F7 Fluorite crystals from England fluorescent rocks Filtered Shortwave fluorescent tube: 11

Filtered Shortwave fluorescent tube: 11 Watts - Short wave bulb is included behind filter glass covering

Under shortwave UV responds a ghostly blue with a fantastic afterglow once the UV light is turned off that lasts for seconds

Whitish yellow response under longwave

Note: ninety percent of all fluorescent rocks need a filtered shortwave UV light source 254nm (NOT A BLACKLIGHT) The M101HO includes both longwave and shortwave UV light

Canada strongest response under yellow longwave UV

F7 Fluorite crystals from England fluorescent rocks Filtered Shortwave fluorescent tube: 11F7 5x4x2 3 pounds 1. 6 oz from Rogerly England super rich fluorite with amazing crystals. You could use CLR to remove the rust and get deeper green daylight crystals. The whole specimen responds under shortwave or longwave UV even with just sun exposure! Fluorite from this location is very difficult to photograph due to the brightness of the deep purple response.
