An old habit is hard to break. That might be why so many Colorado households are still using inefficient light bulbs. Most of us grew up with incandescent lighting.
You know, the old-fashioned light bulb with the wire filament inside. Looking back, the whole concept seems so old school. Basically, we pumped that filament with so much energy that the heat produced a bright, blaring light. CFLs are significantly more energy-efficient than the old incandescent bulbs.
The specifics of light production within an LED and CFL bulb can get fairly technical, but this page is designed to make the distinction quick and easy to understand.
CFL bulbs have a small tube within them. For this reason, luminaires in retail are labelled with the efficiency classes of the light sources which can be used for their operation.

Energy efficient light sources The central component of any lighting installation are its light sources, since they deliver the "raw material" which is then to be further distributed and controlled.
For efficient light generation, it is important to observe the following: A high luminous efficacy specifies how much light lumen is available in connection with the utilised connected load watt. Energy labelling When offering lamps in retail sales today, retailers are legally obliged to clarify to the technically untrained customer how well the lamp is utilising electrical power to generate light.
Lamps to be labelled since the amendment in fundamentally include all lamps for household and professional use, such as: incandescent lamps, fluorescent lamps, high-intensity discharge lamps, LED lamps and LED modules. The following are exempt from labelling: lamps and LED modules with a luminous flux below 30 lumens lm ; lamps and LED modules marketed for use with batteries; lamps and LED modules marketed for applications where the primary purpose is not lighting; lamps and LED modules marketed as part of a luminaire and not intended to be removed by the end user, except when they are offered or displayed to the end user in a separated fashion e.
The following are exempt from labelling: all lamps with a luminous flux in excess of 6. UV, IR, black light and germicidal lamps as well as all lamps for special applications and lamps predominantly used in commercial settings such as high-intensity discharge lamps and low-pressure sodium vapour lamps.
LEDs come in a variety of colors, and some bulbs can be tuned to different colors or different hues of white light. Some are dimmable or offer convenient features such as daylight and motion sensors.
LEDs work well indoors and outdoors because of their durability and performance in cold environments. Look for LED products such as pathway lights, step lights, and porch lights for outdoor use. You can also find solar-powered LED outdoor lighting. The cost of LED light bulbs has decreased dramatically since they entered the market and prices are expected to come down further as more products become available.
