LXLE is based on Lubuntu which is an Ubuntu OS using the LXDE desktop environment. It is designed to be a drop-in and go OS, primarily for aging computers. Its intention is to be able to install it on any computer and be relatively done after install. At times removing unwanted programs or features is easier than configuring for a day. This distro follows the same LTS schedule as Ubuntu. In short, LXLE is an eclectic respin of Lubuntu with its own user support.
Minimal and lightweight seem to become intertwined when speaking of an operating system for aging computers, aka lightweight systems. Lightweight simply refers to the amount of system resources needed for the system to operate. A minimal system is much more about ISO file size as it tends to have very few programs installed by default, which in turn makes it minimal. It’s often true that many lightweight operating systems are also minimal. LXLE does not strive to be a minimal OS, yet lightweight is something the distribution tries very hard to ensure.
