12х LED assembly for reef tank v4.4R
 
Version 4.4R Product code: 12xV4.4R

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



 
  $27.00

Availability:  Out of Stock

The new LED assembly is now completed and ready for sale. The pictures of the installed LEDs will be available after the Chinese New Year holidays, i.e. after 9 February 2017.

Differences from Rev. 12xV4.3R
1. The Neutral White LEDs now gets a separate control channel. Thus, more precision control of the critically important part of the spectrum is now available. Also the LED assembly now has 7-channels.  
2. The Violet channel now consists of 3 different LED types. This change extends the spectrum coverage much more. 
3. The true Blue LED is installed now. The dominant wavelength of this LED is 475-480 nm.
4.  The Blue and the Turquoise LEDs are now covered by the newest Luxeon C color. Please find out more details in a datasheet to the LED assembly description.
5. The MCPCB now has a better thermal conductivity.
6. We use the immersion gold-plating of the pads MCPCB with chemically precipitated nickel sublayer (ENIG) this helps to provide the best quality and reliability of the soldering.  
7. The most stable against UV radiation solder mask Taiyo PSR-4000 LEW7S with best whiteness.
8. Now we use 8-pin connector to make connecting easier and more reliable. 
Despite to all the technical improvements - the price remains the same!

Features:

  • Full-spectrum
  • Small dimensions (size is determined by secondary optics)
  • 10 power LEDs, C35 generation by Semileds
  • 2 newest LEDs Luxeon C color
  • 9 LED types combined in 7 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
