Why should you stop using fluorescent tubes?

Fluorescent tubes have served as good alternatives to incandescent and halogen in the past. But stop using fluorescent tubes because they have many disadvantages: they start slowly, flicker, make noises, and have a short life and high energy consumption. That’s why switching to LED is worthwhile. Not only are LEDs much more efficient, but they also last up to five times longer than fluorescent tubes. Therefore, do not use the old tubes – this is not only better for the environment, but also for your wallet!

Key facts at a glance:

  • LEDs consume much less energy and last longer than fluorescent tubes
  • Fluorescent tubes may flicker and have a delayed on-time
  • Brightness, color rendering, and luminous efficiency decrease after just a few years
  • Fluorescent tubes contain mercury and must, therefore, be specially disposed of
  • LED panels are an ideal replacement for several fluorescent tubes

How do fluorescent tubes work?

A fluorescent tube is a low-pressure gas discharge lamp. The tube is filled with a gas that emits UV light. Mostly the gas is mercury vapor. In addition, the tube is coated with a fluorescent phosphor. This converts the UV light emitted by the gas filling into visible light.

Stop using fluorescent tubes because of the following disadvantages.

In the following, we explain in detail the dark side of the tubes that why you should stop using fluorescent tubes? You will quickly notice why these bulbs should be a thing of the past:

Power consumption

Although fluorescent tubes have higher efficiency compared to incandescent bulbs: while the luminous efficacy of incandescent lamps is 10 lumens per watt, fluorescent tubes score 7 times higher. Unlike LED, however, they mean high energy consumption. For LEDs, the light output is often over 100 lumens per watt. The difference is quickly noticeable in your electricity bill.


Fluorescent tubes are often distracting due to noise, such as high-pitched whirring. These can come about by so-called resonant vibrations when the socket of the light source starts to vibrate and thereby produces a humming sound. This is particularly disadvantageous in the workplace because it affects the ability to concentrate, productivity and not least the working environment.


We all know it: Fluorescent tubes often tend to flicker. This is not only annoying but can have negative long-term effects on health: excessive eye strain, headaches, and migraines. The bulbs do not comply with the principle of human-centric lighting.

Delay on switch-on

The delay of the light emission when switching on can be very disturbing: it not only costs nerves but often also valuable time and energy. Because the light bulb consumes power immediately after switching on, without exhausting its full lighting potential. You should not waste money on that!

Lifetime and loss of brightness

The life of fluorescent tubes is 7,000 to 20,000 hours, which corresponds to a period of 2 to 6 years. In addition, it can be shortened by frequent switching on and off (especially with low-cost ballasts). Also, the color reproduction may decrease, whereby the natural colors of the illuminated objects appear pale. This is, for example, disadvantageous in the retail trade, where goods should be presented attractively.

The durability of LEDs is ultimately up to 5 times longer than with fluorescent tubes and there are no maintenance and replacement costs on you.


In fluorescent tubes, mercury is obtained. It is indispensable because it is the only material that develops a low but sufficient vapor pressure at the lamp operating temperature. The steam, however, is toxic to humans and the environment. Therefore, the light source must be deposited at special delivery points or recycling centers and must not be disposed of with household waste. This prevents decomposition products released during combustion from entering the biological cycle. Read more about the disposal of bulbs here. In addition, there is a risk when fluorescent tubes break: Although there is only a small amount of the harmful substance in fluorescent tubes, inhalation should be avoided.

so stop using fluorescent tubes and shift to LED LIGHTS.

What are the advantages of LED lighting?

The CREST LED tubes are compatible with each other and can be easily used in your existing frames. They provide reliable lighting, do not flicker and produce no noise. They have a life that can be five times longer than that of a fluorescent tube and their energy consumption is about 60% lower. Reason enough to switch to LED tubes!

Why is an LED panel worthwhile?

An LED panel is a square panel light that you can place as a replacement for up to 4 tubes. If you buy a high-quality panel, you will have much more profit than a tube. Here are the benefits:

Power consumption

Panels consume less energy than fluorescent and even less than LED tubes. A high-quality product needs about 28 W, a device with the same dimensions that use tubes, but 73 W. You can replace a 4-tube socket with just one-panel plate. In this way, the purchase price amortized after a few years and you get your investment back.

Power factor

Fluorescent tubes and LED tubes are operated with ballasts, which always result in energy loss. That’s because the ballast itself consumes energy. Tubes are therefore even less energy efficient. In contrast, panels are equipped with a high-quality driver and have a high power factor. This means that they have a very low energy loss and save you more energy and money with this lighting solution.

Glare ratio

Also, the uniform glare ratio (UGR) is better than any tube. The glare ratio indicates the amount of glare the light causes when viewed. The lower this ratio is, the better. High-quality panel lights have a UGR value below 19, which is considered the best option on the market. In this case, the plates are provided with a diamond layer that reflects the light in all directions. This allows a neutral, evenly divided light.


High-quality surface lights last much longer than fluorescent tubes, whose lifespan is only 7,000 to 20,000 hours. By contrast, most LED tubes are 50,000 hours old. However, this time interval can be shortened if the lamps are exposed to dirt or moisture. In contrast, the area lights last up to 70,000 hours and are not affected by dirt or moisture due to the closed device.
