LED Retrofit Light Engine, 3-Inch, 5000K Super White, 10 Watt, Dimmable, Flush Ceiling Fixture LED Upgrade Panel, Energy Star Compliant, Commercial Grade, 90 CRI

I paid an electrician to install these in multiple flush mount fixtures. I bought various sizes to fit different diameter fixtures. The light is more uniform than the hot spots created by bulbs. The lumen output and light quality is good. I cannot comment on longevity, which is my big concern. I would not attempt to replace this myself, so if it dies it will be expensive to replace with professional help required. The electrician also had an issue with a couple of fixtures and the holes not lining up with this device, requiring a small modification for installation. Overall I am happy.

I’ve upgraded my previous 1-star review to 5-stars.Unit was described as 5.5”. Actual unit measures 6.75” at widest and 5.75” at the smallest. Maybe the circuit board inside the plastic and metal housing measures 5.5”, but this will NOT FIT into my application. I was trusting the 5.5” description. This will go back - but it didn’t!!!! See belowI contacted the vendor, and they told me that I could remove the circuit board and use it by itself. I did and it worked great. The performance of the unit is fantastic. The light is very bright and the dimmer in my old ceiling fan is compatible. The vendor support was very quick and saved the day!

Used this bulb to retrofit an old lamp that used high power halogen bulbs. After getting all the hardware that had been roasted and toasted by the high heat halogen out of the way - this bulb fit right (I measured VERY carefully before I ordered it) and was super easy to hook up. Light is bright and really responds well to my dimmer switch.

fits perfect in the ceiling fans, strong material and easy to install

I retrofitted one of the 300W halogen torchiere lamp with 4000K 28W light engine. Right is the LED light engine, and left is 300W halogen bulb.The brightness is 79% of the 300W halogen bulb. The room illuminance is 146 lux with LED, and was 184 lux with halogen. This engine is the brightest LED retrofit kit I could find in less than 8in diameter. I am satisfied with the luminance.The color look correct to 4000K. The halogen bulb is known as 3000K. The LED looks a little cooler. It takes an hour to get familiar to the new color. But it is still comfortable. Not harsh as an office.The product package includes common light fixture hardwares to attach the engine to a fixture. I used the included bracket and bolt, along with M4 nuts and washers I have.

Just the right fit for an overhead dome light in a bedroom.These are fairly easy to retrofit into most fixtures, but my particular fixture in this application was a little tricky to mount. Just took a lot of time, up side down against the ceiling. My arms got really tired.Other than that great kit, provides uniform lighting and is dimmable. The week before I bought this product, I put the light fixture on a new dimmer, so I could optimize this unit's effectiveness.Worked out great, happy with the results. Only give it 4 starts for now, will edit review in a year. Want to see if it holds up over time.Nice!

Brighter than the original. Easy to install, had to modify though. Took new led apart to get the led card out and install in my fan. Only 2 holes lined up and I had to drill hole through mount plates for the wires. I cut the connectors off the old led and spliced them to the new led. Took about 5 minutes, looks and works great.

This is one answer to the problem of dim ceiling fans. But don't count on it being simple to install. Perhaps there are a few fans that it will mount into without modification. But it won't with most. And if it won't then you will basically need to figure things out for yourself; the instructions are rudimentary.The unit does produce a bright light. And if you have assembled ceiling fans, have DIY electrical skills, and have the ability and tools to drill at least one hole through some metal part of your fan then installing it isn't too hard. Otherwise, hire an electrician.
