Fluorescent Tubes Buying Guide - Types, Sizes and Uses

How Do I Know What Size Fluorescent Tube I Need?

Fluorescent tubes come in a variety of sizes. Identification of the correctly sized tube will require reference to the code indicating the dimensions. As an example, the T of code T8 refers to the tubed shape, with the 8 referring to the size or diameter. The simplest way to identify the correct size is to read the label situated close to the base of the tube. If you can't read this information, then a measurement should be taken of the tube diameter. The corresponding measurement should be taken in eighths of an inch. The T8 tube has a one-inch (8/8) diameter, while the T5 tube has a 5/8 diameter.

Which Colour Temperature to Pick?

Both the colour temperature and colour rendering index will have a bearing on the appropriate choice of fluorescent tubing. The colour temperature corresponds with the warmth of the light. Warmer tones will have a yellowish appearance, while cooler shades will be relatively bright.

Common varieties of colour temperature include:

  • k ' categorised as an extra warm white, this colour temperature is typically featured in fluorescent tubes designed for domestic use
  • k ' also classified as a warm white, fluorescent tubes featuring this level of colour temperature share lighting properties with halogen lamps
  • k ' coming under the category of bulk standard white, this colour temperature is considered suitable for a wide variety of commercial purposes
  • k ' this variety of cool white is typically applied to office buildings. It is also considered suitable for formal home offices
  • -k ' light generated at this temperature takes on a distinctive bright appearance. It may help in alleviating the symptoms of seasonal affective disorder

The colour rendering index indicates the ease with which colours can be distinguished on the application of different light sources. A bulb with around 80 CRI may be suitable for common domestic applications. However, you should ensure the fitting of a bulb with a CRI of 90 or more given the need for high levels of light.

How Many Lumens are Fluorescent Bulbs?

There will be some variation in the amount of lumens generated by fluorescent bulbs given the type and efficacy of the lamp. However, the majority of fluorescent bulbs generate between 45 and 100 lumens per watt. A 20-watt tube may then be expected to generate between 90 and 100 lumens. The wattage and lumen levels have a direct bearing on running costs.

How Much is a Fluorescent Light Bulb?

There is considerable variation in the pricing of fluorescent light bulbs. However, as a general rule, you can expect to pay under £8 per bulb.

What's the Difference Between a Fluorescent Tube and a Fluorescent Bulb?

The main difference between the fluorescent tube and bulb is in the size. The fluorescent bulb has a distinctive shape and requires special technology for attachment to a standard light socket. It is also common for fluorescent tubing to have a ballast connected with the light bulb. Each offers a good level of energy efficiency.

How Do I Dispose of Fluorescent Tubes?

Fluorescent tubes fall under the classification of hazardous waste due to their mercury content. Care should be taken during the disposal process as part of your commitment to environmental and legal compliance. It will be important to switch off the power source before detaching a fluorescent tube. The tube may then be wrapped in paper or towelling to prevent breakage. The tubing can then be transferred to recycling or hazardous waste disposal in accordance with the legal requirements.

What Do the Numbers Mean on a Fluorescent Tube?

Ideally, there will be legible coding on the fluorescent tube indicating the key characteristics. As an example, you might see the code F32T8. The F in this instance will indicate the fluorescence. The 32 corresponds to the number of watts or length in inches. The T is specific to the tubular shaping. Finally, the 8 corresponds to the diameter in eighths of an inch (this may be represented in millimetres rounded to the nearest millimetre).

What Does a Starter Do in a Fluorescent Light?

It is important to note that some varieties of fluorescent lighting do not feature starters. However, those that do typically have a starter positioned close to the tube socket. The starter will provide voltage in addition to that supplied by the mains. Operating in combination with the choke, this will initiate the ionised path through the tube. The wattage rating of the starter should correspond with that of the fluorescent tube for reliability and longevity.

What is the Brightest Fluorescent Tube?

T8 fluorescent tubing is the ideal option if you want to see a good level of detail. The high levels of colour rendering allow property areas and items to be shown to full effect. These tubes have a life expectancy of up to 15,000 and require a relatively low level of maintenance.

