Violet Blue Line Projectors can be used as the light source of laser swamp. The violet laser projectors are usually used with green lasers together to set up a laser swamp with fog machines. The violet laser is not very visible to human eyes. Normally we don't use violet laser alone to build laser swamp. The violet lights are usually used as a supplementary light source to green ones to make laser swamp of different colors.With violet lasers, the swamp is more different with green ones and seems more horrible. If you want to build larger laser swamp and avoid shadows, you may need lasers to shine towards each other.

Note:
The modules are tested and the output power are measured by laser power meter before sending out.
Please don't compare the power of this one with a none-measured laser.
If you doubt the output, please have the laser you received checked by laser power meter.
If there is any problem, please feel free to contact us. We will solve the problem asap.
