This is a hero, light up, UV bomb as seen in Guillermo del Toro's film, Blade II, starring Wesley Snipes.

This prop is made from various materials and features a rechargeable inner battery and a plug that once removed, lights up all the blue leds in all the facets of the bomb.

You can clearly see this specific type of prop in the workbench when Whistler (Kris Kristofferson) tests one of them (FX added CGI to the bomb to make the deadly UV beams appear).
