Hyperikon GU10 LED Bulb Dimmable 6.5W=50W, 120V MR16 Light for Track Lighting, UL, Energy Star, Warm White, 6 Pack

I have been burning 200 watts in 4 halogens for my range hood until one quit. It was time to replace those hot, inefficient halogens with LEDs, so I got this set of 6. The first two were difficult to install, and the last two absolutely would NOT twist into the socket.Well, "exact replacements" usually never are, and these bulbs are no exception. Turns out the new LEDs are ever so slightly shorter than the old halogens and the pins would not go all the way into the socket because the front end of the bulb seats solidly on the opening in the range hood.Fortunately, the socket depth is adjustable. Unfortunately, you have to tear apart the whole range hood to get to the bracket screws to adjust them. Once I did, the bulbs twisted in with ease.Operationally, the LEDs are similar, but not identical, to the halogens. When you push the button on this range hood, the lights are brought up slowly. There are three level buttons, and moving from level to level or off is done by slowly dimming up or down. The LEDs do that pretty well, but are a little sluggish. And it's only noticeable when there's a halogen in the group for comparison. Now that all 4 are LEDs, you can't tell and it works well.Overall, I am very pleased, and I like the bulbs and the light produced.So if you can't get your bulbs twisted in, you may now have an idea of why.

I bought these to replace some IKEA brand GU10 lights. These produce more light and appear to be well made. If they're actually UL listed, that's a good sign of quality.The 2700k Hyperikon bulbs I bought produce nice quality light and dim well. I personally don't care about CRI index.The price of these can't be beat! They're 500% less expensive than units in my local brick and mortar, and 250% less expensive than the IKEA bulbs they replaced.6 of 14 IKEA lights burned out in 6 months. While I hope these last for years, they don't need to last very long at all to be a good value for the price.

Brightness is worse than exact same specification LED bulb I replaced. Response time is slow when switched on but I can live with that. When dimes to 20 pct they just turn off. I wouldn’t buy again. The two types (old and this one) are installed side by side so it’s easy to compare. When dimmed, the old bulb responds flawlessly and almost linearly while this drops suddenly goes dark

On initial use, I'm very happy with with these lights. I replaced another brand of "dimmer compatible" bulb that flickered when dimmed with these and no flicker. The color temperature is perfect. I have them side by side with incandescent halogen bulbs of 35 watts and these are brighter and have the color. I'll be buying more.

Perfect replacement for several burned out bulbs in kitchen ceiling fixtures. Color temp was consistent with halogens that they replaced, but these are definitely a fair bit brighter. Only other difference is that the fixtures they went in have relatively open sides so you see a little light bleed from the halogens through the side glass of the bulbs. These LED bulbs have solid sides so you don't get any light to the sides. It's a minor difference, but not a deal breaker.

These are GREAT LAMPS. Good light output, good distribution, great temperature/kelvins. Don’t hesitate to buy this lamp. I tried others and was forced to send them back because they burned out quick, flickered, uneven tone, etc... This is a very high quality lamp.

Had to order these for a light fixture in my kitchen as the ones that came with it only lasted a couple of years. Hopefully these bulbs will last as long as I've heard they should...13 years. They are very bright and a way better price then in the big box stores.

These bulbs are great! I tried two other brands which both seemed to have very misleading figures for brightness and/or color temperature. These seem to be spot on with their brightness, power usage and color temperature. The build quality is also quite good to the other bulbs I've seen.
