1. Design & Compatibility
H11 bulbs use a PGJ19-2 base with two closely spaced L-shaped prongs. This compact design makes them suitable for low beam or fog light housings.
9005 bulbs use a P20d base with two straight prongs spaced further apart, designed for high beam housings.
Because of these socket and base differences, H11 and 9005 are not interchangeable. Forcing a 9005 into an H11 socket (or vice versa) can cause electrical mismatch or damage.
👉 Cross-compatibility:
-
H11 is often interchangeable with H8, H9, and H16 bulbs.
-
9005 can cross-reference with HB3 or 9005XS bulbs.
2. Power Consumption & Brightness
H11 bulbs typically operate at 55 watts with an output of around 1,300–1,400 lumens (halogen). They provide enough illumination for city driving without producing excessive glare.
9005 bulbs consume around 65 watts and can output 1,700–2,000 lumens (halogen), delivering a stronger beam ideal for high-speed or rural driving.
Key takeaway: 9005 bulbs are brighter and more power-hungry than H11 bulbs, which explains why they are reserved for high-beam functions.
3. Color Temperature
H11 bulbs (halogen) usually produce a 3200K–3500K warm white/yellowish light. This warmer tone penetrates fog, rain, and snow more effectively, which is why H11s are also used in fog lights.
9005 bulbs (halogen) often fall in the 5000K–6000K range, producing a whiter or bluish light that appears brighter to the human eye.
⚠️ Higher Kelvin ratings may look stylish, but extremely cool-white or blue light can cause glare and eye strain for oncoming drivers.
4. Beam Pattern & Projection
H11 bulbs generate a narrow, downward-facing beam with a defined cutoff line. This minimizes glare to oncoming traffic and makes them safer for low beam and fog applications.
9005 bulbs produce a long-distance, wide projection, excellent for high beam functions where maximum road visibility is required.
This is why most vehicles are factory-equipped with H11 for low beams and 9005 for high beams.
5. Heat Generation & Lifespan
-
Halogen H11: ~270–300 hours lifespan, lower wattage = slightly less heat than 9005.
-
Halogen 9005: ~320–400 hours lifespan, but higher wattage = more heat output.
-
LED replacements: Both H11 and 9005 LED bulbs can last 50,000+ hours, but require good heat sinks or fans for thermal management.
-
HID options: Brighter than halogen or LED, but require ballasts and can run hotter.
6. Vehicle Applications
-
H11: Commonly used in low beam or fog light positions in vehicles like Toyota Camry, Nissan Altima, Honda Civic, Hyundai Elantra, etc.
-
9005: Typically installed as high beams in vehicles like Ford F-150, Chevrolet Silverado, Honda Accord, and many SUVs or trucks.
Knowing which socket your car requires is essential before purchasing, as installing the wrong bulb type can lead to poor beam focus or even electrical issues.
7. Cost & Value
-
Halogen H11 / 9005 bulbs: $15–$30 per pair, affordable but short-lived.
-
LED replacements: $50–$120 per pair, higher upfront cost but lower long-term expense thanks to extended lifespan.
-
HID options: $70–$150+ with ballasts, very bright but more complex to install.
In short, H11 bulbs are the better choice for low beam or fog applications, offering softer, glare-controlled light for city and suburban driving. 9005 bulbs, by contrast, are built for high beam use, delivering higher brightness and longer projection for highways and rural roads. While both are available in halogen, LED, and HID versions, they cannot be swapped without modification, as their sockets and power ratings are different.
