12х LED assembly for reef tank v4.1R
 
Version 4.1R Product code: 12xV4.1R

The 12xV4.1R LED assembly is an economy light source for your reef tank. Its creation was the outcome of years of research, as outlined in our article
Light in the Reef Aquaria

Differences from Rev. 12xV4.0R.
1. The LED chains are now connected between X1 and X2. As a result, the LED assemblies can be easily connected in series. This simplifies the assembly of a LED fixture, especially when using our 2x LED drivers with a high voltage power supply: up to 5 LED assemblies can be connected in series. 

2. An MCPCB with improved thermal path has been used. The LEDs can now be used at their maximum current.

3. Significantly increased quantity of emitted radiation of all types of LEDs, excluding the Blue LED.

The LED assembly must be used with matching LED drivers. If using with ReedLedLab controller and drivers, control channels on the drivers can be configured by jumpers. Instructions.

 

Features:

  • Full-spectrum
  • Small dimensions (size is determined by secondary optics)
  • 12 power LEDs, Latest C35 generation by Semileds
  • 8 LED types combined in 6 independent channels, to provide unique control over spectrum
  • Sufficient radiation in true violet range, to provide for best coloration, fluorescence, and coral growth*
  • Minimized “Disco effect”, due to densely populated LEDs and the use of hybrid secondary optics with diffusers
  • A completely solderless solution simplifies the assembly
  • 100% quality control for all LEDs on the assembly
