Antique Oil Lamps & Electrified Conversions: What to Know

If you’ve ever picked up an old oil lamp and wondered, “Is this really antique… or just made to look old?” — you’re not alone.

Antique oil lamps are one of those categories that look simple at first glance, but there’s actually a lot going on. And once you understand the parts, it becomes much easier to tell what you’re looking at.

Let’s start with the basics.

A true antique oil lamp from the late 1800s or early 1900s was originally designed to burn kerosene. You’ll typically see a metal burner assembly (sometimes stamped with names like Rayo or other early manufacturers), a glass font that held the fuel, and a chimney or hurricane shade.

Now here’s where things get interesting: when electricity became common in American homes in the early 20th century, many families had their oil lamps converted to electric. Instead of throwing them away, they adapted them. That’s why you’ll often see antique oil lamp bases that have been professionally electrified.

And that’s not a bad thing.

In fact, early electrified oil lamps — especially those converted in the 1920s–1940s — are part of lighting history. The key is whether the original components are still intact. If the base is authentic and the burner is original, you’re looking at a genuine antique that evolved with the times.

So how do you tell what you have?

Look for:

• A stamped burner (names like Rayo are common and desirable)
• A substantial metal or brass base with age-appropriate wear
• Milk glass or etched hurricane shades
• Wiring that looks period-correct rather than brand new

Many antique oil lamps were made by American manufacturers like Miller, and finding a maker’s stamp is always a good sign. The weight, patina, and construction quality usually tell you more than shine ever will.

One important thing: over-polishing can actually reduce character. Honest wear, subtle patina, and even minor imperfections often confirm age. A piece that looks too perfect may be a later reproduction.

Electrified oil lamps are popular today because they combine antique charm with modern function. They work beautifully in traditional, colonial revival, cottage, and even eclectic interiors. And unlike purely decorative reproductions, these pieces have a real story.

So if you’re considering an antique oil lamp, don’t be afraid of a conversion. Just make sure the original bones are there.

Once you know what to look for, you’ll start spotting the difference immediately.
