Command Fitness Leaders (CFLs) play an integral part in the overall fitness and readiness of Sailors. CFLs are not only responsible for conducting the bi-annual PFA for their commands, but also provide exercise programming and guidance throughout the year to ensure the members of their command maintain physical readiness. All CFLs must be trained and certified through the five-day Command. CFL Season has not started! Please give an overall site rating. In Canadian football, the point scoring is the same as in American football: touchdown (6), convert (1 or 2), field goal (3), and safety (2). In addition to the above, there is one more way to.
CFLs produce light differently than incandescent bulbs. In an incandescent, electric current runs through a wire filament and heats the filament until it starts to glow. In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.
CFLs need a little more energy when they are first turned on, but once the electricity starts moving, CFLs use about 70% less energy than incandescent bulbs. A CFL's ballast helps 'kick start' the CFL and then regulates the current once the electricity starts flowing.
This entire process typically takes 30 seconds to 3 minutes to complete, which is why CFLs take longer than other lights to become fully lit. CFLs with decorative covers like globe or reflector shapes have a unique design challenge that results in the tradeoff of a slower warm up time, which is why these CFLs take longer than bare spirals to reach full brightness.
Older CFLs used large and heavy magnetic ballasts that caused a buzzing noise in some bulbs. Most CFLs today — and all ENERGY STAR certified CFLs — use electronic ballasts, which do not buzz or hum.

Cfl Point Systems
In Canadian football, a single (also called a single point, or rouge) is a one-point score that is awarded for certain plays that involve the ball being kicked into the end zone.
Rules[edit]
A single is awarded when the ball is kicked into the end zone by any legal means—other than a convert (successful or not) or a successful field goal—and the receiving team does not return (or kick) the ball out of its end zone.[1] A single is also scored if the kick travels through the end zone, or—other than on a kickoff—the ball goes out of bounds in the end zone without being touched.
A single is indicated by the referee raising his right arm and index finger.[2] After conceding a single, the receiving team is awarded possession of the ball at its 35-yard line.
Singles are not awarded in the following situations:
- if a ball is downed in the end zone after being intercepted in the end zone
- if a ball is fumbled outside the end zone
- if the kicked ball hits the goalposts (since the 1970s; before then it was a live ball)
- when a kickoff goes into the end zone and then out of bounds without being touched
In each of the above cases, the defending team is awarded possession of the ball at its 25-yard line.
In the official rules, the single point is also called a rouge,[3]French for 'red'. The origin is unclear; one theory is that a red flag was used to signal the score in the game's early days.[citation needed] Another is that, because the conceding team had a point deducted from its score on the play in earlier days, the tally was called a 'red point'.[citation needed]
There is one other way to score one point on a gridiron football play, other than a routine extra point. If either team scores a safety on a conversion attempt after a touchdown, one point is awarded.[4]
Canadian Football League[edit]
The Canadian Football League (CFL) has discussed abolishing the single, but proposals to do so have been rejected. A 2005 proposal to reduce scenarios resulting in a single on missed field goal attempts was also rejected.[5] A less-sweeping proposal would see the single eliminated on punts and field goal attempts that travel through the sidelines of the end zone – such a change would eliminate the 'consolation' point for a failed coffin corner attempt. Other proposals would have the rouge scored only on kicks scrimmaged from beyond a certain point and/or are otherwise deemed 'returnable', having touched the end zone or a return team player without being advanced back into the field of play.
The lowest scoring game in CFL history, a 1–0 victory by the Montreal Alouettes over the Ottawa Rough Riders in 1966,[6] had no scoring except for a single in the fourth quarter on a missed field goal attempt.[7]
Other football codes[edit]
In American football, Canadian football-type singles are not used. Receiving teams are allowed to down the ball in the end zone for a touchback, and kicking the ball out of bounds through the end zone also results in a touchback; in either case, the receiving team receives possession of the ball at either its own 20- or 25-yard line, depending on the specific level of play.
Some indoor American football leagues have used the single, namely the National Indoor Football League, the American Indoor Football Association and the Professional Indoor Football League, all now defunct. The single was applied only on kickoffs, and was scored if the receiving team failed to advance the ball out of the end zone when kicked. The NIFL and AIFA also allowed a single to be scored by kicking a kickoff through the uprights (as in a field goal); this type of single was nicknamed (and was later codified in the AIFA rules as) an uno,[8] from the Spanish word for the number one.
The concept of the rouge dates back to several public school sports played in England from the early 19th century. In Rossall Hockey played at Rossall School, and the Eton field game, both of which are still played today, a rouge can be scored after the ball has gone into the local equivalent of the 'end zone' after striking another player. The Sheffield Rules, a 19th-century code of football, also used the rouge as a secondary scoring method, as did the first rules formulated by the Football Association in 1863.[9] The behind used in Australian rules football is similar in concept to the Canadian single (worth one point whereas goals are worth six), as is the point in Gaelic football, hurling, and camogie (where a ball into the net scores three points, while a ball passing over the crossbar scores one).
