Ukey UG4 LED Bulb 5Watt led Halogen Replacement 12V AC/DC 3000K Warm White Dimmable, led Replacement for Halogen Bulb 50W 10Pack (5)

brightness adequate. color warm. these bulbs are bulkier than the lower wattage units they replaced. (hence the good brightness) Check your dimensions before purchase. I put compatible dimmer in circuit. Ideally the bulbs would dim a little more but this is a minor complaint.

Bulbs worked fine but when compared to similar lumen value bulbs these were not as bright. Also I ultimately returned these bulbs because they were too large for the fixture I wanted to use them with.

I installed 12 of the 5 Watt version in our dimmer controlled dining room chandelier and initially had problems with bad flickering especially at full or near brightness and buzzing at various levels. My initial thought was: these are going back...However, after doing some web research, I decided to first try updating my old made-for-incandescent dimmer with a new one designed for LEDs - specifically "Lutron Diva C.L Dimmer Switch for Dimmable LED, Halogen and Incandescent Bulbs". After installing the new dimmer and adjusting it per instructions (this took some finessing), everything is now working well:- No visible flicker at any level- No detectible buzzing- Good range of brightness. High is very bright and lights up the whole area. Low is low enough for me though not as low as can be achieved by the initial halogen bulbs.As to longevity: we shall see. So for so good but I'll update this review if any failures occur sooner than expected.

For some reason these bulbs are not as bright as the original bulbs and same wattage.

I like that they are sealed in silicon for outdoor use.

I bought two sets of ten of these LEDs. These do not work with the Leviton 6674-P0W SureSlide Universal 150-Watt LED and CFL/600-Watt Incandescent Dimmer. They flicker like crazy with it. I replaced the Leviton switch with the ENERLITES Rêve Collection Lighted Decorator Switch, Paddle Light Switch with Locator Light, Matte Finish, Single Pole, 3 Wire (not a dimmable one). All fifteen of these Ukey LEDs still flickered with five of them being far worse than the other ten I tried. Moreover, these bulbs came in generic little boxes which did not have the color temperature indicated despite there being an area for it to be listed. They were definitely not warm white as I had ordered. Lastly, and I have not negatively rated the product because of this, Amazon shipped the item in an envelope that essentially crushed five of the ten in one of the packs I ordered. Why send bulbs in an envelope? Again, I did not ding the rating because of this but I mention it solely as an FYI.

At full brightness, they are quite bright and would likely be a good choice for someone looking for the brightest G4 LED option. However once dimmed, the light they give off takes on a more and more green tint which was not acceptable for use in a bathroom.They also required an LED specific transformer in order to not flicker. With the proper transformer they did dim with minimal flickering.

Excellent
