The H4, H7, H11, H8, H9, H10, H1, and H3 are various types of LED headlight and fog light bulbs commonly used in cars. These bulbs are designed to replace traditional halogen bulbs and offer several advantages such as increased brightness, longer lifespan, and lower power consumption.
The "H" in the model names refers to the bulb's type, which indicates its base type and the arrangement of the filaments. The numbers following the "H" indicate specific bulb models. Here's a brief description of each type:
H4: The H4 bulb is a dual-beam bulb, meaning it serves as both the high beam and low beam headlight. It has three filaments: one for the high beam, one for the low beam, and one for the parking light.
H7: The H7 bulb is a single-beam bulb and is typically used as a low beam headlight. It has a single filament and does not support high beam functionality.
H11, H8, H9, H10: These bulbs are all single-beam bulbs commonly used as fog lights or auxiliary lights. They have a single filament and do not support high beam functionality.
H1, H3: Similar to the H11, H8, H9, and H10 bulbs, the H1 and H3 bulbs are also single-beam bulbs used as fog lights or auxiliary lights. They have a single filament and do not support high beam functionality.
The light output of these bulbs is measured in lumens (LM), and the power consumption is measured in watts (W). The description states that the bulbs have a brightness of 12,000 lumens and a power rating of 80 watts. This indicates that they produce a high amount of light output while consuming relatively more power compared to lower wattage bulbs.
These LED bulbs are designed for use in a 12-volt automotive system, which is the standard voltage in most cars. They are intended for driving and running lamps, providing improved visibility and enhanced lighting performance compared to traditional halogen bulbs.
It's important to note that specific product features and specifications may vary among different manufacturers and models, so it's advisable to refer to the product's documentation or specifications for precise details.
