Attaching a homemade LED light to the back of a jar.
I have half gallon and gallon jars with plants in them. I'd like to attach a light source to it. Maybe not directly up against the back of the glass, maybe an in pr
two away so that the light and jar are more or less one thing.
Since it's a small space and the light would be so close does anyone know what strength of LED would most closely equal medium light?
