Led light and intensity meter suggestions

Hi guys, I'm just looking for a couple ideas for measuring the light my plants are getting at the canopy level I'm running a dwc setup with 6 plants in a 5x5 tent and I have a kind k5 xl 1000 led light i have this thing 30 inches from my canopy and at 75% power they'll start burning the leaves. I'm a perfectionist so I'd like to be able to dial in the amount of blue spectrum and red spectrum for optimal growth and measure the uvb output if possible so if anyone out there has any experience measuring LED light output I'd like to hear your thoughts and product suggestions. Again I'd like to hear from people who have experienced first hand please and accurately measure led not mh or hps there's different meters for different light sources I've been reading.
