Frequently asked questions

In terms of industrial lighting it is all too easy to lose the forest for the trees.

Manufacturers and suppliers show long product lists, capabilities, technical data sheets and labels.

Yet it is not clear to you what is the best solution or investment.

How can you decide with confidence to deal with someone trusting that you end up with the lighting solution that is best for you?

To help answer that question you will find a series of frequently asked questions and their answers below.

FAQ

What does it cost? Why is this a good investment?

You pay an item price per Omikron fixture (delivered or installed if you wish).

For this price you get:

• The highest light output

• The best light quality

• The highest return

• Included cables and fasteners

• Simple installation and maintenance

You do not pay for what you do not need or what you cannot recoup:

• Dimming

• Complex controls

• Hidden costs

By focusing on efficiency and quality each Omikron fixture earns back its purchase cost at least 5 times over during its lifetime.

A fluorescent fixture costs me € 60 per year in energy consumption. Is that right?

Depending on the number of usage hours per year, this is indeed correct.

The following calculation, based on a realistic assumption for the number of hours, makes this clear:

Power fluorescent TL fixture: 135 W (0,135 kW)

Usage time: 10 hours / day

Working days: 220 days / year

Price: 0,20 € / kWh

Total energy cost per fixture:

59,40 € / year   (0,135 kW x 10 h/d x 220 d/y x 0,20 €/kWh)

If you have a workshop with 100 fluorescent fixtures you pay:

5940 € / year.

The same light output with 50 Paradin Omikron fixture will only cost you:

1320 € / year

This difference increases quickly as the number of usage hours increases.

What makes the products of Paradin unique?

Paradin develops its products with a very clear vision without compromise.

We deliver LED fixtures with a very high light output and maximum efficiency (up to 160 lm / W) at a competitive price.

The design is practical, flexible and of high quality.

The brightness, color temperature and dispersion are chosen for optimum performance in a professional setting.

They meet all industry standards for harmonic distortion and powerfactor (cos(?)) as well as demands for protection and safety class.

No long list of product variations that complicate choice of purchase, maintenance or future expansion.

No standard extras (such as complex control and dimming) which reduce efficiency and increase the likelihood of errors and costs.

Multifunctional and expandable thanks to plug and play accessories such as covers or motion detection.

Each fixture earns a multiple of its purchase price during its lifetime.

Good for your wallet and the environment.

Which warranty does Paradin provide on its products?

Paradin provides a 5-year warranty on the entire Omikron fixture.

In case of defect you simply receive a replacement.

Moreover, because of the easy plug & play installation, the replacement of a fixture is no more difficult than screwing in a new lamp like you did before.

Can I realize the same savings with an LED luminaire from another manufacturer?

In short, no, you cannot.

The efficiency of the Paradin Omikron armature (up to 160 lm / W) is unmatched.

Omikron has been specifically designed from the ground up to achieve the largest possible savings. Without compromise.

Only sunlight does better.

LED technology is still in development. Isn’t it too early to switch ?

LED technology is in a similar position as the electric car. The established car manufacturers do not bring a good electric car to market because it would cannibalize their existing markets.  This has created an opportunity for new players like Tesla.

In the same way, we can not expect that manufacturers of conventional lighting bring a profitable LED fixture to market at a competitive price. Price setting is based on the existing old generation of lighting instead of actual value.

Paradin however, is not bound by the history and LED technology is already so advanced that savings of between 75% and 90% are realistic. Complex control or functions are not required.

At this time, waiting for an even higher efficiency is no longer meaningful.

Each day you wait, is a day money is lost.

Why are Paradin luminaires not dimmable?

In short, the possible savings of a dimming function does not justify its additional cost.

Connecting a controller increases the cost and significantly reduces the efficiency of the fixture.

The additional components also make the fixture more sensitive to defects.

In addition, you still have additional costs for the installation of a system that controls the dimming – unless this would be done manually, which is not a realistic option for the type of workshops, sports halls, etc .. which our lighting targets. (see also the question on daylight control).

Finally, it is so that, if your system is dimmed during a significant period of time there are quite simply too many lamps. It is more efficient to simply install fewer lamps or extinguish some of the lamps.

A lamp that is off still consumes the least.

Why do Paradin luminaires not have daylight control?

As shown in the IWT TETRA-project “Impact of daylight control systems for design and renovation of school buildings” conducted in collaboration with the University of Leuven, the savings that can be achieved with daylight control in a classroom is about 8 Euro per year.

The saving was achieved with fluorescent lighting and ignores the costs of adjustment of the system (costs which ran very high!).

Given that our LED lighting is much more economical, you can see for yourself that with a reduction of 2 euros per year, the investment in purchasing and adjustment of daylight control could never be recouped.

Why does Paradin not use lenses on its fixture?

Narrow beam lenses are especially useful if you have a specific planar work surface or a certain fixed place that needs to be lit.

However, in most workshops it is particularly important that there is light in all directions.

There are additional important drawbacks to using lenses. There is a loss of up to 20% percent in light output which translates immediately into lower efficiency. Also, the thermal management of the LED is not so good, which raises wear and tear.

Unless the lamp is enclosed the rough surface formed by the lenses will easily collect dust and dirt and make it difficult to clean.

What does 500 lux mean exactly? How can I visualize this?

The lux (symbol lx) is a unit of illuminance, measuring luminous flux on a surface per unit area. One lux equals one lumen per square meter (1 lx = 1 lm / m2).

A luminous flux of 1000 lumens, concentrated on a surface of 1 square meter, will illumate that surface with an intensity of 1,000 lux. The same source of light spread over a surface area of ​​10 square meters produces a much lower illuminance of 100 lux. Illuminating a larger surface area with the same amount of lux thus requires a light source having more lumens.

