How to Replace G8 Bulbs in Pendant Lights and Sconces

Quick answer

To replace a G8 bulb, turn off power at the breaker, let the old bulb cool, then pull it straight out of its socket. Align the two pins of the new G8 bulb with the socket holes, press it in firmly and evenly without twisting, and restore power. If the fixture uses a G8 DTW LED bulb like the one in our Pearl 6 fixtures, no warm-up is needed.

G8 bulbs are compact bi-pin lamps common in small pendants and sconces where a standard screw-in bulb won't fit. Because they push straight into a ceramic or plastic socket instead of screwing in, the replacement process is quick once you know the two or three details that cause most problems. This guide walks through the full job, from cutting power to testing the new bulb.

You don't need special tools for most G8 swaps, but you do need to be careful with the pins. Bending them is the most common mistake, and it can make a new bulb feel like it doesn't fit when the real issue is alignment. Work slowly, keep the fixture steady, and check the socket before you push anything in.

What you need before you start

Gather a replacement G8 bulb, a soft cloth or clean gloves, and a small step stool if the fixture is overhead. Check the old bulb's markings or your fixture manual for the correct wattage and color temperature. If you're unsure, match the existing bulb's specs rather than guessing; a bulb with the wrong pin spacing won't seat properly.

G8 refers to the pin spacing, not the shape or brightness. A G8 DTW LED Bulb - 7 Watts, for example, uses a bi-pin base and is rated for 2700K-1800K dim-to-warm color, 550 lumens, and a 25,000-hour lifespan. That kind of detail matters because a physically similar bulb with different electronics may not dim the way your fixture expects.

• Confirm the socket type is G8 (8mm pin spacing) before buying a replacement.
• Keep the old bulb until the new one works, in case you need to compare pin spacing.
• If the fixture is on a dimmer, check that the replacement bulb is dimmer-compatible.

Step 1: Cut power and let the fixture cool

Turn off the wall switch, then switch off the circuit breaker that controls the fixture. Test with a non-contact voltage tester or try the switch once more to confirm the light stays off. Even LED bulbs can be warm after use, and metal sockets hold heat, so give the fixture a few minutes to cool before touching anything.

This step is non-negotiable for ceiling pendants and wall sconces. If the fixture is outdoors or in a damp location, treat the breaker as the only reliable off switch, since a wall switch may be wired differently than expected.

• Common mistake: trusting only the wall switch when the circuit may be shared.
• Checkpoint: the bulb should be cool enough to touch comfortably before you proceed.

Step 2: Remove the old G8 bulb

Grip the bulb gently and pull it straight out of the socket. Don't twist; G8 pins are designed to slide, and twisting can crack the ceramic socket or shear the pins. If the bulb won't budge, check for a retaining ring or clip that holds it in place, then release that before pulling.

If the old bulb is broken, use a cloth to protect your fingers and remove any glass fragments before inserting the new bulb. Never force a bulb that seems stuck; a stuck bulb usually means the pins are corroded or slightly bent, and forcing it can damage the socket.

• Common mistake: twisting the bulb instead of pulling straight out.
• Checkpoint: inspect the socket for debris, corrosion, or bent contacts before moving on.

Step 3: Align and insert the new G8 bulb

Line up the two pins with the two holes in the socket. The pins are small and easy to misalign, so look at the socket from directly in front rather than at an angle. Once aligned, press the bulb in with steady, even pressure until it seats fully. You should feel it stop, not crunch.

If the bulb doesn't go in easily, pull it out and check the pins. A pin bent even slightly will prevent full insertion, and pushing harder can snap it. Straighten a minor bend carefully with small pliers, or use a fresh bulb if the pin is badly deformed.

• Common mistake: pushing at an angle and bending a pin against the socket edge.
• Checkpoint: the bulb should sit flush and feel secure with no wobble.

Step 4: Restore power and test

Turn the breaker back on and flip the wall switch. The bulb should light immediately; LED G8 bulbs don't need warm-up. If it flickers, turn the power off again and reseat the bulb, since a loose pin contact is the most common cause of flicker in bi-pin sockets.

If the bulb still doesn't light, try it in a different G8 socket to rule out a bulb defect. If it works elsewhere, the original socket may have a loose contact or a wiring issue that needs an electrician.

• Common mistake: assuming a flicker means a bad bulb when the socket contact is the real issue.
• Checkpoint: test the fixture at full brightness and, if applicable, at low dimmer settings.

Step 5: Handle the old bulb and dispose of it properly

Let the old bulb cool completely, then wrap it in paper or its original packaging before disposing of it. LED bulbs like the G8 DTW LED Bulb - 7 Watts contain electronic components, so check local rules for electronics or lamp recycling rather than tossing them in general trash where prohibited.

If the old bulb still works, keep it as a spare. G8 bulbs are small and easy to lose, and having a known-good spare makes future troubleshooting faster.

• Common mistake: throwing a still-warm bulb into a bin with flammable material.
• Checkpoint: label the spare with its color temperature and wattage so you can match it later.

G8 replacement steps at a glance

1. Cut power and cool: Switch off the breaker and let the fixture cool before touching the bulb. Checkpoint: confirm the light stays off with the switch.
2. Pull the old bulb straight out: Grip and pull; never twist a G8 bulb in its socket. Checkpoint: inspect socket contacts for damage or debris.
3. Align and press in the new bulb: Match the two pins to the two holes and push evenly until seated. Checkpoint: the bulb should be flush with no wobble.
4. Restore power and test: Turn the breaker on and check for steady light and correct dimming. If it flickers, reseat the bulb before assuming it's defective.
5. Dispose of or store the old bulb: Cool, wrap, and recycle the old LED bulb, or keep it as a labeled spare. Checkpoint: note the wattage and color temperature for future swaps.

G8 bulb facts that affect replacement

• G8 DTW LED Bulb - 7 Watts: G8 DTW LED Bi-Pin Base Bulb, 2700K-1800K, 550 Lumens, 7 Watts, 90+CRI, bulb lifespan 25K hours. Included in our Pearl 6 fixtures. If your fixture is part of the Pearl 6 family, this is the exact replacement bulb. Its dim-to-warm range means it shifts from 2700K to 1800K as you dim, so a standard fixed-color G8 bulb won't reproduce that behavior.
• A19 DTW LED Bulb: A19 DTW LED Medium Base Bulb, 2700K-1800K, 480 Lumens, 6 Watts, 90+CRI, bulb lifespan 15,000 hours. JA8 compliant. Included in our Hood family of fixtures. This is not a G8 bulb, but it's the correct replacement for Hood family fixtures. Knowing the difference prevents buying an A19 for a G8 socket, which won't fit at all.
• G16.5 LED Bulb: G16.5 Frosted LED Candelabra Base Bulb, 2700K, 450 Lumens, 5 Watts, bulb lifespan 15,000 hours. JA8 compliant. Included in our Grain Drum 14 fixtures. Another non-G8 example: the G16.5 uses a candelabra base. If you're replacing a bulb in a Grain Drum 14, this is the right part, and its frosted finish softens glare in open fixtures.

Replacing a G8 bulb comes down to three things: killing power, pulling straight instead of twisting, and aligning the pins before you push. Do those and the job takes a few minutes. If a new bulb still won't light after reseating, test it in another G8 socket to tell a bad bulb apart from a socket problem.
