In 2013 I bought an Ikea lamp that uses three 3.5W 50mA LEDs with an E-17 base. All of the Ikea lightbulbs have worked perfectly after 7 years of use but they weren't as bright as I wanted so I bought these 6w bulbs. Received the 6w bulbs on 1/24/20, installed three of the four bulbs on 1/24/20 and have been very happy with the extra light output. However, on 03/16/20, after less than 2 months of use, one of the new bulbs burned out. I wrote and inserted the installation date 3/16/20 on the fourth bulb. A little over 2 months later on 05/26/20 the lightbulb installed on 03/16/20 burned out. Now I have two 6 watt bulbs left. Another bulb burned out at 6-4-20, which I put on 1-24-20. At the moment I only have one working lightbulb that was installed on 01/24/20. I give these lights 5 stars for brightness and zero stars for durability and value. Garbage.
