I was excited to try the Gruotvszak 100-watt bulb because of the high lumen output. The light is bright and clear, but the installation was a bit tricky for me due to its size. Make sure you measure your fixtures first! Once up, it did its job well.

Bulb arrived damaged
Unfortunately, my Gruotvszak bulb was cracked upon arrival. I was really looking forward to using it for my office, but now I have to return it. Customer service was helpful, but it's such a hassle to deal with a damaged item right out of the box.

Bright light for my shop!
I installed the Gruotvszak MP100 U bulb in my garage, and wow, it's super bright at 9200 lumens! The 4000K color temperature gives everything a nice, clear look. Definitely worth it for the price, and the dusk-to-dawn feature is a lifesaver since I often forget to turn lights on and off.

Not what I expected
I bought this bulb expecting it to be as bright as claimed. It’s alright, but the light quality seemed off compared to other bulbs I’ve used before. I guess the 4000K color just isn't my favorite. It works fine though, just not blown away.

Decent bulb, but some quirks
The Gruotvszak bulb works well as a dusk-to-dawn light for my outdoor space. However, I had a bit of trouble getting it to fit in my fixture since it’s a bit bulky. Once it was in, it performed great with bright light, just a few customer service hiccups along the way.
