Seems to me that something sold as a "spotlight" should have some method of emitting photons, or it wouldn't be a "light".
Can't the seller suggest a bulb type and part number (and a place to purchase)?
I remember seeing some kind of bulb with a pigtail (may have been something other than halogen - probably HID), but can't find them now (not much help, sorry.)
If it were me, it would be on the way back to the seller as a deceptively advertised product. Handheld spotlights in retail shops aren't all that expensive.
