LED - FAQ  Questions and Answers

The most common customer questions and our statement

The LED lights but not yet pay off?

With a daily useful life of more than 8 hours, the conversion count
conventional lighting on an LED in a period of less than 3 years, and leads subsequently to significant cost savings of up to 70%. (Lifetime up to 20 years at 8 hours of daily use)

LED lights are still too expensive to be safe even cheaper?

Even if one would speculate that LED lights would be cheaper by 50% over the next 3 years, the shift of the investment is not worthwhile. Today's LED acquisition costs are already within 3 years cost savings that are higher than the cost. Thus, the hitherto neglected cost savings can not catch up even in the event of a sharp fall in prices.

You need incentive to switch from conventional lighting to LED a larger number of LED Lights?

In the conversion to LED can 1: 1 exchange ratio to obtain an equal or bright or even brighter light. For example: A powerful 1.50 m LED tube brings a luminous flux of up to 3,300 lumens with a power consumption of only 30 W. Such a tube is suitable even for ceiling heights of 10 m. For offices 1.50 m LED tubes with 2500 lumens and 23 W power are sufficient.

A conversion to LED is expensive?

In the majority of existing lighting installations with fluorescent tubes (CCG / LLG), conversion is very simple. It is only the existing tube to replace by a LED tube and replace the existing starter against a supplied LED-starter. This can be done by any person who else makes the exchange of tubes.
Only when lights are installed with electronic ballasts, you must be examined in more detail how the conversion is performed most sense. Manufacturing or logistics halls are radiators installed with HPS or mercury vapor lamps, so it is advisable to replace the entire radiator against LED lights.
The use of LED bulbs in normal lamps, however, is not recommended due to technical reasons.

If the LED light output sufficiently in high ceilings?

LED high bay luminaires are available in various levels of performance and exceed the performance of conventional lamps often significantly. Crucial is next to the LED chip used, the quality of the power supplies and the sophisticated design of the luminaire overall system.
The system power is the key! Powerful LED lamps have since proved itself to illuminate large outdoor areas (eg container terminals) at mounting heights of 30 m.

LED light is still uncomfortable?

LED light now exist with different color temperatures (= light colors). From warm / yellowish light (about 2700-3300 K) neutral white light (approximately 4,000-5,000 K) to daylight / cool white light (about 5300-6500 K).
LED light does not contain infrared and ultraviolet rays and is not recommended in a report by the European Commission itself for sensitive people.

Watt is still Watt - all lights therefore have the same power?

Example: 50 W says simply stated that the lamp in question has an energetic power of 50 W, ie, 50 watts of electricity. What brightness produces the light, can be inferred only from the lumens information. This can, for example, at 50 W 3,900 lumens or be very effizente and powerful 6000 lumens. In other words, a certain light output can be achieved with higher or lower energy performance. The measure lumens per watt brings more clarity. Would at the same lumen claim does better than 40 W 50 W, as significantly more energy efficient!

With tubes you have only attention to the length?

Especially with LED tubes, it brings with it the number of offers that significant differences in quality exist. Not only the light output varies greatly here.
In a tube with 1.50 m length, the move from a modest 2,000 lumens to 3,600 lumens bright. It is important not least that the tubes totaling the current security regulations, which unfortunately is not the case with all offers on the market. The safest manage the orientation if you look at LED tubes focused exclusively on VDE certified products and for your own safety can hand over a copy of the test certificate together with the offer.

Conversion to LED still has time, why should I invest today already?

Due to the "EuP Directive for office, industrial and street lighting" must inefficient mercury vapor lamps, metal halide lamps and Hochdrucknatriumdampflampenn that do not comply with the applicable energy efficiency requirements, from 01.01.2015 no longer be placed on the market. The inefficiency of this high-pressure discharge lamps can be a storage of bulbs to use extension economically not make sense. Thus, a timely conversion is required.

An LED retrofit safe cost us cash?

Apart from the fact that in the first year often more than 1/3 of the investment costs are recorded by cost savings, there is the possibility of investment financing through leasing. This results from the very first month of retrofitting a liquidity surplus. That which are reduced by the conversion to LED monthly electricity cost plus lease payments are together less than the cost of electricity paid monthly before
