Led bulbs are also more durable than fluorescent bulbs due to their compact size. While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
In short led and cfl as technologies do not have a difference in brightness intrinsically.
Compact fluorescent light bulbs vs led. They also now come in round and flame shapes. Lumens measure the brightness of the bulb. Led light emitting diode bulbs are a newer technology.
4000 lumens divided by 90lm w led efficacy rating will give you 45watts. 4000 lumens divided by 50lm w cfl efficacy rating will give you 80watts. Both cfl and led bulbs are measured by lumens not watts.
Fluorescent bulbs are generally less expensive than led options but they have a shorter lifespan and must be carefully recycled due to their mercury content. After being switched on these tubes light up immediately with their full light output without flickering. Because of this led s are far more energy efficient than incandescent or fluorescent lights which emit light in a much wider band of wavelengths.
Led tubes have almost only advantages compared to fluorescent tubes. The cfl bulb is known to reduce replacement costs and is an energy saver. A light emitting diode or led for short is a lamp that emits light in a very narrow band of wavelengths.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15. An led fixture uses less power in our example 35watts less to produce the same amount of light as a cfl bulb. Cfl compact fluorescent lamp bulbs are commonly manufactured as a spiral tube connected to a screw in ballast or base.
Cfls and fluorescent bulbs do contain small amounts of mercury that can be poisonous if the bulb breaks. A single cfl and led bulb might have the same lumen brightness output but vary greatly in the amount energy needed to generate that level of brightness. However its average life span is much less than that of an led bulb.
Newer technology replaces the curly light bulb with one that looks like the traditional incandescent bulb. Lumens is best described as the measurement of light. In terms of led vs cfl in energy efficiency both cfl and led bulbs are good for conserving energy with led conserving a bit more.
Leds do not contain mercury or harmful gases. Cfl and led bulbs use up to 80 percent less energy than their incandescent counterparts and can last up to 25 times longer. Now that you understand the basic differences between each bulb we can compare the two and pick a winner.
Unlike traditional light bulbs energy efficient light bulbs are measured in lumens rather than watts. Brightness is determined by lumens. The environmental balance is also very positive due to the absence of mercury and the savings of 40 60 in energy consumption.
Leds require less wattage than cfl for the same amount of light.
