What Are the Different Types of Fluorescent Bulb Holders?

Table of Contents

When it comes to illuminating spaces, fluorescent bulbs have been a go-to choice for many because of their energy efficiency and long lifespan. But what often goes unnoticed is the humble bulb holder that securely houses these lights. The functionality and safety of the entire lighting system depend significantly on the type of bulb holder used. Yet, with the wide variety of fluorescent bulb holders available in the market, choosing the right one can be a bit perplexing.

In essence, there are four main types of fluorescent bulb holders, namely, the starter tube holder, the G13 lamp holder, the T5 light holder, and the T8 holder. These types are classified based on the bulb they are designed to accommodate. Each has its unique features, specifications, and applications, ensuring that there is a bulb holder suitable for every lighting need.

Let’s shed some light on these different types of fluorescent bulb holders and how they contribute to a well-functioning lighting system.

What is a Starter Holder?

A starter holder is a type of fluorescent bulb holder that is specifically designed to house the starter, a crucial component in certain types of fluorescent lights. The starter aids in initiating the discharge process in the gas within the fluorescent bulb, hence its name.

A starter holder is often constructed from robust materials that can withstand heat and electrical stress. It typically features a two-pin design that accommodates the starter. While less common in modern lighting applications due to the shift towards electronic ballasts, starter holders are still essential in older lighting systems that use electromagnetic ballasts.

What are G13, T5, and T8 Holders?

G13, T5, and T8 holders are types of fluorescent bulb holders named after the bulbs they accommodate. The ‘G’ in G13 stands for the type of base used (bipin), and ’13’ indicates the distance in millimeters between the two pins on the bulb base.

G13 holders are compatible with T8 and T12 bulbs, which are commonly used in commercial and industrial lighting applications due to their high light output.

On the other hand, T5 holders are designed for T5 bulbs, which are smaller in diameter than T8 and T12 bulbs. T5 bulbs and their corresponding holders are ideal for applications that require compact yet efficient lighting solutions, such as under-cabinet lighting or display case illumination.


T8 holders are somewhat similar to G13 holders as they also accommodate T8 bulbs. However, these holders often feature a rotary locking mechanism that provides a more secure fit compared to the push-fit mechanism of G13 holders.

Secondly, consider the application – whether it’s for residential, commercial, or industrial use, and the specific requirements of the space to be illuminated.
