Applied Energistics Lights
Vibrant Quartz Glass
A variant of 
Quartz Glass
that glows like 
Glowstone.
Illuminated Panel
Can be used as a light source if powered by
ME Cable,
but this is mostly used as a crafting ingredient for the
ME Terminal.
Craft it by itself to get Light and Dark variants. The variants are just an aesthetic change and does not affect Light output at all.
