How much unwanted visible light does the LG output compared to the nichia? and in terms of UV output is the LG better. You said it’s a not a huge difference but it’s noticeably brighter. Does that mean the light physically is almost the same but the performance is much better? Could you post a pic of both if you still have them? According to djozz tests the filter should block out all the light so the LG makes more sense I guess.
