The FIREFLY Spider can control up to 100 FIREFLY 1000W HPS (Pro) fixtures. By connecting your FIREFLY fixtures to the Spider, you can dim the lights with 1% increments, turn them all on/off at once, program a timer to turn them on/off, including with a sunset/sunrise feature, connect up to 2 sensors (included in the box) that measure temperature and humidity, and set min/max safety values for these criteria so that the Spider will switch off all lights if they are too high.
