These lights can be used for seedlings and early veg, but will not do you justice for an entire grow. You can probably get creative and use them as supplemental lighting during flowering, but a new, more powerful light (preferably full spectrum with IR and UV) will be needed as a main light for flowering.
Be careful when choosing a light. Too many off-brand LED manufacturers advertise their "HID equivalent" wattage and not their actual power usage. You can usually divide this number by about 4 to get actual power usage, but doing the volts x amps or reading fine print will get the actual power draw.
Off-brand doesn't mean bad though. I have been using some Roleadro lights for 6 years. I just know that when they say 600w they actually mean 140w and are only good for about 2x2 areas (35w/sqft). To me, paying $50 per light for 6 years of use and counting is a great deal. I could have bought name brand for 4+ times the price, but I don't see them lasting 4+ times longer.
