I know some people like them but I'm going to say the marine orbit, rather pricy light but the timer kept failing and LED's started burning out after 2 years. Eventually threw it out when the inside of it rusted right out. To the point I could actually see rust around the LEDs. I also find I have better growth with just about any other light including black box leds.
