Getting the right fluorescent bulb is important. You need something that will last and something that is right for your particular fixture. You need the right color and tone for your facility. And you need a bulb that is safe and energy efficient. Knowing how to find a fluorescent light bulb that fits all of your needs will save you time, worry and ensure you get the right one every time.
1: Shape, Size, and Base Type
Whether you are buying a fluorescent bulb for the first time or ordering a replacement, the first place you need to look is the fixture. What kind of socket will the bulb be going into? This will give you the key information you will need to start selecting the right bulb. Frequently fluorescent bulbs will have either a single pin or bi-pin (two pin) base type. Some will have a recessed double contact. By eliminating bulbs that don’t match your base type, you are on the right track to finding the right type of bulb.
Also, what is the shape of your bulb? Is it linear, circular or U-Bent? Being aware of the shape you need will save time in the selection process. Most facilities use linear (tubular) fluorescent lights; they are straight in shape and simple. They are the most widely-used type of fluorescent light, and most likely what you will be looking for. However, some companies opt for bulbs that are more unique in shape−like a circle or a U-Bend −to add a certain ambiance or style to their business. These are more popular in places like restaurants and hotels, where character and atmosphere are central to success.
You will also want to narrow down your search by size. First, you will need the diameter or how wide it is around. This is expressed as a number such as T8 or T12. The “T” stands for tubular, and the number is a measurement of the diameter in 1/8" increments. So a bulb with a 1" diameter would be a T8—eight 1/8" increments. Also, be aware of your lamp’s length; a fluorescent bulb can go up to 96".
In this green day and age, we know that conserving energy is of the utmost importance to you. Not only do you want to be aware of your carbon footprint, but energy is expensive and cutting down on usage is a sure-fire way to save money. There are plenty of ways that the right fluorescent bulb can help you achieve that goal without sacrificing brightness or longevity of your bulbs.
How many watts are you currently using? This is an important question to ask. More and more light bulbs are available on the market that use lower wattage without sacrificing brightness. Wattage is the measure of energy used to power your light. Bulb brightness used to be an easy measure of watts−the more watts you push into the bulb, the brighter it will be. But as technology has advanced, bulb manufacturers have been pressed to create lighting options that use less energy (watts) but don’t sacrifice lumens—the measure of how bright a bulb is.
You may find that your old, outdated fluorescent bulbs can be upgraded to lowerwatt bulbs that offer the same or more brightness than you currently have. If this is the case, you may also consider using fewer bulbs altogether. Disconnecting extra fixtures that are not in use can help save energy and money.
3: Tone and Color
Once you have your bulb size and type determined, you must decide the tone and color. When selecting a color, the most important factor is use. What kind of space is the lighting for? Is it for a manufacturing facility? A hospital? A showroom or an office? The type of color you choose will affect how your space looks and feels.
Cool white fluorescent lights are most common in offices, hospitals and manufacturing facilities. They offer optimal light for these busy operations, and the color allows for inspecting the small details in this kind of work. Residential lighting, restaurants and hotels benefit from a warmer white that sets a comfortable and homey tone. The mid-range white is right for areas such as retail outlets, showrooms and supermarkets.
