Simba rechiedza rinobva kune chero mudziyo we LED kana laser therapy rinogona kuyedzwa ne 'solar power meter' - chigadzirwa chinowanzo nzwa chiedza chiri pakati pe400nm - 1100nm - zvichipa kuverenga mu mW/cm² kana W/m² (100W/m² = 10mW/cm²).
Uchishandisa chiyereso chemagetsi ezuva nerura, unogona kuyera huwandu hwesimba rechiedza chako nedaro.
Unogona kuyedza chero LED kana laser kuti uone huwandu hwesimba pane imwe nzvimbo. Mwenje yakazara yakaita seincandescents & heat lamps haigoni kuyedzwa nenzira iyi zvinosuwisa kuti yakawanda yemagetsi haikodzeri kurapwa nechiedza, saka kuverenga kwacho kuchawedzera simba. MaLaser nemaLED anopa kuverenga kwakarurama nekuti anongoburitsa wavelengths +/-20 yewavelength yavo yakatarwa. 'Solar' power metres zviri pachena kuti yakagadzirirwa kuyera chiedza chezuva, saka haina kuenzaniswa zvakakwana kuti iongorore wavelength imwe chete yechiedza che LED - kuverenga kwacho kuchave kwakaringana asi kwakaringana. Kune ma LED light metres akarurama (uye anodhura).
