Horizontal LED Corn Light E39 | 80W to 48W Selectable, Tunable CCT

A retrofit lamp that lies on its side

Standard corn lamps point straight down out of the socket. That works in a high bay hanging from a ceiling. It does not work in a wall pack or a shoebox, where the socket faces sideways and the lamp ends up throwing most of its light at the inside of the housing.

A horizontal lamp puts the emitters along its length instead of around a vertical tube. Fitted into a sideways socket, the light goes out of the fixture rather than into it.

Specification

Vertical or horizontal

If you are not sure, open one fixture and look. Ordering the wrong orientation for a site of fifty fixtures is an expensive way to find out.

Selectable wattage on a retrofit

Useful because you rarely know the right output until the first one is in. Fit one, stand underneath at night, and set the rest to match. Trying to calculate it from the old lamp's wattage rarely lands right, since the old fixture's reflector and lens have usually lost efficiency over the years.

Ballast bypass

As with any corn lamp, the existing ballast normally has to be removed and the lamp wired direct. A ballast built for metal halide will damage an LED lamp. This is mains wiring and belongs with a licensed electrician.