Are T8 and T12 Fluorescent Bulbs Interchangeable?

There aren't any safety concerns associated with the replacement of the T12 fluorescent bulb with a T8. However, you should be aware that the installation of a T8 will result in a shortened lifespan due to the high levels of current running through the tube. It might be necessary to install a different form of ballasting or fixture for operation of the T8 bulb. You may also consider the installation of long tube LED lighting.

Black Light Buyer's Guide () | Glow In The Dark Party Ideas

Buying Black LIghts

What I would have given to get my hands on a black light when I was a kid! Back in the day, the closest we could get was the occasional visit to the skating rink. Here we could marvel at our glowing socks, shoelaces, shirts and the lint on our jeans!

Today, anyone can get their hands on Black Lights. They can be purchased from most party stores, department stores and, of course, online.

Black lights are the most critical part of your glow party. There's nothing that will disappoint more than a weak or ineffective black light effect. With the number of black lights on the market today, it can be overwhelming to find the best lights for your needs.

We hope this guide helps you get the most bang for your buck and choose the best light on the first go.

Best Black Lights from each Category

Read on for a more in-depth look at the available types of black lights.

Best Standard Black Light Bulbs for existing fixtures

A common place to start with black lights is to pick up a UV light bulb from the local department store. While this is often the least expensive, UV light bulbs do not always have the best result. If you know what to look for, there are still some great options. As light bulb technology has improved, the cost of UV light bulbs has come down.

Incandescent Black Light Bulbs

Let me say up front that, generally speaking, incandescent bulbs that are advertised as 'Black Lights' generally do not perform well. They tend to not give off very bright light levels and many do not react to white and fluorescent colors. Obviously, that is the main purpose of using black lights. Many simply give off a bluish light. With so many better options available, we recommend passing on this option. If you do decide to test these out, read user reviews before purchasing.

Compact Fluorescent Black Light Bulbs

A slight step up from incandescent UV light bulbs, fluorescent lights might be a decent low cost option. These also might be available at your local department or hardware store at an affordable price. They won't offer as great of a black light effect as some of the rest in this guide, but can be used in existing lamps or fixtures and are a small financial investment.

LED Black Light Bulbs

Somewhat new to the market, LED black light bulbs are some of the best options to consider. If your budget allows and you have a few existing fixtures, LED UV Light Bulbs is a great way to go. LED light is much more intense than standard bulbs and consume a fraction of the energy.

Fluorescent Black Light Tube Fixtures

Fluorescent tubes are what many think of as the classic black light. This classic may have been one of the first varieties on the market. One of the most popular today is the American DJ 24.

Fluorescent black light tubes give off an even light with great spread. The light bulbs themselves, when illuminated, tend to be less irritating to the eyes. Many fixtures come with an on/off switch and can be plugged into a nearby wall outlet. Keep in mind, if you are not placing a light near an outlet, an extension cord may be needed.

One great option, if your room or space already is existing T12 tube fixtures, is the GE . These work with any mounted or portable T12 fixture.

Black Light LED Fixtures

LED lights are a relatively new technology to consumer grade light bulbs. With the rise in popularity, and reduction in costs, LED lights are showing up everywhere. This is true as well for the LED Black Light.

Being exceptionally bright, lightweight, and low on energy consumption, LED black lights are my top recommendation for your glow party. There are many varieties, styles, and wattages available. Many include convenient on/off switches and some will include mounting hardware.

One thing to keep in mind is, direct light from the LED can be a bit intense, so these are best when used overhead or otherwise out of direct line of sight.

Unique Black Light Options

In addition to traditional fixtures, there are some other creative options that might be a better fit for unique uses.

They come in a variety of lengths, can be cut to size in order to fit unique spaces and most are self-adhesive for easy installation. They are typically made from long lasting, bright LED lights. They are also weatherproof, making them usable outdoors or other unique situations.

Choosing the Best Black Light

When choosing the best black light for your party or event, there are a number of things to consider. Below is a short list of questions to ask that can help you narrow down your search. Keep in mind that black lights, like any light source, are directional and do cast shadow. We advise, for most situations, that at least 2 black lights are used from opposite ends of the party space for the best black light effect.
