Ordered and received on time. I installed the first bulb and noticed that the color (of the light) was more of a yellow, noticeably brighter than the other bulbs in the fixture. A few hours later I turned on the device, but the new lightbulb didn't light up. Upon inspection, the bulb inside became cloudy - a clear malfunction. I replaced it with a second bulb and noticed that the (light) color was much whiter than other existing bulbs. The lamp has been installed for over a month, no problems. Since then another bulb in the fixture has blown and I have replaced it with the third bulb in the pack. Has been working without problems for a few weeks. I contacted the seller about the first bulb that failed and was promptly refunded for one bulb with no issues. If the lamp continues to work I will definitely be buying it again - a pack of FOUR of these bulbs is only a little more than I would pay for ONE national brand bulb at a hardware store! love to save!
