Integrated LED vs. replaceable bulb: integrated LED is the go-to for very slim fixtures, hard-to-reach areas, or lights that stay on for long periods daily, while the bulb retains the advantage of freedom (color temperature, wattage, style) and easy, one-step repair. At the same light output, both consume the same amount of energy: the difference lies in lifespan, design, light quality, and adaptability. Here is an honest, point-by-point comparison and our room-by-room verdict.
The match-up in 5 points.
- 1Lifespan: 25,000 to 50,000 hours for an integrated LED (≈ 20 years at 3 hours/day); 15,000 to 25,000 hours per LED bulb, which can then be replaced.
- 2Consumption: identical for the same light output, since both use LED technology. Compare in lumens, not watts.
- 3Design: integrated LED allows for very slim fixtures (5 to 8 cm), precious under low ceilings.
- 4Freedom: the bulb lets you choose the color temperature (2700 K, 3000 K), brightness, and style, including filaments.
- 5Repairability: a bulb is changed in one simple step; for an integrated LED, check if the driver can be replaced.
— 01Integrated LED vs. bulb: what is the difference?
In both cases, the light comes from LEDs. What changes is how it is installed in the fixture.
- Integrated LED is permanently fixed: a module (a plate or strip of small LEDs) is powered by a driver, the electronic power supply that converts mains electricity. The whole assembly is custom-designed for the fixture along with its diffuser. There is no bulb to buy or change.
- Replaceable bulb screws or clicks into a socket. The fixture is merely a support: you choose the light source and can change it whenever you wish.
The direct result: an integrated LED fixture can be much thinner, but its light source is inseparable from the fixture. A bulb fixture is bulkier, but it evolves with you.
— 02Integrated LED vs. replaceable bulb: a point-by-point comparison
Here are the eight criteria that truly matter, without bias. Neither solution wins in every category: it all depends on what you expect from your fixture.
| Criterion | Integrated LED | Replaceable bulb |
|---|---|---|
| Lifespan | 25,000 to 50,000 h (≈ 20 years at 3 h/day) | 15,000 to 25,000 h per LED bulb, renewable |
| Slimness, design | Very slim fixtures possible (5 to 8 cm) | Fixture sometimes bulkier (socket + bulb) |
| Light quality | Often better distributed: module and diffuser designed together | Depends on the bulb chosen and its placement |
| Flexibility | Color and power fixed at purchase, except for adjustable models | Total freedom: color, power, shape, filament |
| Repairability | Depends on the model: driver or module sometimes replaceable | Simple: just change the bulb |
| Dimming | Brightness adjustment integrated on some models | "Dimmable" bulb + compatible dimmer switch |
| Consumption | Identical for same light output | Identical for same light output |
| Long-term cost | Source included: nothing to buy for years | Bulbs to buy and replace, with a new choice every time |
— 03Lifespan and repairability: what to really look at
On paper, integrated LED wins: 25,000 to 50,000 hours, or about 20 years at 3 hours per day, versus 15,000 to 25,000 hours for an LED bulb. But the comparison is not entirely fair: the bulb is replaceable. A fixture with a socket can therefore last much longer than its successive bulbs.
The real question is what happens if it breaks. With a bulb, repairs take a few seconds and require no tools. With an integrated LED, it depends on the design:
- ✓Replaceable driver: this is the electronic component to check first. If it is accessible and standard, an electrician can replace it without touching the rest.
- ✓Replaceable LED module: some fixtures allow you to change the LED plate itself.
- ✕Neither: at the end of its life, the entire fixture must be replaced. Inquire about this and the manufacturer's support before purchasing.
For a hard-to-reach fixture, hung very high in a double-height room or a stairwell, the longevity of an integrated LED is highly valuable: it reduces the need for maintenance at height.
— 04Slimness, design, and light quality
This is the great strength of integrated LED: without a socket or bulb, the fixture can be only a few centimeters thick. Ultra-flat LED ceiling lights demonstrate this well, such as the Orbélis (5 cm) or the Octélis (6 cm), and even the crystal chandelier Orvella, which uses integrated LED, is no thicker than 7.6 cm. Under a low ceiling, those few saved centimeters change everything: see our guide on which fixture for a low ceiling.
As for light, the LED module and the diffuser are designed together: the light is often better distributed, without hot spots or dark zones. This is particularly noticeable on ultra-slim ceiling lights and halo wall lamps.
A bulb, however, becomes a design element in its own right when exposed. A beautiful filament bulb in an industrial wall lamp or an open-work pendant provides charm that no integrated module can imitate. The flip side: an poorly chosen exposed bulb, if too powerful or too bright, can cause glare.
— 05Flexibility, color temperature, and dimming
With a bulb, you remain in control of your light. Want to switch from a 3000 K white to a warmer 2700 K white in the living room? Just change the bulb. Need more light over the table? Choose a bulb with higher lumens. To choose the right color temperature, see our comparison of 2700K vs 3000K for a living room, and for the amount of light, our method for how many lumens for a living room.
