Genitronics Otronics Dimmable GU10 Led Bulb,Spot Light,(50W Equivalent) 6.5W,500 Lumen,Daylight White(4000K), 40°Beam Angle,CRI>83,120Volt,UL-Listed,6-Pack

Very bright and focused beam of high-quality and high-CRI daylight-quality light. We are pleased with our purchase and hope that they last as long as advertised.Dimming is efficient and there is no buzz from either the bulbs or the dimmer. We are using Lutron Maestro MACL-153M-WH White Multi-Location CFL and LED digital dimmers with six bulbs per circuit. If you are using fewer than three bulbs per circuit, look for a different dimmer with a neutral (white) connection as the Lutron requires constant power through the circuit to power itself and the dimmer's LEDs. This may leave your LED bulbs on all the time, even when switched off, at a very low level.

These were packaged nicely. The light is bright with almost no heat at all. They dim, but they do not dim very much. Still a lot of light at the lowest dim setting.

I purchase these GU10 daylights led bulbs to replace my old halogens bulbs in my basement. The quality is very sturdy, and it fits in the socket without any issues. I have them installed for about one month now, the light quality is still the same it hasn’t change color or fade like some other brand I bought before. I also tested different setting on my dimmer switch and it works great no noise on the lowest setting. I would purchase again without hesitation.• Color Daylight 4000K• 6 Pack• True Dimmable Led

These are advertised to be 4000K and 500 lumens. They are more like 2700K since they are a dull yellowish color and they aren't very bright.I am using them to fill in where some older, similar lights are beginning to die. However, the ones that are still working (4000K and 500 lumens) are much whiter and MUCH brighter than these new ones from Genitronics.I am going to return these and look for another brand.

I got these LED light bulbs to replace the existing light bulbs, the LED bulbs look good. After the installation, the lights work great. I will definitely buy these again if need.

I bought these bulbs for the hood above my stove. It has a two-position switch, high and low. I figured since they were advertised as dimmable, they should work. They work on high power, but on the lower power switch, the bulbs just do a strobe-light effect, which is kind of distracting for cooking.The light looks great, but I won't be using the lower power for a long time!

Bright, perfect color temperature, fairly wide spotlight. We are using these to light a room and are now able to cover the whole room unlike the halogens that came with the light fixtures.

I received a completely empty envelope without anything inside. I'd say that's a disappointing $17. Hard to give anything more than 1 star. Wish I could give zero stars for receiving nothing and paying the money.
