The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
Edward Lytener is a master inventor, specializing in miniature electronics and manipulating light. Prior to becoming Luminus, Edward developed devices such as laser guns, remote-controls capable of overriding an automobile's functions, and a suit of powered armor that emitted red sun radiation which granted him enough strength to go toe-to-toe with Superman (for a while, at least).
As Luminus, Lytener is armed with a laser pistol and a device capable of projecting duplicates of himself or making himself invisible. With proper preparation, he can create any variety of holographic projections, and is even capable of making light solid (which was once explained that he's able to do so with just the right kind of laser field).
As of the Justice League episode "Only a Dream," Luminus is now able to project hard light duplicates of himself at will.
