These are exceptional 75w Dimmable Filament Bulbs; Very few 75W dimmable lamps are currently available. I replaced the Costco 50W bulbs. eight 4" ceiling lights in a circle in the living room. The room has always looked like a cave. But when installing these lamps we went from late evening light to daylight! Of course we added 200 watts of light output. But the fact that these weak I doubt we will ever run lamps at their former optimum wattage of 400 watts and leave them at 600 watts They were dispatched in two days and well packaged and I doubt they could break due to the high build quality the first photo is 75w x 8 lamps or 600w the second photo is dimmed by around 400w my wife and i love these lamps.
