Internal Refractor Kits


Spring City offers two standard internal refractor kits.  These prismatic glass refractors are made from a special lighting grade borosilicate glass that provides a high resistance to heat and thermal shock and are optically designed to create the desired photometric distribution.

The smaller six inch diameter model is designed for use with lower wattage medium base lamps and available in an IES Type III or V Distribution.  While the larger eight inch diameter refractor can be used for applications requiring a mogul base or higher wattage lamps with a Type II, Type III or V distribution.
