Watch this video to see the dramatic contrast in brightness in laser beams and all lighting depending on the darkness of the surface or "screen" being projected on to. Here is a brief demonstration of the variation in brightness of a green laser beam from a BlissLights Bliss 50 as it passes from a white wall to a dark brown door. You can find these Laser and LED projectors for inside and outside displays on our website at www.LasersandLights.com. Consider this dramatic difference when planning lighting displays and favor white or light surfaces. For even more dramatic bright lighting add a fine water haze or layers of thin white veil fabrics to bring out the 3D effects inherent in these holographic projections. You will find this and many other transformative projectors at our website www.LasersandLights.com for homes, parties, dance events, festivals, meditation studios, gardens, weddings and more.
