What is a CFL bulb?

CFL bulbs differ from usual light bulbs because they lack a filament, instead using pressurized gas in a fluorescentcoated tube to produce light. They are also sometimes referred to as compact fluorescent bulbs or spiral light bulbs.

What are the pros and cons of CFL bulbs?

They are very energy efficient and work longer than incandescent light bulbs but contain mercury vapour which makes them hazardous if the tube breaks. CFL bulbs also require an electronic ballast to operate, which adds an extra failure point compared to most other common household light bulbs.

Can you replace CFL bulbs with LEDs?

LED bulbs with a matching wattage rating and base type can replace similar CFL bulbs in most fixtures.

Why would I choose CFL bulbs over other light bulb types?

Energy savings is the main reason to choose CFL bulbs, as they consume much less electricity than incandescent bulbs and work for much longer before failing.

How do I know which CFL bulb I need to buy?

You will want to make sure to match the wattage of the CFL bulb with the fixture where you'll be using it. If size is an issue, you'll want to check that the CFL bulb will fit.
