Walk into an Orthodox home late at night, when every other light is off, and you will often see one small flame still burning. It sits in a glass cup of oil before the icons, quiet and steady, like someone keeping watch while the family sleeps.
That little flame is the kandili, the vigil lamp. In Georgian homes we call it the kandeli. It costs almost nothing to keep, and yet for many Orthodox Christians it is the heart of the prayer corner. Have you ever wondered why it matters so much, or why so many of our lamps keep going out?
Let me tell you a little about this light, and about the small cork float that keeps it burning.
From the earliest centuries, Christians have lit lamps where they pray. In the Old Testament, God commanded that a lamp be kept burning continually in the tabernacle. Today every Orthodox temple has lamps hanging before its icons.
At home we do the same thing on a smaller scale. The vigil lamp is not decoration. It is a small, living offering placed before Christ, the Mother of God and the saints.
Our Lord said, "I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life" (John 8:12). The flame before the icon reminds us of that promise every time we pass by. It also reminds us of what we are called to become: people who carry His light into a dark world.
A lamp burns quietly, without asking for attention, until its oil is gone. Saint Paul tells us to "pray without ceasing" (1 Thessalonians 5:17). Most of us cannot do that yet. But the lamp can keep a small vigil for us while we work, cook and sleep, and it calls us back to prayer when we see it.
Orthodox families have different customs, but here are some of the most common ways the vigil lamp is used at home:
Pure olive oil is the traditional fuel. Olive oil has a special place in the life of the Church: it is used in anointing, in the blessing of the five loaves, and in the Mystery of Holy Unction. Burning it before the icons makes the lamp a small echo of the Church's prayer.
When you light it, you might quietly say, "Let my prayer be set forth before Thee as incense" (Psalm 140:2). Or simply make the sign of the cross and remember God.
Here is the practical problem that almost every new Orthodox household runs into. You buy a beautiful glass vigil lamp, fill it with olive oil, and try to light a wick. It smokes, it drowns, or it goes out after ten minutes.
The answer is a tiny piece of equipment that has been used in Orthodox homes for generations: the floating wick holder, or kandili float.
It is simple. A small disc of natural cork rests on the surface of the oil. On top of it sits a thin metal plate that protects the cork from the heat, and a wire holder that keeps the wick upright and centred. As the oil burns down, the float sinks with it, so the flame always stays at the right height.
Many people pour a little water into the bottom of the glass first and then add a layer of oil on top. The oil floats on the water, and the float rides on the oil. This uses less oil and keeps the glass from overheating at the bottom.
A few tips from our own prayer corner:
Use a short cotton wick, just a few millimetres above the metal. A long wick smokes and blackens the glass. Trim the burnt tip before relighting. Wipe the glass every few days so the flame shines clearly. And never leave a lamp near curtains, paper icons or anything that can catch fire. Place it on a stable shelf or hang it securely, and always use common sense, especially with children and pets in the home.
The kandili float is one of the best-selling items in our store, and it is not hard to see why. It is the part of the vigil lamp that wears out. Cork softens with time, and metal bends after months of daily use, so families come back for new ones again and again.
We offer it in two sizes. The Small float fits most home vigil lamps and compact glass cups in a prayer corner. The Medium float suits larger oil lamps and church use. Each has a natural cork base, a heat-resistant metal top and wire wick holders, and works with olive oil and traditional lamp oils.
Many customers order several at once: one for the home lamp, one for the lamp at a grandparent's grave, and a few spare for the next months. They also make a thoughtful small gift for a newly illumined godchild or a family setting up their first prayer corner.
Often the humble things are the ones that keep our prayer going.
If your vigil lamp keeps going out, or you are setting up a prayer corner for the first time, order a kandili float here and keep a small light burning before your icons. Shipping is free on orders over $70, so it is a good moment to add incense, charcoal or a beeswax candle too. May the Lord bless your home.
Which oil should I use in my vigil lamp?
Pure olive oil is the traditional choice and burns cleanly with a good wick. Some people use special lamp oil. Avoid scented or mixed oils, which can smoke and stain the glass.
Is it safe to leave the lamp burning overnight?
Many Orthodox families do, but only in a stable glass, away from anything flammable, and out of reach of children and pets. If you are unsure, light it during prayer and extinguish it before you sleep. Our Lord sees the intention of the heart.
