We may start doing bigger refugium lights. We did this with the lumenbars for a while, and unfortunately they weren't very well received. I think the next step up would be something in the 30watt range. The 7watt ones we have now do very well. If we were to do a 24" one, it would only replace about 3-4 of the pico fuge LEDs we carry now, so the cost would have to be similar to justify that.
