ewe, isibane se-PAR38 sesibane esilungileyo sikulungele ukuba ihagu ihlale ifudumele ebusika, isibane se-PAR38 esibonisa infrared senziwe ngeglasi ecinezelweyo, ngaphakathi kwiglasi yokushicilela yityhubhu ye-aluminium, eya kuthi ibonakalise uninzi lwe-ray ye-infrared ukuya kwicala elinye.

Ngenxa yokuba iglasi ecinezelweyo ingagcina obona bushushu bukhulu, ubushushu abukhanyiswanga ngokulula, ke amandla aphezulu ePAR38 isibane esibonisa infrared yi-175W. Nangona kunjalo, isibane se-PAR38 sesibane sokugcina umbane songa amandla ngakumbi kunesibane se-infrared reflector esenziwe ngeglasi eqinileyo.
