An Ikea LEDARE 400 lumen LED bulb beside an Ikea RYET 400 lumen LED and a RYET 600 lumen LED. Supposedly, the LEDARE was dimmable while the RYET was not, according to the Ikea website, but I didn't have any dimmable fixtures to test them on. Ikea LEDARE and RYET bulbs purchased in 2016. Maybe I got a bad batch, but the 600 lm RYET bulbs from at least two packs made a buzzing sound that was audible from a few feet away. The LEDARE and RYET 400 lm were dead quiet.
