LED Bulbs

LED Replacement Bulbs for Every Socket Type

We carry over 100 LED bulb options at KASTLITE, covering the most common base types and form factors. Whether you are swapping out a single porch light bulb or re-lamping an entire office building, you will find the right fit here. I stock A19, BR30, PAR38, corn cob, T8 tubes, PL, and candelabra base LEDs, all from brands I have tested and trust.

The biggest reason customers switch to LED bulbs is the energy reduction. A 9W LED replaces a 60W incandescent, and a 15W LED corn cob replaces a 100W metal halide. The math adds up fast when you are running dozens or hundreds of fixtures.

Choosing the Right LED Bulb

Start with three things: base type (E26, E39, GU24, etc.), wattage equivalent, and color temperature. If you are replacing fluorescent tubes, our light panels and tubes collection has LED tube options that drop right into existing fixtures. For outdoor post light applications, look at the higher-wattage corn cob LEDs in this collection paired with our globe covers.

We also carry a full line of Light Efficient Design LED retrofit bulbs for commercial HID conversions. These screw directly into existing mogul base sockets and include internal drivers, so no ballast bypass is needed.
