yup... which is why my friend said no go for the application i want.
I would get the other spectrum which arent needed inside the lux, and wouldnt represent anything.. minus how well the camera would take its picture at what flash setting

Ohhhh if u figure out a way hoppy let me know..
My friend whose a professional photographer said he would totally loan me his lux meter. But as i said, he said it was pointless for what i wanted.
He knows what a par meter is, and said get a cheap par meter.

Problem tho, a Par meter costs 200 dollars!!!
I still want my dual stage regulator b4 a Par meter.
