Where does my creativity come in? The material and the LED lamps seem to be doing all the work!

That material and LED are the creativity... :p

This is great idea. might try out some time.

I hope the dome doesn't doom the life of the lamp by storing heat. It seems strange to me that the domes did not reflect more of the light pattern down, though it might have been blocked by your heatsink for the LED leads.

The pattern came out very prettily. I could wish for more variety in those reds, but it came out rather nicely.

Belaboring it with chained-source lightpipes, live plant and artificial lightpipe mixes, freshbulbs, etc. could bring out a bit of creativity (almost by default; creative habits are important.)

If you used phatlights, that would be a neat changeup too; though you would have to make a different model of how the giant-size version were assembled.
A nice realist source opportunity lamp would be neat; if you assert certain losses and outcome opportunities in the transmission line for example, are the losses in storage or usage improvements that much more optimal? In that kind of rendering, ideation is seemingly dark.
