Installing these Ukey 4W bulbs was a breeze. I replaced my old 40W halogen bulbs in the kitchen, and the brightness is just right! They also save energy, which is a nice bonus.

Not as warm as expected
I was looking for a cozy warmth with the Ukey 2700K bulbs but found them a bit cooler than I liked. They work fine, just wish the color temp was closer to what I hoped for. Still a decent product overall.

Disappointed after a short time
I had high hopes for these Ukey LED bulbs, but one burned out after just a month. I really liked the light quality, but I’m worried about the longevity of this 10-pack. Not sure if I’d buy again.

Great replacement bulbs!
I switched out my old halogen bulbs for these Ukey 4W LED replacements, and I love the warm 2700K glow. They dim perfectly without any flicker, which is a huge plus in my living room. The 10-pack is a great deal, too!

Bright but not very durable
The Ukey LED bulbs emit a nice warm white light and are bright enough for my needs. Unfortunately, one of the bulbs stopped working after only a few weeks. I hope the rest last longer!
