This detailed fantasy model is printed in grey and clear resin and lit by an included LED. No soldering or wiring needed. LED lights are self contained with batteries and a removable (and replaceable) tag. I generally get 70 hours or more from these lights when on continuously. They can be turned back off by reinserting the tag and replaced inexpensively when dead or swapped for additional colors for effects (we sell extras in a separate listing). They are sized to work with 28mm/32mm miniatures on a 1"/25mm gaming grid.
