If you can't remember the last time you cleaned your lights today is a good day to do it

The dust I expected. The dead flies not so much. BIG flies somehow got between the heat sink. My Kessils seem to be much worse then the black box fixture I also have above my tank.

I believe July 2016 would have been the last time I cleaned them but could be wrong..

heh I have mine on a schedule to wipe the dust and salt creep once a month.

I cleaned mine a week ago, first time since I purchased them about 2 1/2 years ago. They looked the same as yours... I think I'm going to start looking at them about every six months!

Awesome PSA, @andrewkw! Any fans need maintaining and are often overlooked.
