What are the important factors when choosing Concert Laser Lights?
1. Brightness and Power
✦Brightness
Brightness is a key indicator that determines the visibility of laser lights in the performance environment. For large concerts or outdoor performances, higher brightness laser lights are required to ensure that the laser effects are still clearly visible at a longer distance and in strong ambient light. Generally speaking, brightness is measured in lumens. Higher lumen values mean brighter light. For example, in a large stadium performance, a laser light with a brightness of thousands of lumens may be required to allow the audience sitting in the distant audience seats to clearly see the laser effects.
✦Power
Power is closely related to brightness, and generally the higher the power, the higher the brightness. The power of laser lights is measured in watts (W). However, it should be noted that high-power laser lights may pose safety risks, such as damage to human eyes. For small indoor concerts, laser lights with a power of between 1 and 5 watts may be sufficient; for large outdoor performances, laser lights with a power of more than 10 watts may be required. At the same time, in many countries and regions, there are strict safety regulations and licensing requirements for the use of high-power laser equipment.
2. Color and color effects
Laser lights can only provide three colors: red, green, and blue. These three colors can produce a variety of color effects by mixing; good color mixing is very pure, can accurately mix colors, can maximize overlap, and produce smooth and uniform color transitions. For example, in a concert with the theme of "Fantasy Wonderland", laser lights that can produce soft light blue and lavender gradient effects can create a very romantic atmosphere.
3. Beam quality and pattern effects
✦Beam quality
A high-quality beam should be clear and sharp. Check the beam divergence angle of the laser light. A smaller divergence angle means that the beam can travel a longer distance without excessive diffusion. For example, on a large stage, if the beam divergence angle is too large, when the laser shines to the back of the stage, the beam will become very wide and lose its original focusing effect. Generally speaking, the beam divergence angle of laser lights used for performances is preferably between 1 and 5 milliradians (mrad).
✦Pattern Effects
Laser lights can produce a variety of patterns, such as dots, lines, geometric shapes (such as circles, squares), complex patterns, etc. Choosing laser lights with rich pattern effects can add more creativity to the performance. Some laser lights also support custom pattern functions, and users can create unique patterns through software or built-in pattern editors. For example, in a performance with a sense of technology, laser lights that can project circuit board patterns or sci-fi style symbols can fit the theme well.
4. Scanning speed and motion effects
✦Scanning speed
The scanning speed determines how quickly the laser light can change the direction and position of the beam. For fast-paced music performances, a higher scanning speed is required to keep up with the rhythm of the music and create dynamic and lively visual effects. Scanning speed is usually measured in degrees/second (°/s). For example, some laser lights used for electronic music performances can scan at speeds of more than 40,000°/s, which can quickly switch the beam position between the stage and the audience area.
✦Motion effects
Consider the movement mode of the laser light, such as shaking head, swinging, etc. Laser lights with multiple motion modes can cover the performance space more flexibly. Some laser lights can also be programmed to achieve complex motion trajectories, such as spirals and waves, to create unique spatial visual effects for the performance. For example, in a dance performance, the beam of the laser light can move according to the dancer's motion trajectory, enhancing the interactivity and viewing of the performance.
5. Control method
Control method
There are many ways to control laser lights, including manual control, DMX control and software control.
Manual control is suitable for simple operation scenarios. Users can adjust parameters such as brightness and color through knobs and buttons on the lamps. Such operations are not used in concerts.DMX control is the most commonly used standard control method in the performance industry. It allows unified and precise control of multiple laser lights through the DMX console to achieve complex light show choreography.Software control provides more advanced functions, such as graphical programming, scene presets and real-time effect adjustment through various laser software. This control scheme is the most commonly used in concerts.
