Also, that particular MR16 is 4000K, which would appear blueish at night. You ideally want 2700K (halogen's native white point) with a high CRI. Even 3000K is a bit on the odd side. For example, I replaced some T4 halogen bulbs in our landscape lighting with these things, in "warm white" (which they define as 3000K-3500K), and they do the job but aren't nearly as pleasant as the original halogens.
