## Customer Reviews

### ⭐⭐⭐⭐⭐ led bulbs LNW
*by L***W on January 17, 2025*

Glad to find these bulbs. They fit a stove hood I purchased 20 years ago but worked perfectly. So very bright for cooking area as well. They are quality LED bulbs and the price here was great over box stores.

### ⭐⭐⭐⭐⭐ Replaced GU10 120V 75W
*by C***S on September 6, 2024*

The lights in the title were very hot and using a lot of power. They heated up the dimmer switch! These new lights were recommended by the electrician and have been fantastic! We ordered the 10 pack to start. They install in the same 2 prong base. The dimmer switch is no longer hot. We still need to replace 6 more. There is no flicker and we have the bright, daylight white; WOW what a difference. We have 20 lights on this track.

### ⭐⭐⭐⭐⭐ Energy efficient and long lasting.
*by K***N on February 22, 2023*

I bought a ten pack in May of '20 to replace the 10 halogen 50w bulbs in some lighting. At 6w (advertised) each they are using 12% of the energy and just as bright as the ones that came with the light fixtures. The bulbs get warm, but not egg cooking hot like the old halogens.As of now, February '23 I have one bulb of the 10 that has started flickering occasionally. I don't know exact run time, but the set of five that needs one replaced is the fixture that gets more use than the other.They are plenty bright for their purpose as well, just as bright as the halogens.I'm impressed with the run time and energy use. I'm tempted to measure the actual power draw and compare to the advertised amount. Overall a good purchase, I'd recommend them.
