The new Aqua Medic Oceanlight kicks the crap out of both of them IMO. It has cooling fans, built in moonlights (which the TEK does not). The splash screen is a three piece glass which is really easy to remove and clean and does not warp like the TEK one has a tendency to do. The Aqua Medic comes with both mounting legs and hanging kit, with the TEK you have to buy both and the Aquaticlife comes with legs only. The build quality of the Aquaticlife and Aqua Medic are both very rugged, they are both better than the TEK. Aqua Medic includes bulbs for less than the price of either one of the other fixtures.
I just finished researching the heck out of the newest T5 fixtures for the best light for the buck and I did settle on Aqua Medic because the new Oceanlight that was released about a month ago has everything a person could want in a T5 HO hands down.
Again just my humble opinion.
