Sirius XTC

A Full Spectrum LED Light designed and Made in the USA for the serious Reef Keeper.

Product Description

Sirius XTC 


  • Spectrum optimized for coral growth and color rendition.
  • Housing optimized for maximum thermal efficiency both active AND passive.
  • Controls allow for full dimmability down to 0% with the Max Intensity (PAR) of a 400 watt MH equivalent.
  • Our LEDs are specifically binned for optimal performance and tunability.
  • Over 600 PAR @ 24″ and over 2600 PAR at 12″
  •  Super quiet fans with Temperature Overwatch and TSC Temperature Sensitive Control
  • Temperature values are hard-coded in the firmware. Fans may fail due to salt creep or excessive humidity.
  • The XTC protects itself in the following manor…If the temperature exceeds 60C (140F)–LEDs dim to 15% of their original brightness–Fans are powered to maximum.-This level is sustained until temperature drops below 50C (122F), then normal operation resume.
  • Optics are optimized for penetration while limiting that nuisance spill of light.
  • 2,700 K to 20,000 K depending on intensity setting and LED array combinations.
  • Perfect for SPS, Clams, LPS, and most importantly, YOU!

Maximum coverage 36×36 for softies and low light corals when hung 42″ over the sand bed with ripple wide optics.

Wide angle reflectors are available for applications close to the water surface and penetration is 24″ or less is required.



Primary Binned LEDs w European Optics

Supplemental Spectrum LEDs arranged in seven clusters of three with each color having its own dedicated channel for ULTIMATE COLOR CONTROL!

Based on our research, documented and supported by numerous Marine Biologists, our  Primary Binned LEDs, offer optimal growth.
