  • Over 600 PAR @ 24″ and over 2600 PAR at 12″
  •  Super quiet fans with Temperature Overwatch and TSC Temperature Sensitive Control
  • 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 10,000 K depending on intensity setting and LED array combinations.
  • Perfect for growing plants indoors without the heat or electrical consumption.

    Very satisfied with the Sirius XTC Hydroponic. I have not spoke with anyone who used these lights for this purpose but after sending a 1000 questions to reefledlights I decided to give it a shot. I couldn’t believe I pulled over 10 Oz with two plants last grow, and am looking at that much or more this grow with just one plant. I have learned that you can get more bud with just one plant with the right light, if you train / top / firm the right amount of times. You don’t need to grow 3 or 4 plants to get a pound, and you don’t need a large Tent. Right now I am in a 9 sq ft tent, but am getting a 6 1/2 sq ft later this week. That way there will be more light in a smaller amount of space, and the buds will get even bigger. I am thinking about ordering the 2 XTC kits since I really don’t need the Pretty case it comes in and using it in my 9ft tent. Last grow I grew several 17 grams cola’s, and am looking for bigger one’s this grow. I wanted to put in a picture, but there is no where for attachments. Very satisfied with my purchase.

      I would really love to see the grow. I am actually in the market for some lights its getting way too hot in the tent and with summer just around the corner this looks to be the best thing out there. I’ve been asking a lot of questions also and was told that it works exceptionally well; I think they were talking about you. I am so glad that I seen your review, I am ordering 2 of the kits right NOW!!!

      The Hydroponic fixture was designed for plants highlighting the 410-460nm and emphasizing the 600-670nm to optimize photosynthesis. Of course plants use all available light and the RGB clusters offer a complete full spectrum. We’ve expermentet with many LED options for indoor plant growth and found that Cumbers gravitate their growth towards our optimized fixture..To be specific our grow area has the Cree CXA 2530 mixed with 3&5.5K and the Hydro fixture on the sides…The CXA 2530 does grow but the optimized XTC is prefered based on plant growth/orientation.
