new bulbs need advice

I am changing my bulbs out for the first time. I was just wondering what everybody does about getting corals acclimated to new bulbs. For instance shorter light peroid or nothing at all. I am going from ushio 10k to aqua connect 14k. Any help would be appreciated

Thanks

Buy some window screening material and add a few (2-3) layers in between the tank and lights. Remove a layer every 3-5 days.

Reducing the photoperiod isn't very effective since the intensity of the new lights is more dnagerous then the duration that they're on.

From 10K to 14K you may not have any issues as 14K tend to have a lower par. New bublbs are usually 30 % brighter than one year old ones so you may just reduce your photoperiod by 30 % and increase it back 10% per week.
