How will live event professionals’ benefit from improvements to the Purelight Series?
“We redesigned the whole concept, including the internal optical design and the scanning systems, to sculpt a product series with different power levels for different use scenarios. The Laserworld Purelight Series IP65 is available as 5W, 10W, 20W, 30W and now with up to 70W overall power. This covers the requirements for high precision and suitability for graphics projections and mappings with the 5W and 10W systems and caters for the demand for high power festival grade lasers with 30W, which is the somewhat standard range now. The 70W which is the range seen more at top-of-the-range festivals and productions. The balance between scanning performance and low divergence for the high power units, make the Laserworld Purelight systems proper workhorses.”
Did you face any challenges bringing this range to market?
“The main challenge with lasers is to achieve a good divergence, because that is what maintains visibility over longer distances, and at the same time have a good scanning performance. Physically, the challenge is that you can use lens systems to make the divergence, the widening of the beam over distance, smaller, but then you increase the initial beam diameter. With increased beam diameter bigger scanner mirrors for deflecting the beam and creating the ‘image’ are required, which reduced the scanning performance due to inertia. With the Laserworld Purelight Series, we managed to achieve as good as a beam performance possible as well as great scanning capabilities at the same time.”
What innovations allowed you to reduce production costs so effectively?
“Due to the large quantity of laser systems we sell, we can source very efficiently. We managed to get the most difficult part inside a high power laser system to be manufactured with optimised components and more efficiently. The laser modules are difficult to build the higher the power of the laser system, because it requires combining single laser diodes with limited maximum power to one big module, outputting only one beam, which should be as thin as possible – and this is where it becomes challenging. We found a very efficient way for doing this in our Laserworld Purelight Series systems.”
How does the range perform when it comes to power efficiency and energy use?
“The overall power consumption of a Laserworld Purelight laser system is rather low compared to other devices on stage. The Laserworld PL-30.000RGB IP65, as an example, only consumes about 900W in its maximum peak – but mostly ranges at around 200-300W.”
Can the Purelight Series withstand the rigours of the road?
“The durable metal housing provides proper protection, and the general design makes the devices easy to mount and to handle on site. It comes in a durable plastic flightcase, too, which eases the handling on the road and provides protection during transport.”
Which control standards does the Purelight Series support?
“Purelight laser systems are equipped with the powerful and versatile ShowNET laser mainboard, which supports various direct software control, but it also has a powerful DMX / Art-Net control feature built-in which allows for directly controlling the laser like a moving head without the need of any software at all – it even allows for setting the projection area and safe zones just with the lighting desk and safely storing the settings back to the main board – just with DMX / Art-Net. Of course, the standard ILDA control is still possible, so you could hook up any external controller, like a Lasergraph DSP as an example. The Purelight Series units can also be equipped with an FB4 as an alternative mainboard, if required.”
What has the response been so far from touring professionals and production teams?
“The feedback is great! We just saw the huge UNTOLD festival in Romania beginning of August with 450,000 visitors being fully equipped with Laserworld Purelight systems on all main stages by our customer KLS Lasers – and many more big festivals and productions worldwide rely on the Laserworld Purelight Series systems.”
