aclimating lights

[reefer44]

I am switching from a 6,5k bulb to a 12k
do i need to aclimate the new lights even though it is the same wattage???

thats a very good question. I would suspect that everything in your tank will react differently to the new spectrum of lighting even though it is of the same wattage. IMO acclimation would be advisable.
