the hilux and Sunmaster hps bulbs claim to have 90,000 lumens where as the Hortilux only has 88,000. I just want to know which brand has the best blue spectrum to maintain tight plants during flowering.

or should i just get a regular 400w MH and adjust the wattage on my ballast? Was leaning toward the 600w conversion for lumen output but was questioning the operation of it in my digital ballast.
