Looks pretty fair.
How's this?
Lightburst (Su): Once per day, a telperan can release a burst of blazing light in a 5-foot radius. All creatures in the area are blinded for one round (Reflex DC 14 negates). Additionally, any undead creatures caught within the area take 2d6 points of damage, or half damage if a DC 14 Reflex save is successful. An undead creature to which sunlight is harmful or unnatural takes double damage. The ultraviolet light generated by the spell deals damage to fungi, mold, oozes, and slimes just as if they were undead creatures. The save DC is Charisma-based.
I basically just toned down sunburst greatly.
