E26 is the standard medium screw found in domestic and light commercial fixtures. E39 is the larger mogul base used on industrial gear. Look at the socket before ordering — an E39 lamp will not go into an E26 holder, and an adapter adds a failure point at the one connection carrying all the current.\u003c\/p\u003e\n\n\u003ch3\u003eBypass the ballast\u003c\/h3\u003e\n\u003cp\u003eThe existing ballast normally has to come out, with the lamp wired direct to the supply. A ballast built for metal halide will damage an LED lamp. This is mains wiring and belongs with a licensed electrician.\u003c\/p\u003e\n\n\u003ch3\u003eMeasure the housing\u003c\/h3\u003e\n\u003cp\u003eA corn lamp is longer and wider than the lamp it replaces.
