I find it funny that during or after the break-in period the buld has shifted to a yellow tint and is not as bright as a new one. Then again maybe there are a 'few' Coralife bulbs in existence that do work properly.

I think I might change mine to Geisemann 13K - I have heard nothing but good comments on these bulbs.
