Testing was done by booting from a Live USB on a 1 GB RAM computer. Idle RAM Usage was determined using the 'free -m' terminal command. Quelitu Jazz usage is adjusted for accuracy. Once installed, RAM Usage is somewhat lower.

For a lower RAM usage, Quelitu offers a lot more than other Linux operating systems.
See Release Notes/Download and Videos & Tutorials for details.
Enlightenment E17 is lighter than Lxde.
