Review on Brilliantly Bright Daylight Non Dimmable Bulbs - 12 Pack, 1200Lm by David Fisher

Just received, 2 of them were missing the contact on the underside of the bulb. The photo also shows a nice lightbulb so you can see what I'm talking about. Found contacts at the bottom of the box. Appears to be about half the weight of other equivalent 75W bulbs. Cheap electronics? Can't find a way to contact the manufacturer. You may have to return the entire box. Color (brightness) seems correct
