The manual lists the model as Tetra LED24-W but doesn't specifically state they're 1w each.I dont' see any specs but I don't see any specs that says they're 24x 1W?
They don't look like high powered LEDs.
Lumens/watt would be bulb-dependent, wouldn't it?I would calculate a lumens per watt and then consider if there's a metal, polished, or painted parabolic fixture of some sort.
It's done well enough with mosses and java fern and okay with m.mattogrossense and lysimachia if the stems are 5" or more to start with. Two fast-growing species of hygro won't do well in that tank and I think I've ruled out deficiencies other than light.Answer is no.
I don't know much about lighting, but the lamp you showed won't even do. I've seen that at a LFS and it didn't look like it was able to grow anything.
