And those lumens can't be multiplied, which means the plants are getting 3400 lumens, the more you add the larger an area that gets the same 3400. But that's fine if you just want to get a small grow. Are the personal growing laws in Holland still loose, or is it getting tighter?my bulbs put out 3400 lumens each
if you still have the package of the lights im sure it will say what kind they arethere just some regular bulbs from meijer and lowels i dont know what kind of spectrum they are
