Time for new bulbs.

[FitoPharmer]

That is what I am planning on doing with all my new tanks. I am saving up old metal fixtures to use as heat sinks to save a few extra $$ as well. Doing a LED retrofit your self gives you so much more bang for the buck compared to anything but some of the Chinese fixtures. And in some cases i.e. modular led boards they are dead simple and super cheap to repair if something does fail down the road.
