Lets be real. There are tons of lights on the market, but one thing definitely remains true; black box leds cost WAY less than the so called "real" reef lights toted by big name aquarium companies. I'm talking price gaps of $500 to $1000 different when you include the $100+ mounting arms (that are free in black box set ups btw... I mean really? $100 for a $8 metal arm at cost? In addition to the huge cost of the light?) Its clear why i think a lot of people would choose black boxes over big name lights. So I really want to know, what makes a $1000 light so much better? The simple fact that the mounting arm is an overpriced add on makes me believe its more of a money grab scheme than anything else. So, this is a real question, I really want to know what makes them worth the 5x - 10x extra cost.
