The reason Red, Blue and Purple/Ultraviolet lasers are not as visible as Green! Planning your BlissLights Spright Landscape laser display

USE GREEN LASERS FOR DISPLAY FIRST THEN ADD BLUE, RED OR PURPLE FOR ACCENT with extreme care –
Here is the reason Red, Blue and Purple/Ultraviolet/Blacklight lasers are not as visible as Green. Notice how Green, which is 532 nanometers (nm), is right in the middle of our visible spectrum of light. Blue is 445 nm approaching ultraviolet or “blacklight” and red is 660 nm approaching infrared which are not visible to our eyes. As a matter of fact, the RED & BLUE lasers we sell are more powerful than the green but they are still less visible because our eyes don’t receive that wavelength as well. 

PROJECT LASERS ONTO WHITE OR LIGHTER COLORED SURFACES WHENEVER POSSIBLE –
Realize that the light that our eyes see is the light that bounces off of surfaces back into our eyes. Like a movie screen, the most saturated colors come from projecting onto a bright white surface. When you shine your BlissLights Spright landscape laser into your yard, keep in mind that the white shed, birch tree bark, concrete pathways and lighter shade leaves will all show more lasers beams and brighter colors than the dark green leaves. When you are planning your Spright Landscape Laser Starfield Lighting array keep this in mind.

Here is a beautiful comparison of the BlissLights Spright in Blue, Green and Red lasers at 10′ from a surface. This clearly demonstrates why we recommend using Green first and foremost in your displays. Use the Red & Blue lasers in dark settings at closer distances and projecting onto light colored surfaces, for the maximum effect.

WHY DON’T YOU MAKE A WHITE LASER? – We also get many requests for a white laser product and must point out that lasers are nothing like light bulbs, where they originate as white and a lens is placed over them to create different colors. A white laser is a combination of all of the other colors so it would take a red, green and blue laser to create a white laser. They do exist but they are extremely expensive and complex. You can see how white light going into a prism breaks it down into all the colors of the rainbow in this photo. Imagine reversing that process where you condense the primary colors, red, green and blue, to get white light.
