My lumens meter has not arrived yet. I believe it will take another one or two weeks ...
usually takes a month for imports to arrive. sometimes a little more ... yes, it's a long time and I need to have a big bag of patience.
I bought that very common model from dr. meter
I still do not know if I'm going to build that pvc pipe structure or a big styrofoam sphere. maybe both, since these materials are cheap
It will be cool to build this.
I do not intend to perform tests as advanced as yours because it would be like reinventing the wheel, but I want to have equipment to measure the lumens.
How did you build your structure? Did you use pipes too?
Thank you again for your efforts. the new way of displaying the results in the chart was very good.
