I already had the lamp, and the bulb is not replaceable. If I had the option, 6500K would be preferred for plant growth.
What alternatives were you referring to in your question? Snail? Lighting?
Just spit balling. I can't get a hold of dwarf sag, so do you tihnk I'd do well with pygmy chain sword? And do LED bulbs with blue and white colour spectrums exist with a base of GU10/any base used with desktop lamps?

If you have enough growth in the vase and it doesn't get too hot, you might be able to get away with an amano shrimp or a couple cherry shrimp in there to munch on algae. It's going to poop as well though, honestly. It's small, so water quality changes will be fast and unforgiving. You'd really want to get the plants going well before adding anything whose survival you care about.
Not sure about obtaining shrimp in Australia, but I'll look into what's available.
If the plants in my test jar are currently pearling (rotala sp. green and hygrophila polysperma), could this suggest that my lighting will be sufficient to grow pgymgy chain sword and other low-medium light plants?
I know that I'll be putting in the ADA AS with nothing else and then doing big water changes daily to get rid of the amonia spike, but what about after the first week when I add plants and everything begins settling? I assume I'll have to do a test on my tap water and see just what I'm putting in there, as well.
Edit: It seems that I can easily get a hold of some ghost shrimp (Paratya australiensis). Would these be suitable? They look pretty cool!
