My mom wants me to light a piece of artwork over her fireplace. I'm going to change out her existing Juno TC2 can trim from a 25W WH to a low voltage MR16. I don't know how bright I want this which got me thinking: if I put a 50watt MR16 and dim it, will that make it yellower than if I put in a 20watt MR16 without a dimmer. Something's telling me I'd be better off sizing the wattage without a dimmer rather than putting in the largest and just dimming it. Any other thoughts?
