E11 LED, All-New (102LEDs) E11 Led Bulbs, 8W 75W-100W Equivalent, 850 LM, Warm White 3000K, Dimmable,E11 Mini Candelabra Base, JD T3/T4 360 Degree Beam Angle for Indoor Decorative Lighting(4 Pack)

Overall, happy with these lights. Color is good. But it's not as bright as a 75 W halogen; I've attached a photo of these bulbs (on the left) versus a 75 W halogen (on the right); you can clearly see the difference in bringness. But I knew that before I bought them, as they're rated at "only" 850 lumens, while a 50 W halogen is around 950. They're also not as compact as a halogen, so if space is tight, these won't work.EDIT 6 Oct 2019:After about 18 months of use, the first one died. These have been used in a guest bathroom, which isn't used much, probably less than an hour per day. So that's under 1000 hours of use. Not impressed. Lowering rating from 4* to 3*

UPDATE: Unfortunately, these bulbs lasted only about 6 months before dying. Not one of them or two of them...ALL of them failed around 6 months after installation. Looks very much like the internal power supply failed. LIghts started to flicker and then get dimmer and dimmer over a short period of time. Very disappointed in this product.Over the past few years, I have replaced about 90% of my indoor and outdoor lighting with LED replacements. What I learned is that you have to be careful with brightness and color temperature. I was concerned that these bulbs would not match my existing 75w E11 halogen lights. I have to say that I was pleasantly surprised. Both color and brightness were a close enough match to declare victory. These are replacing three 75 watt lights in outdoor fixtures (waterproof) that are lit 5 hours/night on average. Based on my electricity cost, this will save me almost $100/YEAR in electrical cost (201 watts saved * 5 hrs/night*365 days/year *$0.27612/1000 $/kwh = $101.28 saved/year). I live in the san francisco bay area, and as you can see, electricity is not cheap. Another benefit was that I was replacing bulbs every 4 or 5 months (cheap bulbs running very hot had horrible lifetimes), so that was another let's say $9 * 3 times/year=$27.

The bulbs do work great with a regular switch but don't work with a dimmer switch which was posted in the description for this item.

Good color of light and they put out a lot of light, but they flicker when they're dimmed...

I ordered these because the price was so good for 4 bulbs. However, none of them worked when I installed them in the ceiling fan--although the halogen bulbs in the fans were working just fine. I thought I received a bad box, so I returned them to Amazon and requested they be replaced with the same product. Two days later, the new package of bulbs arrived and again all 4 bulbs were defective. Don't waste your money on this product.

Of the 4 bulbs shipped, one had a wrong thread, two bulbs light output was no better than a night light, the fourth bulb light output was about a 40 W (tungsten). The product description: 75W-100W Equivalent, 850 LM was completely inaccurate. Amazon should enforce a quality control and a truth in advertising.

I ordered two boxes of these lights. One of the boxes is mislabeled and the light base is to large to fit the fixture. The other box of lights was fine.

Unfortnately, not one bulb worked. I only needed 2 but not one bulb lit. Fortunately, my halogen bulbs are still working so not a big deal. I guess I'll wait another year or so to see if the bulb manufacturers can make improvements on this style. (E11 base, JD mini can light.)
