Ok poorly made drivers makes more sense than Chinese ones. I also understand what you mean from changing the bulbs after they start to loose colour for looks and for growing reasons, I guess it boils down to each person needs for what they want to grow and how often you want to do the upkeep.
Im wondering now that you mentioned the lower power leds if you cant just use more of them instead of the higher intensity ones? So instead of 1W leds you grab 2 smaller ones or 4 depending on the amperage they are and use those instead? Again it might depend on the tank you want to put them over..
