Yes, I would recommend this.


Pros: Perfect stable design

Cons: none

The mount feels very stable and is easy to adjust. Took about 5 minutes to put it together and mount the light. Superior to comparable products.

No, I would not recommend this.

Doesn't work for a regular tank

Pros: Nicely packaged, great cord control

I could not get this mount to give me a warm and fuzzy feeling dangling a heavy light over the tank. With a standard nothing special tank with a plastic rim, I couldn't get this mount to stay firm in place. Even after removing the plastic in the mounting area it still trys to fall into the tank. If the bracket were reversed to where the longer portion was in the tank it would work. I am currently working on other options to setting up the RL50 LED.
