Review: Good for translucent fixtures, much cheaper than Philips - I have these Hampton Bay light fixtures (model 626368) where the middle part is frosted glass, so I need bulbs that emit some light out the sides, not just the front. That's why I've been sticking with inefficient halogens for so long: until recently, LED GU10s could only shine light out the front, like spotlights. This bulb has a glass casing like older halogen and incandescent GU10s, so it emits some light from the sides in addition to the front. Finally, a cheap LED bulb that is suitable for use in my fixtures! I'd previously used the Philips 465054, which also lights up the sides of the fixtures. See photo #1 for a comparison of this bulb with the Philips: the Mastery Mart bulb is on the left, and the Philips is on the right. Here are some differences I've noted: PROS: * Much cheaper, easy to buy in bulk CONS: * Light out the sides is dimmer than with the Philips 465054s * When looking through the side of the frosted glass fixture, there's a green-ish spot in the middle of the bulb, which is not present with the Philips 465054s. See photo #2 for an example. MATTERS OF TASTE: * This bulb's beam angle is wider, about 40 degrees as opposed to Philips's 35 degrees. * This bulb's 2700K color temp gives more of an orange hue than the Philips 465054 at 3000K; my wife finds this bulb's orange-ish color more pleasing for our home. It's still whiter than any of my old halogens or incandescents.
Review: Dimmable LEDs with decent backlighting - If you're have track lights with glass shades and you're looking for LED bulbs that match the backlighting of halogen bulbs, good luck! For most LED bulbs in this style, backlighting is non-existent. These bulbs give off enough backlight to light up the shades, which is one of the main criteria I was searching for in an LED replacement. In addition to that, they are dimmable and have a pleasing warm color. At full brightness they are very bright, and they have a wide dimmable range before they start to flicker. I've also reviewed the Phillips GU10 LEDs and I find that these are slightly warmer, slightly brighter, and have just a bit more backlight. I wouldn't say that the Phillips are on the daylight side of the light spectrum, but they are very neutral in color compared to the warmth of these bulbs. I like these better, but they're not so different that I'm going to replace the Phillips LEDs with these.

### ⭐⭐⭐⭐⭐ Good Efficient replacement for Halogens
*by W***N on October 17, 2018*

Replaced 50W Halogen bulbs with these. I was worried that the light would feel too different but there was no need to worry. The color listed as 2700K and that is how it feels to me when I compare it to different LEDs that I have. The lights are very bright when at full power. They dim very well without any noise. The only small issue I have is with dimming. They don't dim down to 0% which would have been nice. But that is a minor nitpick. They dim down to about 20%. The beam is diffused and not a spotlight. My bulbs are overhead at 6 foot intervals and the lights all blend together. I can't speak to their longevity yet, but they seem well made and I am very happy with these.
