now u said bout 10k lumens....so would that b total, like if u had a bulb that put out 2500L, u should use 4 which would = 10k? or jus a bulb that put out that much? i have 2 bulbs that put out i believe 3k lumens each, for a total of 6K lumens, so i should maybe get 1-2 more? or??? thnx in advance
