I only used these for 7 weeks, but I found I personally do not care for the "look" of LED light. Otherwise these are virtually brand new and barely used plus I am including 4 new T5 bulbs including 4 Giesemann Aquapink and 4 ATI Coral + bulbs. You can find plenty of information on these units here:
