Susie and I visited the Imtra display and was impressed by the light quality of their LEDs. They have a couple which can be switched from warm white to red. There's a full fixture type and a halogen replacement type. The latter comes on defaulting to red and through a timed on-off sequence, switch to white. We may use one over the nav table, a pair over the galley, perhaps. We'll probably start with just one over nav and see if we like it. Since we plan heading to Mexico at the end of the summer, night vision becomes more important.
