You make a very valid point there, might as well spend a few extra bucks and have the best.$69 hortilux bulbs are still the best deal posted so far. Do people seriously use those $30 bulbs on their plants? All that money for seeds, nutes, amendments, equipment, ELECTRICITY, and you use cheap lights? No comprendo...
