this is not exaclty what we told you @ Interzoo. We have two lines of LED-Clusters (with computer optimized Refelctors) in order to get an uniform Light distribution at a wide area below the penpant. Hereby your aquarium will be illuminated more equally and you are more flexible to place stoney (SPS) Corals.

It is incredible important to have the same high par readings in a wide area. Not the typical highest par readings in the center below the pendant an not enough light in the outer areas.

That is the reason why we use two lines of LED-Clusters in our Sirius. Also, the distance of each LED is exactly calculated. The Sirius is designed to have an even Par-distribution. Dont forget, we are manufacture of T5-lights for a long time and we have an own lab to control and to work out everything.

If we would add another line of LED-Cluster in the center, we simply have too much light in the center. More than that. It would lead to an uneven light distribution (to much light in the center) and a higher risk to burn corals.

Also, it is not just the Sunpower body. I agree it looks similar. But this is caused by using the same material for the housing. Inside the Sirius we use massive Alumium-profiles. We decided to use the same housing-material for different reasons:
1. It is proven, lightweight, durable and rust-proof.
2. It is made of aluminium. In this way the complete housing can work as a heatsink, too

By the way, you can control the temperature of all LED-Cluster every time at the Display.

Ok, I just want to jump in here, before something leads to misunderstandings.

Thanks and best regards,

Thanks for jumping in! So would the X2 be a good fit for a 24x24x20 cube? Also, can the LED clusters be changed out in the future if a LED burns out?
