Abstract
When choosing the best led headlight bulbs, a lot of confusing information might impact your shop. For example, light bulb base sizes, heat tolerance, voltage, and dimmability. What are light bulb bases, how long do led bulbs last and how do these affect you when buying a light bulb? The following will explain and discuss those influences on choosing the led light bulbs.
Light bulb base sizes
There are several different light bulb base types for light depending on the application, fixture, and region. This article will explain one typical base size of light bulbs: Screw Bases.
The most common screw bases call Edison Screw Bases (E26 bulbs, lamp for E27 bulb, E12, etc.).
The Edison Base head is a type of light bulb head that uses a threaded device to secure the bulb to the fixture and is very common in life, such as E26 base. The bulb is named after Thomas Edison, who popularized the design.
To be more specific, the E stands for the abbreviation of the bulb type, and the number represents the diameter in millimeters. Below is the led Edison bulb base sizes and replacements chart for buyer's reference when buying:
| Light Base | size | Common Application |
| E12 bulb | 12mm diameter | Chandeliers, decorative fixtures, and small lamps |
| E14 Bulb | 14mm diameter | Europe small or decorative light fixtures |
| E26 Led Bulb | 26 mm diameter | Lincandescent, LED and CFL bulbs. The most common lamp base type for residential lighting in the United States. |
| E27 Bulb | 27 mm diameter | Compatible with most lamps and lighting fixtures in Europe. |
| E39 Bulb | 39 mm diameter | HID lamps and some large LED lamps. |
| E40 Light Bulb | 40 mm diameter | Street lights, large floodlights and other high wattage lighting applications. |
How to purchase a bulb according with screw base or how to replace headlight bulb?
Take 2.25 inch base path lights as an example. If you want to buy led 2.25 inch base path lights,the most suitable choice is E26 base, because the E26 light bulb is a standard medium-sized base commonly used in most residential and commercial lighting fixtures. It fits most fixtures with a 2.25-inch base, such as LEDs, incandescent and CFLs, and many other bulb types.
Heat tolerance
As an enclosed luminaire, LED bulbs generate a small amount of heat during operation. If they are placed in a fully enclosed luminaire without proper ventilation, the heat will gradually build up and slowly shorten the bulb's lifespan, light stability and brightness, and caused led light bulb flickering. In particular, not all LED bulbs and its base can cope with this situation, so it is important to check whether the bulb is suitable for use in an enclosed luminaire.
At this point it's important to make sure that the bright LED light bulbs you're buying is heat resistant enough to cope with enclosed environments, and you can check with your buyer to make sure you're getting the right led floodlight bulb for the job!
Voltages
Most LED bulb base size are designed for standard voltages (e.g. 120V or 230V) or low voltages (e.g. light bulb standard base 12v 20 watts). If the voltage of the bulb does not match the fixture, the bulb may not work properly or may be damaged. Specifically, typically, bulbs with heads such as e26 bulb base are designed for 120V (US) or 230V (Europe). However, if your fixture uses a transformer (such as an MR16 or GU10 bulb in low voltage track or landscape lighting), be sure to select LED light bulb bases that are rated for low voltage (12 V.) These bulbs are designed to work with transformers of specific voltages.
In addition, there are LED bulbs that can be converted to the correct type and level of power using an electronic driver. If you are replacing a conventional bulb with an LED, or if it does not fit into your existing fixture, make sure your fixture driver is compatible with the voltage requirements of the LED.
Dimmability
If dimmable led light bulbs are required, standard light bulb base without dimming capabilities will not work properly with dimmer switches, often resulting in flicker or poor light quality. Traditional dimmer switches (for incandescent bulbs) may not work well with most standard light bulb base size. So look for an LED-compatible dimmer or something and a more advanced driver to handle the dimming function. And different dimmable LED bulbs may have different dimming ranges. So be sure to find a compatible LED bulb and its base to use all its functions properly.
Now, you can start purchasing the LED Light Bulbs you need!
