Keystone’s Essential Series LED Spotlight Bulbs are ideal for replacing small halogen bulbs, as well as in new construction applications. Halogen spotlights emit a substantial amount of heat and require shielding from possible shattering in open fixtures. Our LED spotlights offer lower heat generation than legacy equivalents and are rated for open and recessed fixtures without any additional protection needed.
The Essential Series PAR16 and MR16 GU10 LED spotlights operate off of 120V input power and do not require a transformer. For the MR16 12V LED spotlights that do require a transformer, Keystone offers compatible low voltage transformers. For a full list of compatible transformers, go to our compatibility list page.
