ES330 LED Grow Light

I purchased a similar light from one of LumiGrow's vendors that became defective (lights began blinking on and off sporadically) within a month of the purchase. The vendor said that it was under warranty (5 years) with LumiGrow and to contact them. I did. LumiGrow said that they would not send me a new one. They (Tammy, who was also very rude) wanted me to send the old one in and for me to wait a month or two until they repaired it. I have a garden full of food growing under this light in my greenhouse that I can't abandon (especially in the winter). This is some of the worst customer service experiences I've ever had. Luckily the vendor went ahead and sent me a new light and worked it out with LumiGrow themselves. LumiGrow is horrible! I will never buy another LumiGrow product.
