Sunbrite actually made Modular LED lights (with a different twist on it) and they were pretty good. Just extremely expensive. They were structured similar to T5 lights in the sense that they were screw in LED bulbs into light housing with a controller. Not sure how these slimlines will work out but it is a very attractive light.
The good selling point is that it mounts on the back of the tank and looks like it covers a nano pretty well.
I saw the sunbrite but at 209.99 for the fixture then 149.99 for the bulbs which aren't included you are looking at 1409.91 before tax and shipping for the fixture if you want to fill all 8 spots with the LED tubes.
209.99+ (149.99 x 8) = 1409.91 Plus tax and shipping.
