MarsHydro/TopLED growers have the same thing. Some of it has to do with how almost any light will veg great looking plants. Some has to do with lack of details about how many watts are run. (I.e., if they're running at 50w/sq ft this will make up for the inefficiencies of epi-whatever diodes.).There are a bunch of journals showing great looking plants under pled lamps...
I just got great results from 22w/sq ft of Cree lightbulbs sold at Home Depot with 10 year warranty. Doesn't mean the PLED and MarsHydro guys don't have nice looking plants. But, why spend a lot of money on epi-whatever LEDs and the electricity to power them hotter?
Also, if PlatinumLED's lights are so good, why do they have to stoop to the level of stealing AdvancedLED's name to get customers? (That alone should warn anyone away from Platinum. Why support a business that conducts itself that way? It's contrary to the 420 spirit.).
