Can you really save electricity costs, buying a 40 Euro LED-tube compared to a 3 Euro fluorescent tube?
Yes! Especially in companies with long operating times of the lamps.It does not matter whether it is a company with 2 -or 500 employees. Efficiency criteria of T8 or T5 LED tubes are the daily operating-time (uptime or opening hours in retail), the much longer life of LED tubes but also the lower maintenance expense.
Power saving LED tube: 50% or more are possible.
The four standard sizes of fluorescent tubes roughly achieve the following savings:

*The classic fluorescent lamp is always operated in conjunction with a ballast (SG **, ** ECG, CCG **). This consumes additional power and that can account for up to 15 watts per bulb. In the simple replacement of fluorescent lamp with SG against a LED tube, the ballast will continue to operate. It may be more economical to replace the entire lamp.
A personal and professional calculation is necessary. Also helpful is the demonstration of possible alternatives. Please get in contact...
** CCG = Conventional ballast (choke), SG = low loss ballast, Electronic ballast (ECG)
Life with 24-hour continuous use: 3-4 years
A normal fluorescent lamp has an average life time of about 10,000-12,000 hours. LED tubes are usually indicated with 50,000 hours or more.This is also true for the individual LEDs installed. Realistically, is an average life between 30,000-40,000 hours.This is due to the built-in electronic components (capacitors / triacs) that are subject to a quicker wear.
With very cheap LED tubes downtimes after 2-3 months can often be observed. Get advise from a competent contact person, before you purchase.
Amortization: Between 1.5-3 years is normal.
In the commercial sector with weekly working hours from 40 hours to 24-hour shift system can be quite short payback periods of 1-3 years to achieve and achieve an attractive return on the investment thereafter.
In many cases, the power savings is higher than the monthly burden of financing the conversion.

It can be assumed that the price of electricity continues to rise in the future and the calculation thus continued to develop positively. An accurate inventory of existing lighting is important. This is associated with some effort, but it pays to be very working basis.

LED tubes are high-priced: We wait with the purchase!
Without a doubt, rethinking is required! The change of the fluorescent tube as a pure consumables towards greater investment must be explained to the companies. Even with declining LED prices and better products, it is not worth waiting. With the currently high electricity prices, great savings can be achieved, which can eventually pay for itself. An investment in the latest technology allows you to lift a high savings now.
Are the LED tubes amortized and have achieved a significant return, you can you still invest in the next-generation of LEDs.
No delay and switching stability: Fast light without flickering
Compared to the classical fluorescent tube LED Tube will start immediately. Without delay and flicker. Flickering neon lights interfere with the visual perception and have a direct negative impact on the quality of work.Through the direct start, it is also possible to operate the LED tubes directly on a motion detector, because the light is available immediately at full intensity. In addition, LED tubes are insensitive to frequent switching on and off. Even the familiar humming and disturbing noise does not occur with LED tubes.
Without UV light / IR component: Protects goods and goods in the salesroom
LED tubes as a replacement for fluorescent lamps produce no ultraviolet light component. This means that goods, clothing or food do not fade in the retail or age faster. In addition, fewer insects are attracted by LED tubes.
Lower maintenance costs
Through the use of LED tubes also reduce maintenance costs, quite worthy to be in larger companies.The frequent exchange of individual tubes or starters omitted. This includes the robustness of the LED tubes. Compared to the fluorescent housing are better protected against shocks or vibration and not break so easily.
No toxic substances: No bad conscience
Compared to fluorescent LED tubes are not filled with polluting gases to be expensively disposed over the hazardous waste. LED tubes are simply disposed of as electronic waste.
Performance-based electricity bill: base load reduction, power factor and reactive power
For companies with high power consumption is usually not charged per kilowatt-hour special on a performance-based measure of utility. It is calculated with the retrieved peak load, which is calculated mostly from the mean of the two monthly peaks.
With a consistent transition to LED lower your base load permanently.
In companies with a high percentage of machines, the reactive current issue comes into play. The reactive current is compared to the active current provided by the electricity company but can not be used. But it must be paid for it if the factor cos phi is <0.9.
This will be listed separately on the electricity bill. Good LED bulbs have a power factor> 0.95 and are not covered.Traditional fluorescent tubes with CCG have a power factor of 0.3-0.4 and usually have to be compensated by additional capacitors.
Especially in large commercial machines the theme parks reactive current is an important issue to massively save on electricity costs.
