Well lumens can be increased by just adding more of them, I think they tend to be in the blue spec, but they are closer to 6500k9Daylight) than anyother lights, that I know of. If there is not someting inherantly wrong with the type of light a led produces then everything elest could be caculated out to specifications for the size of the room, also I'll say again heat from the bulbs would be very very low only 1-5% of typical bulbs. I'm just asking and don't know that whay I posted I know a true green tumb can tell use yes if its BRIGHT enough then they would be good.
