As far as I see it, sunrods are an alchemical item. They glow about as bright as a torch. Now normally I'd rule they would burn rather hot, but as I can't find any rule to support that, I'll allow them to be used as you guys intended.<br/><br/>Magical fire tends to ignore the caster's clothing, as it is pointed outward from them, but it does affect the clothing of anyone it hits.
