This is a very solidly built industrial quality device. There are any number of "cheapies" on eBay and similar that offer a 1,000 Watts for less than $100. They don't - when you look at their power consumption, it might only be 100W. That is supposedly equivalent to 1,000 W of incadescent bulbs. This unit really does pump out a full 300W of high efficiency LED light as advertised - extremely bright. Great little unit.
