    Ushio 10k 400w MH Question

    I replaced my two 400w Hamilton 14k bulbs with 2 Ushio 10k bulbs. I've had them runing for a couple of days now and the color seems quite odd. The bulbs make the color look greenish. Has anyone had a similar experience? How long for the bulbs to burn-in?
    Instead of my yellow tang looking yellow, he looks yellow-green.

    I think the color should normalize after about 2 weeks. However it will also take some time for your eyes to adjust going from a bluer 14k to a whiter 10k.
