Eurolite LED IP Strips

The Eurolite LED IP Strip is a self adhesive LED strip, which offers an easy installation because of its high adhesive strength. The complete LED strip set is composed of a remote control in credit card format, a control unit, a power supply unit with 36 W and of course the strip with a length of 1.5 meters. Due to the plug-type system, there is no need for soldering, the installation is very easy. The flat, dimmable LED strips can be cut every 10 cm – this offers a huge variability of use. A series connection is made possible by the connector, which comes with the device. The power supply unit supplies up to 7 LED strips.

The complete LED strip set is almost perfect for indirect lighting, especially for fair or shop applications, to create a comfortable atmosphere – warm colors, for example, can have a calming effect on the ambiance. The LED strip scores with a high intensity of brightness and colors. It is equipped with 45 RGB LEDs. All the connection pieces are of a professional quality.

You can choose between an automatic color change and the manual color and program selection with the remote control. Built-in programs offer color change, color fade and strobe effects. It’s a plus that the speed of the programs and the brightness are individually adjustable. It should also be mentioned, that 16 colors can be picked directly and that there is a memory function.

The LED strip can be mounted inside as well as outside (IP 68), it has a silicone sleeving, which protects the damageable LEDs against water.

The control unit of the LED set is compact, it can be built in, and it has connections for the power supply unit, the remote infrared sensor and the LED strip.

The functionality and the quality of this products leaves nothing to be desired.

You don’t need DMX to control a KLS an four additional spots – you only need a DMX line…

EUROLITE FP-1A DMX line, a spot with 3 DMX channels and the Eurolite FP-1 foot pedal, to be more precise. Sound strange, but it is not at all. A maximum of four spot have to be connected to the DMX out of the KLS and then lopped through (it works with KLS- 200, 401, 801, 1001). Everything is controlled with the foot pedal in a kind of Master/Slave mode.

Necessary requirement, the spot’s 3 channel DMX mode needs the following starting addresses:

Synchronic to panel 1 of the respective KLS: starting address 4
Synchronic to panel 2 of the respective KLS: starting address 7
Synchronic to panel 3 of the respective KLS: starting address 10
Synchronic to panel 4 of the respective KLS: starting address 13

EUROLITE KLS

Functionality of the foot switch remains unchanged: blackout, freeze, sound control, auto program.

Here are some of our spots which can be connected:
EUROLITE ACS Bars RGB,
EUROLITE PAR-64 RGB 24x5W,
EUROLITE PAR-64 RGB 36x1W Short sil
EUROLITE ML-56 TCL 18x3W
EUROLITE PAR-64 TCL 18x3W

To those who cannot call a KLS their own we recommend to take a look at our 8 KLS Kombo Packs. With the Kombo Pack 7 we also offer an alternative without DMX.

Scanner with LED or halogen?

Scanner Halogen LED

Scanners also offer the choice. The choice between conventional or new technology: halogen or LED. We show you, which devices are comparable. The final decision, which way to go in the future is not ours, it is up to you…

Compared to static effects scanners feature a benefit. Due to the mirror deflaction the light beams have wider operating range. Moreover, the show gets more dynamic with the motion of the mirrors. But how to create this dynamic action, with halogen or LED? After all, it is a given fact, that considering the light power. LEDs have closed the ranks a can replace halogen models easily. We show you which models can be compared and thus are exchangeable.

With conventional lightbulbs it has begun – electric light for everybody. Read about the history of modern light…

Within the past five to ten years, LEDs became very popular in the lighting industry. With all the hype about even brighter LEDs one might forget that there are still conventional lightbulbs.

Sometimes one feels reminded of the “wars” between analog and digital signal processing in audio technology when incandescent lamps are called “warm” and LEDs are called “cold”. On the other hand, the lightbulb’s light efficiency of 5 to 30 lumens per watts or an efficiency of less than 10 % is considered to be very low and not environmentally friendly. This is why the lightbulb is partly forbidden in Australia and in the EU – a development which did not help the LED but the energy-saving lamp which is also not environmentally friendly.

For the entertainment industry, the wide selection of different lamps is very positive. Technicians can choose from a large variety of tools to be used for solving a lighting installation. When classical incandescent lamps should be used, one must make a decision between with halogen additive or not. Halogen lamps have a longer live and are a little brighter at the same wattage. Are there any other differences? Which are the main steps in the development of incandescent lamps?

GlühlampeThe lightbulb’s history dates back more than 200 years. In 1802, the Englishman Sir Humphry Davy experimented with the just invented battery and platinum filaments, but nowadays he is more known for developing the carbon-filament bulb. For the early 19th century, there is also controversial evidence for a lightbulb designed by De la Rue or De la Rive. Up to now, neither the designer, nor the origin or an exact year could be given. The sources speak of an invention around 1820 or even earlier, however, there is no evidence from this period of time. In 1835, the Scottish James Bowman Lindsay publicly presented a lightbulb with platinum filament and vacuum flask, but he didn’t continue to pursue the idea. Further patents of other scientists followed in the 1840s and the 1850s. A mass production never started because platinum has a melting point of approx. 1770° C and the light efficiency was rather low. High material costs also contributed to the failure.

