this is exactly what I needed! The 24" might just work for me - was looking at the Ray2 but it is way too much of a flamethrower for a low tech tank

PS: Make the ray2 dimmable and you will have a great response - I would have ordered it days ago!

Okay i'm having a little trouble understanding this chart.
I need a 30" fixture for my 20 gallon long tank which is 12" in height.
from the chart I guess it would be 48 PAR but what are the dots next it with the 47/36/27 numbers for?

That's showing you how much the light falls off when not under the center of the light (across the bottom - 0 = directly under the light, 3 is 3" to the side, 6" to the side, etc.)

okay so 0 means having the fixture set in the middle of the tank instead of say in the front part of the tank?

0 is directly under the light, so if the light is at the front edge of the tank, the PAR listed will be straight down along that edge, gradually getting weaker towards the back. Wouldn't recommend that though, sounds like that would be asking for algae on the glass.

If the light is towards the middle, than the area directly under the light would be the strongest number, and towards the front and the back would get gradually dimmer.

That 30" is just about perfect for a 20L.

Never argue with a fool. Onlookers often can't tell the difference.

Yes it is.

This data just pushed me from 'leaning towards picking up a few' to 'definitely picking up a few.'

Hi,

Are those PAR readings taken through water or air? Also, what is the estimated average temperature rating of the LED's? I see a lot of 'blue' ones (approximately 33%) so I am guessing above 6700K.

I got myself a 30" for my 20L and so far so good. Great Light distribution across the entire tank. I am liking this new 30" model.

I just got it today and despite subpar packaging I love the fixture, I can't decide if I like it better with or without the blue lights.

Is there gonna be a 36" FugeRays? and is there any PAR ratings for the RayII 36"?
