    Hi all,

    Im currently looking at lighting options for a tank that is 48" Long by 24" wide and 18" Height. Ive been contemplating, kessils either two 360s or two 160s or two Radion XR15 FW G4 led fixtures.

    The only red plant im planning on having is Alternanthera reineckii. I understand Kessils are not known for their good growth of red plants, but are the radion XR15s sufficient?

    The only reason Im contemplating the kessils is for the shimmer as it makes a tank look more natural.

    Kessils will grow red plants just fine, the complaint is color rendition that many people have. It’s hard to really say which light is best, as it depends on what you consider to be pleasing to YOUR eye. All of the higher end lights will grow red plants, whether they look red enough to you is the question. Don’t rely on photos from the internet as they are mostly edited or corrected automatically by the camera. The heavier the red spectrum the more likely your reds will pop.

    Yeah, I really need to see the lights in the flesh. It’s just going to be difficult to view the Radions.

    I’m leaning towards the radions for more customisation and the fact they replied same day to a question, where as I’ve still not had a reply from Kessil (sent on Monday)

    From what I’ve seen, the radions will still generate glitter lines just not as well as Kessil.

    Every LED will give you some sort of ripple effect, the more surface agitation you have the better the effect. Kessil can actually be too distracting depending on the setup, almost so much that it looks "trippy"

    It seems quite hard to find information about peoples experiences of the radions, yet if I was buying reef lights, I would be able to find pages and pages of peoples experiences.

    Are the radions a good light?

    Kessil 160 is not quite enough on my 60x18 footprint tank. However it’s also 26” tall so that extra depth is important. The color is supposedly 6000-9000K which so there is a relative lack of red.

    While the shimmer can be distracting, there is no disco effect in the shadows and I can focus on things in the tank. I find that I have trouble focusing on things under Hydra 26s. They look like they’re lit by static or excessive flicker to me. I’m not sure if that’s disco effect related or simply due to them generally running much bluer light and my older eyes don’t focus as well with that light anymore.

    Given your tank size you’ll have probably need the Kessil 360 for coverage. I don’t have any experience with the Radions but the Hydras are fairly durable from what I’ve seen so that seems like a reasonable choice even if it’s not the same company. The new Kessil 360x should address the red appearance issue but then you’re up in the GHL Mitras price range when you figure in the controller.

    Out of curiosity who makes your tank? The dimensions seem like a good size.

    Radions do not have filter lines like Kessil’s I have both lights. Both lights are more geared to reef than planted tanks. If you get either one it would be best to use a PAR meter to set the light up with.
