Review on GMY 4Pack Candelabra Dimmable Halogen: Enhance Your Space With Effortless Ambience by Terry Murphy

They are quite bright for their size. I bought a 4 piece 100 watt unit to use in my living room. I bought them in March and put in my last bulb in December. So basically I've lived with 3 bulbs for 8 months, which means they each have a lifespan of just over 3 months. The living room is the only place these bulbs are used and none of the others I use have had to be changed as often. I'll have to order elsewhere to see if it's just the nature of lamps of this size or if it's a branding issue.
