Product Questions

This can be used for a waterbox peninsula 25 i want try to put one single light in the middle of the tank
Question by: Rodrigo on May 14, 2024, 1:04 PM
Yes, you would be able to use this on a peninsula tank, though there are a couple other pieces you will need. This product is just the arms for it, you will need to purchase a slide for each Radion light and used the track to go with it as well. I have them linked below!

Does this kit include cross piece going to vertical mount to opposite vertical mount?
Question by: Nick miller on May 27, 2017, 4:05 PM
The RMS light tracks are sold separately in various lengths depending on your tank size.


Have a great day!

Do these have to be mounted on the ends of the tank or can they be mounted on the back and hold the bar across?
Question by: Christina on May 17, 2017, 9:34 AM
The Multi-Light kit is designed to accept the track straight on, so the legs would need to be mounted on the ends of the tank.

Have a great day!

Will this fit over trim that has a "ledge"? I have a deep blue 40 gallon breeder I am looking to use Ecotech Radion system.
Question by: James Bender on Jan 21, 2017, 6:21 AM
Great question! These will absolutely fit over the rim of standard rimmed tanks! :-)

How many lights can you place on a RMS rail? I have a 72 inch 220 gallon aquarium and I have 6 gen 3 Radions to place over it. Will the 70.5 rail hold that many over my aquarium?
Question by: Roman on May 20, 2016, 2:00 PM
You could place quite a few! We would not recommend more than 5 realistically for space concerns.
