I recently received a Current USA Ramp Timer to test out with my Satellite+ and TrueLumen LED fixtures. The ramp timer is an inexpensive digital timer that plugs in-line to the LED fixture and provides On/Off capabilities as well as a sunrise/sunset option that gradually ramps the light up and down at the beginning and end of the cycle. It also features a nice large clock display that can be helpful if you don’t already have a clock in your fish room.
I initially tested the ramp timer on my Satellite+ LED fixture. The on/off capabilities work as expected with this fixture, however, the sunrise/sunset option has mixed results. When the LED fixture is set to full power modes, the sunrise/sunset feature works perfectly, gradually increasing and decreasing the brightness. I often program my Satellite+ to dim the output slightly. In this mode, at the lowest levels, the ramp timer causes repeated flickering, which can scare your fauna and be distracting. With the TrueLumen fixture, none of this flickering is present. You can see these results correspond to Current USA’s official supported fixture listing:
|Compatible LED Lights||Single Ramp Timer|
|Satellite+ LED Fixture||ON/OFF Only|
|Satellite LED Fixture||ON/OFF Only|
|TrueLumen Pro Kits||Yes|
|TrueLumen Pro Strips||Yes|
|TrueLumen Lunar Lights||Yes|
|Panorama Actinic Blue||Yes|
|Panorama Pro LED||Yes|
|Stunner LED Strips||Yes|
Ultimately, if you’re looking to add some nice effects to your existing Current USA light solution, the ramp timer can provide what you’re looking for. Just understand the limitations with the Satellite fixtures. Finally, see the video below for installation instructions to see how simple it is to hookup and use.