With an integrated LED, these settings are fixed at the design stage. This is why many LED fixtures incorporate a bit of flexibility themselves:
- Dimmable intensity: the Simplélis ceiling light, the Sylvélis, or the Rosélis can be dimmed.
- Choice of color temperatures: the Simplélis is available in warm, neutral, or cool white; the Noctaro floor lamp offers 3 light colors.
- Remote control: the Orvella and Velaria chandeliers, which feature integrated LED, can be controlled from a distance.
In any case, if you are using a wall dimmer, check the "dimmable" compatibility of the bulb or the integrated LED. Also, try to keep the same color temperature within a single room, with a maximum variance of 300 K between sources.
— 06E27, E14, G9, GU10: understanding light bases
If you opt for a bulb fixture, the base is the first piece of information to check: it determines which bulbs are compatible. Four formats cover the vast majority of household fixtures.
- E27: the large screw base, the most common. Pendants, floor lamps, table lamps: this is the one that offers the widest choice of bulbs, including filaments. The Globéil wall lamp or the Travébloc stone ceiling light use this base.
- E14: the small screw base for flame bulbs, small lamps, and many chandeliers with arms.
- G9: a small capsule with two loop pins that plugs in without screwing. It is found in wall lamps and compact fixtures where space is limited.
- GU10: the spot base, with two notched pins that lock with a quarter-turn. Convenient for changing the angle or the color temperature of a beam.
Filament bulbs: the decorative touch
LED filament bulbs replicate the look of vintage bulbs: visible glowing threads, clear/amber/smoked glass, and globe, pear, flame, or tube shapes. They are designed for fixtures where the bulb is visible, such as the Noctéil wall lamp with its exposed E27 globe bulb. Three rules: opt for amber glass or low wattage if the bulb is at eye level, stick to 2700 K for ambiance, and choose a dimmable version if the fixture is on a dimmer switch.
— 07Integrated LED vs. bulb: our verdict by room and use
- ✓Your ceiling is low and every centimeter counts
- ✓The fixture will be hard to access (high ceilings, stairwells)
- ✓You want diffuse, even light without a visible source
- ✓You are looking for a very slim wall lamp for a narrow hallway
- ✓You want to adjust color or power over time
- ✓The bulb is visible and part of the decor (filament)
- ✓The fixture is a table or floor lamp, easy to reach
- ✓You prioritize simple repair and adaptability
Room by room, here are our recommendations:
- Living room and bedroom: both work. Bulbs are great for table lamps and ambient pendants at 2700 K; integrated LED is perfect for a slim, dimmable ceiling light.
- Low ceiling: advantage integrated LED, for its slimness (5 to 8 cm).
- Entryway and hallway: advantage integrated LED for low-profile wall lamps; bulbs are possible for decorative wall lamps. See details in our guide on which lighting for a hallway.
- High ceilings: advantage integrated LED, to reduce the frequency of maintenance at height.
- Table and floor lamps: advantage bulb, as it is easy to reach and modular.

— 08The checklist before buying
- ✓I identify whether the source is integrated or bulb-based, and if so, what base (E27, E14, G9, GU10).
- ✓Integrated LED: I check the stated lifespan, color temperature, and whether the driver can be replaced.
- ✓Bulb: I think in lumens, not watts, and I choose 2700 K or 3000 K depending on the room.
- ✓I aim for a CRI of 90 or higher for faithful colors and skin tones.
- ✓Do I have a dimmer? I check for the "dimmable" label.
- ✓I maintain the same temperature in the room, with a maximum 300 K difference.
— 09Frequently asked questions
Integrated LED or bulb: what to choose?+
Choose integrated LED for a very slim light fixture, one that is difficult to access, or one where you want homogeneous light without a visible source. Prefer a replaceable bulb to maintain the freedom to change the color, intensity, or style, and for simple repair. At equal flux, both consume the same amount.
What is the lifespan of an integrated LED?+
An integrated LED is rated for 25,000 to 50,000 hours, or about 20 years at 3 hours of use per day. An LED bulb offers 15,000 to 25,000 hours, but it is replaceable.
What to do when an integrated LED stops working?+
Depending on the design of the fixture, an electrician can replace the driver (the electronic power supply) or the LED module. If neither is replaceable, the fixture must be changed: this is a point to check before purchasing.
Does an integrated LED consume less than an LED bulb?+
No: at equal luminous flux, they consume the same amount, since it is LED in both cases, with an efficiency of about 80 to 120 lumens per watt. Therefore, compare the stated lumens rather than the watts.
What is the difference between an E27 and E14 base?+
These are two screw bases: E27 is the standard large base, E14 the small one, used for candle bulbs, small lamps, and many chandeliers. The number indicates the diameter of the base in millimeters; check it on your fixture before buying a bulb.
Can you put a filament bulb in any fixture?+
Yes, if the base matches and the power remains within the limit indicated on the fixture. It makes the most sense when the bulb is visible. On a dimmer, choose a dimmable version.