The examples below give an idea of ​​what different lux values ​​mean in practice:

• Direct Sunlight: 30000-100000 lux

• Daylight (indirect sunlight): 10000-25000 lux

• Cloudy day: 1000 lux

• Sunrise on a clear day: 400 lux

• Low light: 10 lux

• Full moon on a clear night: 0.1 – 1 lux

As you can see, direct sunlight is beyond compare.

Whit regard to artificial lighting 500 lx or more if effectively a luxury.

In order to be truly comfortable while working, between 300 lx and 500 lx is needed, especially if reading printed material is required.

Between 150 lx and 300 lx is enough to perform not too detailed work.

For passages or locations with only people traffic, 50 lx to 150 lx is sufficient.

Do the fixtures really last 50.000 hours? What does L80B50 mean?

The luminaires indeed have a projected service life of at least 50,000 hours. This means that they have been designed to be in use for at least that number of working hours before they need to be replaced.

However, this does not tell the full story. It is conceivable that during this period a number of the individual LEDs in the luminaire could malfunction or have a decreased light ouput.

The service life and quality of LEDs is therefore expressed by means of 2 indicators: the “L” en “B” parameters.

• L: shows the percentage of light output compared to a brand new fixture.

• B: specifies the “failure rate“, the percentage of LEDs that do not emit light.

The value of these two parameters is communicated for a specific service period, often this is 50,000 hours.

L80 @ B10 50,000hrs means that after 50,000 hours at least 90% of the LEDs still function and that these still emit at least 80% of their original light output.

In real circumstances this means at least 72% of the original light output after 50,000 hours, or, in case of an 8500 lumen fixture, at least 6120 lumen.

Understandably, these figures are based on estimates and accelerated wear tests. The fixtures have not yet been in production long enough to have units that have effectively already been lit for 50,000 hours.

Our own measurements at the customers that we have installed and have seen the longest use (approximately 5,000 hours) have indicated no loss of light output in real word conditions. That is to say, the same amount of lux on the working plane was measured coming from the used luminaire as from a new one at the exact position.

Finally, it is interesting for you to take into account the number of working hours per year to assess what this value effectively means to you. In case of dayshift work during the week, this equates to approximately 2200 hours per year, and therefore 50,000 hours represents a period of than 22 years of use. However, in case of full-time shift work including weekends, this same service period covers only 6 years – which means that almost the entire service life of the fixture is covered by the 5 year warranty.

Does an LED fixture give off less light with the passage of time?

The figures that manufacturers give about light loss of LEDs are based on estimates and accelerated aging tests. The newest LEDs have not been in production long enough to have items that have effectively been switched on for tens of thousands of hours. More information can be found in the question about L80B50.

Wer are convinced that al ot of these tests, figures and certificates paint only a partial picture of the real world situation on the workfloor.

Next to the possible decrease in light output of the LEDs there is a host of other factors that negatively influence the light output with the passage of time, such as decreased reflection of floor and walls in the building and dirt on the fixture.

Over a period of 15 to 20 years these factors play a very important role.

LED is in essence a very economical, reliable and environmentally friendly technology. The Paradin Omikron is protected from pollution – at least as important as internal wear and tear – thanks to simple cleaning or replacement of the (patented) extra cover only available on the Omikron fixture.

Our own measurements in the installations that we have placed ourselves and that have been in use the longest (approx. 5000 hours of continuous use) we have not been able to discover any significant loss of light output in real world circumstances. This means that the same lux value on the working plane was measured with the fixture that has been used as with a new one in exactly the same place.

How much light is needed in a workspace?

The lighting standards on the workfloor are determined by a suggestive European norm NEN-EN 12464-1.

For a normal workspace 300 lux is seen as the lower end for good lighting.

In case of detailed work or a lot of reading, 500 lux is needed.

There is, however, a clear link between the amount of light and the productivity of your employees.

More light is therefore clearly no luxury.

What is the difference between the Omikron fixture and conventional T8 or T5 lamp?

A 150cm long T8 lamp with conventional driver (CVSA) uses approximately 72W per lamp. For a T5 lamp with electronic driver (EVSA) it is at least 60W per lamp.

In professional used luminaires there are often 2 lamps per fixture.

A single Omikron Evo II lamp produces more light than both TL tubes in a conventional fixture and uses only 54W.

Additionaly, LED technology does not use any heavy metals.

Theres is also no loss of light output because LED has a much more directed beam of light. There is no need for extra mirrors or reflectors (25 € each) in the fixture.

The fixture which can be installed in one piece using a power cable is very easy to install as well as maintain.

Our standard fixture is protected against dust and water at IP65.

Not only the power use, but the entire Omikron concept is a breakthrough in professional lighting.

Hoe staat Paradin tegenover LED-Tubes als vervanging voor TL?

Paradin does not view LED-Tubes as a good replacement for TL lighting.  This is why we do not offer it to our customers.

The advantages such as in-place replacement and low costs are more than nullified by the low light output and low quality of the LED tubes.

De Omikron fixture has been designed from scratch as a complete LED fixture and can exploit all of the advantagees of the LED technlogy, without being concerned about historic backward compatibility with existing TL fixtures.

According to us LED Tubes have following disadvantages:

• The total light output is significantly lower than current TL and especially when compared to the Omikron fixture.

• Are not compliant with the norm for harmonic distortion

• Show a very bad power factor (cos(?))

• Existing fixtures are designed to hold TL lamps, not LED tubes

How much can I save when replacing my TL lighting?

Depending on the age of your installation you can save up to 80% of your eneergy usage when you switch from conventional lighting to high efficiency LED lighting. LED fixtures are not only much more (more light for less energy use), often you will need less fixtures.

The advantage is not only financially large, but also for the environment switching is a significant leap forwards, because you indirectly decrease your CO2 production.
