lol only one week ago I asked a guy who modded an FT03 with a white flat and described the mod changes he made using “white flat”. I asked him if he changed the emitter :person_facepalming: which is how I learned what the actual white flat is. WF1 takes it to a whole new level but seems more understandable as an led given names like XPG, XHP… white flat is actually less easily identified as an emitter to a newcomer when I think about it :wink:

as a newcomer the first time I ever came across white flat/black flat I honestly thought it meant they changed the led board to a specific color (black/white) for the purposes of reflection or redirection of the light
