Unlike its predecessors which were primarily constructed from sheet metal the Pattern 23’s body was manufactured from aluminium, using high pressure die-casting.
Strands ‘Baby Spot’ the Pattern 23, and its companion the Pattern 123 fresnel, revolutionised stage lighting, using optics and reflector technology which provided over twice the light output of any similar wattage spot of the day. [ The Pattern 23 was the ETC Source Four of its day ]
