How do I know what size light bulb I need?
When it comes to replacing a light bulb, choosing the right size is crucial for both functionality and safety. The size of a light bulb is determined by its diameter, measured in inches or millimeters, and the shape of the bulb. Knowing the correct size ensures the bulb fits properly in the fixture and provides the desired amount of illumination.
Identifying the Existing Bulb Size
To determine the size of the light bulb you need, start by examining the existing bulb. Look for any markings or labels on the bulb that indicate the size, such as "60W" or "A19." These numbers and letters refer to the bulb's wattage and shape, respectively. The shape code, such as "A19," provides the bulb's diameter in eighths of an inch. For example, an "A19" bulb has a diameter of 2.375 inches (19/8 inches).
If the existing bulb doesn't have any size information, you can measure the diameter yourself. Use a ruler or caliper to measure the widest part of the bulb, excluding the base. This measurement will give you the bulb's diameter in inches or millimeters, which you can then match to the appropriate size.
Considering the Fixture and Lighting Needs
In addition to the bulb's physical size, you'll also need to consider the lighting fixture and your desired illumination level. Check the fixture's maximum wattage rating, which is usually printed on the fixture or in the manufacturer's instructions. This will help you choose a bulb with the appropriate wattage to ensure the fixture operates safely.
Think about the room's lighting needs and the desired brightness. Larger rooms or areas that require more illumination may need a higher-wattage bulb, while smaller spaces may be better suited for a lower-wattage option.
Selecting the Correct Replacement Bulb
- Match the bulb's diameter to the existing size, using the shape code or your own measurements.
- Choose a bulb with a wattage that is compatible with the fixture's maximum rating.
- Consider the desired brightness and choose a bulb with the appropriate lumen output.
- Ensure the bulb's base type (e.g., E26, GU10) is compatible with the fixture's socket.
By following these steps, you can easily determine the right light bulb size for your needs and ensure a proper, safe, and effective replacement.
Which is brighter, cool white or daylight?
Is Cool White the same as Daylight? No, Daylight is generally brighter than Cool White. However, at the brightest end of the Cool White colour temperature range, it will still be very bright.

How do I know what size light to get in my room?
For a singular light fixture in a room: Add the length and width of the room in feet, and the resulting number can be the diameter of your fixture in inches. For instance, a room that's 10 feet wide by 12 feet long could accommodate a light fixture with a diameter of around 22 inches.
How do I know what wattage light bulb I need?
Generally speaking, the maximum wattage ratings are printed on the light-bulb sockets themselves. You will see language that reads something like: "Caution: Use only Type A lamp, Maximum 60 watts." In some cases where a fixture has two or more light bulbs, there may be a total wattage rating for the entire fixture.
How do I know what base my light bulb is?
The first letter designates the shape or form of the base, and the number represents the width of the base (normally in millimeters). For example, our 11S14 bulb has an E26 base — the "E" refers to the style which is an Edison screw-in, and the 26 means it has a 26 mm base width.
How do I tell what size light bulb I need?
The letter or letters in a bulb code indicate either shape or special features such as reflector type. Numbers in a bulb code indicate size in millimeters or eighths of an inch. These codes will tell you if a bulb will fit in your fixture and if it's the right shape.
How do I know what wattage bulb I need?
You should check the label on the lamp to find out what lightbulb wattage to use. Most lamps can accommodate a maximum of 60 watts, and you shouldn't exceed the maximum wattage. However, you can use a lower wattage lightbulb than the stated maximum, even if it's brighter than average.
Can I use an E26 bulb in an A19 socket?
Yes, they are interchangeable. The difference between E26 and A19 is simply a matter of size and shape. The base type for standard A19 light bulbs is E26. A19 bulbs have an E26 base and will fit into sockets approved for Edison bulbs.
Can I put LED bulbs in any light fixture?
It is absolutely safe to use an LED bulb in a regular fixture, as long as it has the right base and enough space to dissipate heat effectively.
Are E26 and A19 the same?
All A19 lamps have an E26 base, but not the other way around
The standards that govern the dimensions and design of A19 light bulbs also dictate that it must use an E26 screw base. In other words, all A19 light bulbs also have an E26 base.
How do I know what light bulb to fit?
All light bulbs have a code to identify their type of fitting. The letters tend to stand for the name of the fitting and the numbers are the diameter of the fitting in millimetres. For example, an E27 is an Edison Screw bulb with a diameter of 27 millimetres.
