What is a CFL?

CFL is an acronym for compact fluorescent lamp. CFLs are fluorescent light bulbs that consume up to 75% less energy than traditional incandescent light bulbs and act as direct energy-efficient alternatives. 


How do I safely dispose of a CFL when it burns out?

Do not dispose CFLs in regular household trash. It is best to recycle your CFL. Many local hardware stores and communities have different recycling programs for CFLs. That way the bulbs will then be managed responsibly by an environmental management company who will coordinate CFL packaging, transportation and recycling to maximize safety and ensure environmental compliance. The EPA has a list of recycling centers that can be found here: http://earth911.com/


What should I do if I break a CFL?

The EPA recommends that if a CFL breaks carefully sweep up all the fragments – wipe the area with a wet towel and dispose of all fragments, including the used towel, in a sealed plastic bag. Follow all disposal instructions. If possible open windows to allow the room to ventilate. Do NOT use a vacuum. Place all fragments in a sealed plastic bag and follow disposal instructions. You can find full instructions here: http://www.epa.gov/cfl/cflcleanup.html


How long should my light bulbs last?

Greenlite adheres to an industry standard for rating light bulb life called “rated life.” All of our packaging shows the average rated life of that specific bulb. All light bulbs are tested to determine what their rated life will be. The time that half of the test sample fails is considered rated life. By definition, some lamps will fail before their rated life and some will operate beyond their rated life. Keep in mind that different styles of light bulbs can have different rated life. Using a bulb in an incorrect application can also have an impact on the life of the bulb. Application information can be found on the bulb packaging. 


How does a CFL work?

Compact fluorescent light bulbs are extremely more energy-efficient than traditional light sources due to the method in which they produce light. Incandescent light bulbs produce light by heating the filament inside the bulb, which makes the filament white-hot. This method is wasteful as a lot of energy goes toward creating heat, not light. CFLs, on the other hand, produce invisible ultraviolet light when excited by electricity. This UV light turns into visible light as soon as it hits the white coating inside the bulb. Therefore CFLs are much more energy-efficient!


Where should I use CFL bulbs?

CFLs can be used in any residential or commercial application. Greenlite provides premium CFLs in a variety of wattages, shapes, sizes and colors to replace every incandescent or halogen bulb. CFLs are particularly practical for use in areas where light bulbs are on for many hours to reduce your energy consumption and thereby energy bill drastically. Additionally, CFLs are especially great for hard-to-reach areas as they rarely have to be replaced due to extremely long lives. 


Can I use a CFL with a dimmer switch?

Greenlite has a vast collection of dimmable CFLs. Please visit the “Our Lights” section of our website to find the right CFL dimmable product for you. 


Can I use a CFL with my 3-way lamp?

A regular CFL can be used with a 3-Way fixture and not damage the bulb. In this case, the bulb will only operate on the middle setting. A specified 3-Way CFL must be used in order to achieve the 3 different levels of brightness. Greenlite has a number of 3-Way CFL models; please visit the “Our Lights” section of our website to learn more. 


Can I use a compact fluorescent light bulb in an enclosed light fixture?

CFLs are not intended for use in fully enclosed fixtures. For recessed applications, please explore Greenlite's CFL Reflectors collection.


Can I use a CFL bulb outside?

For outdoor applications, only CFL Par bulbs designed for damp locations are recommended. No CFL should ever come into direct contact with weather. 


Can I use a CFL in applications where I will be turning the lights on/off frequently?

Compact fluorescent light bulbs work best if they are left on for over 15 minutes each time they are turned on. These types of lamps can take up to 3 minutes to warm-up. Warm-up will probably not be noticeable from a user stand point, but the lamp needs to warm-up in order to reach the point of most efficient operation. Frequently switching them on and off will shorten the life of the product. If the life of the lamp is shortened significantly, you will not reap the financial benefits (includes energy & life of lamp), that are common to CFL lamps.
