Question

Changed light bulbs in chandelier-style ceiling fixture and only two work out of eight. I bought two packs of GE Reveal B10, 40W candelabra bulbs. I'm not sure what type of bulbs were in there before but suffice it to say that the wattage is the same. I wanted that clean, beautiful light touted on the package, but the bulbs won't work. I put the other older bulbs back in and they work fine. I've even switched out the working GE bulbs with other GE bulbs to rule out whether they might be defective, but they worked in the socket.
