About this product

JBLED A7

With the JBLED A7, JB-lighting presents the next generation of moving head with LED assembly and the successful successor of the VaryLED 3 * 84.

The JBLED A7 is equipped with 108 Luxeon high-power LEDs which have been placed at exceptionally narrow distances from one another, thus enabling uniform color mixing. With the selection and number of LEDs used, the maximum color space can be displayed. The JBLED A7 benefits from new manufacturing techniques for blue and green LEDs.
Compared to its predecessor, the light output increased by 40% at blue and nearly 100% at green. Due to this development the JBLED A7 is not only the brightest device in its class, the light output at white (mixed of red, green and blue) has even doubled.
JB-lighting achieved a great success with the further development of the optical system. Since the optics currently available on the market are not suitable for the development of a zoom system, a new, highly efficient lens system has been developed. The emission characteristics of the spotlight show a clearly defined light cone, which is comparable to a conventional washlight and no longer shows the wide diffuse scattered light field of earlier devices.
The zoom range of the JBLED A7 features remarkable 8 ° -36 ° (8 ° -28 ° 1/2 peak, 12 -36 ° 1/10 peak)!
The JBLED A7 will be available in four different versions. As a stage effect light, the headlights come with a standard set of red, green and blue LEDs. Furthermore, a device with pure white LEDs in cold white color temperature is offered for trade fair and front light applications. The JBLED A7 can be used universally with two thirds cold white and one third amber colored LEDs. The product range is rounded off by a JBLED A7, which is exclusively equipped with warm white LEDs and is suitable as a front light for stages and theaters.
In addition to the familiar advantages of the LEDs, which are all found in the JBLED A7, such as low current consumption, low weight and low heat emission, the concept of the headlamp has been designed to be extremely quiet. This makes him ideal for theater and TV applications.

Used JB-Lighting

JB-Lighting develops, designs and produces for 25 years and intelligent lighting Light controllers exclusively on location Blaustein in southern Germany,historical It all began with the fascination that mirror scanners have applied to the company founder Jürgen Braungardt.
The then-new technique that combined complex mechanics and analog (later digital) control, Jürgen Braungardt inspired them to develop their own spotlight.
While to 1999 mainly scanners and color changers manufactured and sold under the brand name Varyscan and Varycolor, made ​​JB-lighting from 2000, moving lights and introduced a new mixer series under the name Licon ago.
The focus was -damals like today - it always to develop reliable and user-friendly products.So it is not surprising that even today there are still many lights in use, which have left the factory many years ago to be used in discotheques, clubs, bars or on live stages.Pioneering work opened a new chapter in lighting technology JB- Lighting in 2005 and presented the VaryLED 3 * 84 the first stage-ready LED-based wash light that brought together all the benefits of LED technology like flat design, low energy consumption and long service life.Thus, JB-lighting was an outstanding pioneer of a marketplace, the focus is almost all major manufacturers now.
2008 followed with the A7 JBLED the first LED-based wash light that has an optical zoom system.The product won the Plasa Award for Innovation awarded and the jury praised the JBLED A7 rightly considered the founder of a new era.

Cyclorama Light (Cyc Light): A light source mounted at the top or bottom of a cyclorama in order to light it in a smooth, uniform manner. Daisy Chain: A control signal wiring system employed in the interconnection of a plurality of some electronic items, such that the first item’s output connector is connected to a second item’s input connector via a control cable. A third item is connected to the second in the same manner, and so on until all items have been connected. The control console is connected to the input connector of the first item only, but sends data to all items via the interconnecting control cables. Some items that can sometimes be daisy chained are color scrollers, automated light sources and dimmer racks or packs. See Feed Through.
