Learn how to pick the right bulb for your table lamp, including wattage, size, and color temperature, with practical decision rules and trade-offs.
Quick Answer
For most table lamps, choose an LED bulb with a wattage within the lamp's maximum rating, a base size that fits the socket, and a color temperature that matches the room's mood. Start with 60W equivalent, E26 base, and 2700K for a warm, inviting glow.
Wattage: Match the Lamp's Rating
The wattage rating printed on your lamp is the maximum safe wattage for the socket. Using a bulb with a higher wattage can cause overheating and damage the lamp or fixture. For LED bulbs, the wattage is much lower than the incandescent equivalent, so you can often use a higher equivalent wattage as long as the actual wattage stays within the limit.
For example, a lamp rated for 60W can safely use an LED bulb that draws only 9W but provides the same light as a 60W incandescent. Always check the lamp's label or manual for the maximum wattage.
Bulb Size: Fit the Socket and Shade
Bulb size matters both for the socket and the shade. The base must match the socket type, typically E26 for standard table lamps. The bulb's overall shape and length should also fit inside the shade without protruding or touching the shade material, which could be a fire hazard.
Common bulb shapes include A19 (standard), globe, and candelabra. For lamps with smaller shades or decorative designs, a globe or shorter bulb may be more appropriate.
Color Temperature: Set the Mood
Color temperature, measured in Kelvin (K), affects the ambiance of your space. Lower Kelvin numbers (2700K-3000K) produce warm, cozy light, ideal for living rooms and bedrooms. Higher Kelvin numbers (3500K-5000K) create cooler, more energizing light, better for task areas like desks or reading nooks.
For a table lamp used for relaxation, a warm 2700K is usually the best choice. For a desk lamp, you might prefer a cooler 4000K to boost focus.
Decision Rules for Choosing a Bulb
- Check the socket type: Look for the socket marking (e.g., E26) or measure the base diameter. Most table lamps use E26, but some mini lamps use E12 candelabra. Match the bulb base exactly. If unsure, bring the lamp or an old bulb to the store.
- Respect the wattage limit: Find the maximum wattage stamped on the lamp or socket. Choose an LED bulb whose actual wattage is below that number, even if the equivalent wattage is higher. Using a higher-wattage bulb can void warranties or cause fire risk.
- Pick the right shape and size: Measure the shade's interior height and diameter. Choose a bulb that fits inside without touching the shade. For shades under 10 inches tall, a globe or short A19 bulb works well. A bulb that sticks out can create glare or heat buildup.
- Choose color temperature by use: For reading or tasks, select 2700K-3000K for warm light or 4000K for cool white. For ambiance, stick to 2700K. Avoid mixing temperatures in the same room. Test a bulb in the lamp before buying multiples.
- Consider dimming needs: If your lamp is on a dimmer switch, choose an LED bulb labeled 'dimmable.' Non-dimmable LEDs will flicker or buzz when dimmed. Check the bulb package for the dimmable symbol.
Lamp Compatibility Notes
- Alexander Table Lamp: The Alexander Table Lamp has two E26 sockets and is rated for bulbs up to 60W (bulb not included). You can use standard E26 LED bulbs up to 60W equivalent, making it easy to find compatible options for this lamp.
Alexander Table Lamp - Vertebrale Table Lamp: The Vertebrale Table Lamp also uses an E26 screw base and recommends a bulb of 60W or less (bulb not included). This lamp gives you the same flexibility with LED bulbs, and its globe shade may suit a shorter bulb for a neat fit.
