What Size Light Bulb Do You Need

The light bulb size is the most critical piece of information when selecting new bulbs. That's because, the cap or base joins the light bulb to the socket to provide an electrical connection and power your bulbs, while the shape you select need to fit into your fixture and what kind of atmosphere you're trying to create. So, it's quite important to ensure what size of the new bulb you need before you buy.



However, with a wide variety of bulb bases and shapes available, it's difficult to know which one is right for your fixture, which also makes purchasing a bulb with the wrong size a common mistake. Hence, in an attempt to help you find the right bulb size for your fixture, we've created a guide to show you what measurements you need to take, and where exactly to start your measurements from. Let's take a look:

How to measure light bulbs?

How to Measure Light Bulbs


When you choose the new bulb that is close in size to your old one, you shouldn't have any problems in fitting them into your lighting fixture, therefore; just make sure you keep these light bulb measurements handy:

Measure the Bulb
Measure the Base





Measure the Bulb

When measuring the bulb, there are two types of measurements you should pay attention to:


The Bulb Length

When you are measuring the length of your light bulb, ensure that you have measured it from the top of the glass or plastic bulb to the very tip of the base using a ruler or measuring tape. Then, remember that what measurement you need to take is the bulb’s height, but not its surface length, so keep it taut rather than following the edge of the bulb if you are using a soft measuring tape. Plus, most of you may be wondering that how to measure the length of fluorescent tubes, just simply take your measurement from the tips of the pins in either end.


The Bulb Width

Each light bulb has a code that indicates its shape and diameter at the widest point. For instance, an a19 bulb indicates that it's a classic A-series light bulb with a diameter of 19 eighths of an inch (2.38 inches or 60.33mm). Hence, to take the correct width measurement for your bulb width, you must measure it at the widest point, which will vary based on the type of bulb you choose, like the following picture:





Measure the Base


Whatever type of base a light bulb has, a bayonet or screw, their base are measured in millimetre and will be labelled using a code similar to the one used for the bulb. For example, a standard light bulb base is an e26 bulb, which means that the base is an Edison screw base that measures 26mm.

Purchasing a bulb with the wrong size is a common mistake, but it can be solved when you having taken the measurement. Then, you may know that what size of bulb need to take, so it must be your time to shop the right bulb from LOHAS. From color changing light bulb to dusk to dawn light bulb, there is always the one from LOHAS that will meet your need.


Light Bulb Base Types from LOHAS LED


Lighting Tips: Each of the bulb base type has an base code follows a letter-number-letter format:
The first letter(s) indicate the type of base or cap, such as Bayonet or Edison.
The numbers indicate the diameter of the base or the distance between the pins in millimetres.
The last letter is optional. It indicates the number of pins or contacts the base has and can usually be found on architectural and striplights.


Edison Screw Base - E26 LED Bulb & E12 LED Bulb


Most home light bulbs are designed with a screw in base, which have a threaded base that screws into the fixture to securely hold the bulb. These are called "Edison" bases, after the famous inventor, and . In LOHAS LED, the most common is the e26 base, which is what is on most screw in home light bulbs, regardless of what technology (Incandescent, LED, Fluorescent, etc.) they are. The e26 light bulb just stands for the bulb has an Edison base and the numerical part is the diameter of the base in millimeters. Then, always keep our users in mind, in case of you'll likely have some smaller led candelabra bulbs in some chandeliers around the house. These are also screw in lamps but are a smaller diameter, usually e12 bulb from LOHAS.

Pin Base - GU10 Bulb, GU24 Bulb and G9 Bulb


Pin base is the other common light bulb base, which is usually only found on small recessed can lights or track lighting and are either GU10 or GU24 or G9 base. Similar to the other base types, the numbers just stand for the distance between the two pins, measured in millimeters. For example, the letter "G" indicates a bi-pin or two pin base, but because GU10s have a twist and lock mechanism, they are classified as a type of bayonet base. GU10s have two pins that are 10mm apart and extend 7mm from the base.


Light Bulb Shapes from LOHAS LED


Now that you know what fitting, colour, then you need to decide what shape of bulb you'd like. Like what we mentioned above, a number on a light bulb shape stands for how many eighths of an inch in diameter it is. For example, an a19 light bulb is 19-eighths of an inch or 19/8" in diameter. To determine a light bulb size, use the full size scale shown (calibrated in eighths). It's pretty easy to convert once you get the hang of it.

Nowadays, the most common bulb shape is known as an A-Lamp and candle, and what you'll mostly see what is known as an a19 bulb with an e26 base and candle light with an candelabra base. So, to fit this accustom, we have also designed the bulb in A shape and Candle shape.
