Great vintage X-Ray department radiation warning light box sign.
Originally used above the door of the X-Ray room in a hospital to warn against entering when X-rays were being carried out!
Now rewired and fitted with LED lighting so won’t get hot, makes a fab lamp or wall feature. Fitted with a plug and an in-line switch, however could be hardwired by a qualified electrician.
They all show wear from use and age, but are still good. 
Measurements: 23.5 x 8 x 16.5 cm high
