The Samsonite Black Label X'Lite is a great choice for your needs.
Samsonite Lite Pack and Go is very light weight and can take a beating.
I seem to recall that at one time Samsonite had a line of luggage called Ultra-lite (or Ultra-Light), but today many companies call their luggage "lite", or "light", or "ultra-lite", etc. But do not believe the claims. Weigh the luggage yourself and compare. Most rolling luggage will be about the same. If you want real light weight luggage look for a hard-side polycarbonate piece of luggage.
The sun provides both day and night light. Daylight directly from the sun and night light when it is reflected back from the moon.
Electricity provides the energy to light a light bulb. When the electricity flows through the filament in the bulb, it generates heat and light.
A light source such as a light bulb or LED provides illumination for viewing materials on a slide through a microscope. The light passes through the slide and the magnified image is then viewed through the eyepiece of the microscope.
