Greetings from Toronto

Depending on the manufacturer that could be anything from 100w to 450w out the wall.

To get an equivalent to 1000w HPS you want something around 450W + out of the wall. Don’t believe what it says on the advertisement especially if they are coming from China.

2 real 1000w equivalent LEDs will be too much light in a 4x4.

If you have some DIY skills check out this thread. Save some money and get some decent light coverage.
