How fun would this be? This Temperature Controlled Faucet Light changes with the relative heat/coolness of the water. A great way to keep your young children from getting burned, a wonderful sci-fi light show, best of all, it’s simple to install!
Red lights illuminate the water stream when hot, and blue shines through the stream when cold. The red light is turned on for temperatures of 89 degrees and above.
Works on most USA faucets and includes universal adaptors for 95% coverage. Simply unscrew old aerator and screw on the Faucet Light.

Will see what I can find out.
You’ll have to contact the company directly for that information Greg.
What are the gallon per minute flow rates on the faucet aerators Do they come in low flow models?
