I've been trying to find the perfect combination of features in one bulb - and finally found it in these!In the days of incandescent bulbs you just needed to know two things really, wattage and soft white or daylight white! That was pretty much it. But LED lights don't really use those terminologies even though they try to tell you the rough equivalents.It was in giving us the equivalents that I was getting more and more confused. Soft White turned out to be really a dull yellow, which is perfect for one room in our house. Daylight turned out to be super blue and harsh. And "bright" I was scared to try! If daylight was that bright, how much brighter would "bright" be, I wondered!And in featuring prominently wattage equivalents on the packaging instead of more prominently displaying the lumens - that was making it hard too to get exactly what I wanted.Anyway, skip to a year or two later and I finally figured out there is color temperature measured in kelvin and lumens for brightness that I should be focusing on.So, I knew I wanted dimmable bulbs with a maximum brightness of around 1600 lumens. The problem was in the color. I could find 3000K and 5000K bulbs in the store, but I saw no 4000K.The 3000K bulbs are very yellowish and they look gorgeous in our hallway. But they're just too dull for the other rooms. I wanted something like our old halogen lights which I always saw as a very "clean" white. So, I tried the 5000K bulbs and they were horrible! They made the rooms of our house look like something in the basement of a hospital! They were so harsh.I wanted to try something between 3000 & 5000K but just could never find it in the stores. So, finally I resorted to Amazon. I found these 4000K bulbs and just plugged them in and they were absolutely perfect!A very clean and neutral white. And very bright. They're just what we need for most of the rooms of our house. After finally figuring all this out I'm really amazed that 4000K bulbs aren't more readiliy available. They really do seem to have the best configuration for home indoor lighting.I've read some reviews here where people complained that they didn't last long. I can't speak for that yet - but if they don't last long, I'll be sure to post an update.

I bought these as an upgrade for my ceiling fan light. Way better light output and their low watt usage meets the requirements of my ceiling fan.

This is a very good LED lightbulb. The 4000k color is great for a work area. I installed these in my kitchen and I really like the light they produce. For non-work areas, though, I think a 3000k color temperature bulb would be better. I also like that they are rated for enclosed fixtures, such as my ceiling lights. They do dim well, but only down to about 10%. I have Leviton 6647-P0W dimmer switches. With other dimmable bulbs I have, they dim all the way to off, but not these Bioluz bulbs. Ten percent might sound like a lot, and it is, but these are 14 watt led bulbs, so they are VERY bright when at 100%, and 10% might still be too bright for some situations. So, keep that in mind when considering these.

When replacing incandescent lamps, using dimmable lamps allows for adjusting light intensity. Works great.

I was touring a model home and asked about their lighting. They told me they use neutral white light bulbs because they give off the best color and make everything look clean and neat. This is the second or third set of these bulbs I've purchased. They really make a difference!

Used for bedroom overhead lights. Plenty of light, appropriate color (4000K), and they dim properly. All is OK. No way to assess energy efficiency, except for the rating on the box, which is good.

I’m a little on the brighter side now. Thanks guys

These have become our goto all purpose lights. The price is good and so far all have been non-problematic.

Pour le sous sol. Très belle luminosité.

I bought these light bulbs for our home office and it's a good thing we have a dimmer because they are extremely bright. I installed 2 bulbs in the ceiling fixture of the room and we have to dim them down a bit otherwise it's too bright to be comfortable.
