Sold/Expired LED drop in for Streamlight UltraStinger?

[Novanet]

Does anyone make such a component? I have an older incandesant Streamlight UltraStinger which I would like to purchase or learn how to mod into an LED light. Pretty much a noob here, but learning alot so far. I searched for thread info on this particular question but could find nothing...

Any ideas?

Any update to this one? I have the TerraLUX LED upgrade for the stinger, but don't see one for the UltraStinger yet.
