top left before was 590 and droped to 380
and middle right was 360 and dropped to 250
so approx 35% drop in par which seems a bit high but i expected a drop which im fine with, the new bulb was only an hour or so old so ill test it again in a few days maybe.

I had the same worry when I bought my Ushio 20ks... but ended up liking alot more than the 14k...
Tank looks awesome!
