Boulderlamp MoonWalker LED Grow Light is Good for Plants but Bad for Bugs and Germs

Boulderlamp MoonWalker LED grow light is good for plants but bad for bugs and germs


More yields with less energy, keeps bugs away, and kills germs meaning a healthy and clean environment for plants and workers tending the plants.


Patented technology, MoonWalker SB1 cycling beam is made of 405 nm purple, 395 nm UVA, and full-spectrum white light. Unlike UVB and UVC, 405 nm and 395 nm lights are safe for human exposure.


MoonWalker SB1 can deliver a combined LED power of up to 920W. The LED power for the cycling beam portion is 200W. At about 1 foot above canopy the light level is up to 2,000 PPFD (µMol/m2/S).


MoonWalker cycling beam is very intense and cycles between light bars or fixtures periodically and since this beam is not stationary, full sun-like intensity does not burn or harm the top of the canopy while reaching middle, bottom, and side of canopy with sufficiently high intensity resulting, a) increased photosynthesis activities meaning more crop yield, and b) the antimicrobial component of the light beam continuously disinfecting the air and grow room surfaces, and creating a hostile environment for spider mite, molds, E. coli, and other bugs and pathogens within the canopy.


The following are only a few examples but these research papers and journal articles sufficiently validates antimicrobial properties of 405nm and its applications:

(*1) “405-nm LED treatment could be used to effectively prevent and/or control with L. monocytogenes contamination along the entire food-processing chain, from production to consumption”. This was published in Frontier of Microbiology in August 2019.

(*2) LEDs Magazine, May 2021,“Antimicrobial visible LED light is confirmed to deactivate viruses including SARS-CoV-2 Multiple laboratory trials have documented that violet radiation around 405 nm can over time deactivate viruses, including the coronavirus that caused the COVID-19 pandemic”.
