How Does A LED Fluorescent Light Compare With A Compact Fluorescent Light?

For many years the CFL (Compact Fluorescent Lamp) was the alternative choice for anyone who wanted to reduce the energy consumption of their household lighting. The advent of super energy efficient LED fluorescent light has complicated this matter as consumers are forced to weigh up the pros and cons of both of these bulbs. But which in fact is better?

1) A typical CFL will use between 9 and 11 watts in power. This is a good improvement over traditional incandescent bulbs, but not as good as an LED. LED light bulb uses 4.5 watts in power, which is not only a vast improvement over the old incandescent, but is also better than the CFL.

2) Most CFLs have a quoted life span of about 5,000 hours, but you need to be wary. Most retailers will exaggerate this figure and most CFLs will use a large percentage of their luminosity before the end of their life span. On the other hand a LED light tube has a rated life expectancy of 30,000 hours, about 6 times longer, and they will remain consistently bright for their entire life span.

3) One of the biggest issues with CFLs is their safe disposal. CFLs can not be included in normal household waste or recycling because they contain a small amount of a harmful substance called mercury, which is important in their operation. If a CFL breaks this substance is released and can cause serious environment damage. In order to recycle them safely they need to be taken to designated recycling centres for hazardous waste.

The LED fluorescent tube light contains no harmful substances at all. They also don't heat up. This makes them very safe to handle and recycle. Even if they break, which is unlikely as they are quite durable, they can be swept up and thrown away. Most retailers also provide their own recycling service under the Waste Electronic and Electrical Equipment (WEEE) Directive. Contact them to find out.

4) A notorious issue with the CFL is the time it takes to reach full luminosity. Some models may take a couple of minutes to reach full brightness, which can be a real headache. Some new models have overcome the issue, but the light they produce is still quite unnatural and achieves poor colour rendering. The LED fluorescent light up instantaneously. They also produce a clear, natural looking light.

5) CFLs are available in a limited range of fittings, shapes and sizes. In addition to this, research and development into CFL technology is much slower than LEDs. LED fluorescent tubes are available in a a few range of styles.

6) Finally, the CFLs are still cheaper than typical LED fluorescent lights, but the price of the latter is gradually coming down, and it won't be long until it reaches a level that is viable for both domestic and commercial consumers.