Thomas_Alva_Edison_kToday, Thomas Alva Edison is regarded as the real inventor of the incandescent lamp as he succeeded around 1880 with carbonized bamboo filaments. With the coal he could work with the double temperature compared with platinum. Edison already had some experience with the coal filament from earlier inventions. The legend that the German Heinrich Göbel already invented a working coal filament bulb in 1854 cannot be maintained when regarding the sources and was maybe only announced due to patent litigations with Edison.

Patent Light_bulb_EdisonThe coal filament was quickly replaced by materials like osmium and tantalum which were first available at the turn of the century. The material tungsten with a melting point of 3400° C, which is still being used today, was only available a little later due to the contributions of Carl Auer von Welsbach, the founder of OSRAM, and other scientists. But again, it was Edisons company General Electric (GE) which launched the lightbulb as known today from 1911. GE’s success remains until today because most household lamps still use the base with Edison thread (E14, E27, E40). Further improvements were reached by adding noble gas and spiral heating coils.

The lightbulb’s life is limited because atoms leave the heating coil at especially hot places. These atoms gather at the cooler flask. When a larger flask is used, the gathering can be spread on a larger space and the shadowing of the glass can be reduced a little bit. The number of atoms leaving from the heating coil depends very much from the voltage being used and thus the temperature being reached. Increasing the voltage by 20 % doubles the brightness, but also reduces the life by 95 %. Increasing the voltage by only 5 % still reduces the life by 50 %. In the first half of the 20th century, finding the compromise between brightness or light efficiency and the lamp life lead to an illegal cartel with all big manufacturers like General Electric, Osram and Philips. Still today, there are rumors that manufacturers artificially reduce the lamp life.

By adding noble gas like xenon, argon or krypton, the evaporation of heating coil tungsten atoms can be reduced. Furthermore, the noble gas allows a higher heating coil temperature and thus a higher light efficiency. This can be optimized by increasing the interior pressure of the flask, but the maximum interior pressure depends on the ruggedness of the flask.

In the middle of the 20th century, the development of halogen lamps brought several essential improvements. Additional halogen like iodine reacts with the vaporizing tungsten and stabilizes a tungsten containing atmosphere in the flask. The tungsten condensate does not gather on the glass but again on the heating coil. As the tungsten moves rather to the thicker parts of the heating coil, the lamp life is not significantly increased. Instead, the halogen enables much more compact flasks so that even higher interior pressure can be realized. Furthermore, a smaller flask reduces the costs for filling it with expensive noble gas. The decisive point for a longer lamp life of halogen lamps is not the tungsten-halogen-circle, but the especially high interior pressure of the gas. A further contribution was the invention of especially rugged and heat-resistant silica glass.

Some day, the heating coil of a halogen lamp does also burn through because noble gas and halogen cannot avoid that the heating coil becomes thinner at some places and finally burns through. Mostly, this happens in a critical situation when switching on and when a very high currents runs through the lamp. We refer to the pre-heat-function of many dimmers and lighting controllers which provide voltage to the lamp shortly below lighting up and thus reducing the starting currents.

Another advantage of halogen lamps is the much higher light efficiency especially in the low voltage sector. Halogen lamps can be operated at low voltage in households.

Why should any technician choose lightbulbs without halogen mixing, when there are so many advantages?

Next to the price difference between the two versions, the light temperature and its spectrum is also very important. Even carbon-filament bulbs are still popular as they have their own specifications regarding color temperature and starting behavior. Halogen lamps have a color temperature of 3000 and 3400 Kelvin, “normal” bulbs have 2200 to 2800 Kelvin depending on the wattage and the filling.

In artistically demanding surroundings, it may be useful to have bulbs without halogen mixture. Halogen lamps also have the disadvantage that they emit a low portion of ultraviolet light so that skin burns may be caused or color surfaces may be bleached.

EUROLITE LED SLS Series

November 22nd, 2011 Posted in EUROLITE Tags: , , , , ,

Eurolite SLS

It’s the popular KLS which has paved the path for Slim Line Spots. The KLS has been the first successful attempt to replace bulky PAR spots by compact and flat ones – on a bar with 4 spots abreast. As is well known, the concept has been a raving success. As a logic consequence we also transformed the form of single spots – the SLS were born.

Obvious advantages of the SLS: they are slim. Compared to common PAR spots they considerably save space. For this reason they are much more flexible and handy. This is also true for installation, stock ground and transport – for most SLS we sell special cases which are smaller and cheaper than those for PAR spots. In the end, the design can save money.

Meanwhile Eurolite has build up a very rich assortment full of different spots. An assortment which is continuously enlarged. Every delivery finally includes a double bracket enabling an additional use as floor spot. Beside the different sizes of the spots the main differences can be seen in the illuminants. A choice of single LEDs, bicolor, tricolor and quadcolor LEDs is offered.
You can compare the spots in the list below. Read more »
