Didn't work for me after multiple attempts
This is a super expensive light meter that I was encouraged to buy for an indoor plant class. Not only was it not worth the high price, but I still can't get it to read DLI after referring to the manual, the YouTube video, and asking my professor for help. It has TWO BUTTONS. It should NOT BE HARD TO USE. I contacted the manufacturer who just resent me the manual I already can download from Amazon. I do not recommend this and will attempting to return (I threw away the box) or give to a classmate. A huge waste of money and effort.
