I wasn't sure the intensity was as advertised but using my phone's front sensor I calculated 518lm at full bright on my dimmer, so I'm going to call it close enough. The "warm white" is just barely warm. Nowhere near as warm as the halogen bulbs these replaced, but I can buy the 3000K as close enough again. They look close to white when I look at them, but the cast light definitely has a warm tinge to it. They're supposed to be dimmable and I'm going to call that one.eh, sorta, technically, OK mSee full review
