Will 30% Hydrogen Peroxide light in fire with a match?

Will 30% Hydrogen Peroxide light in fire with a match?

As far as I know it will not.

But more concentrated (>90%) may decompose with an explosion.

No, when you put a burning match in the liquid, the match will stop burning and nothing further happens. There simply is too much water, even in 30% H2O2.

What is the concentration of Hydrogen Peroxide in glow sticks?

The light stick contains two chemicals and a suitable fluorescent dye (sensitizer, or fluorophor). The chemicals in the plastic tube are a mixture of the dye and a derivate of phenyl oxalate ester (also called Cyalume). The chemical inside the glass vial is concentrated (about 35%) hydrogen peroxide.
