Hello and welcome to GD. I just want to explain what i said about lightcompanies. They call their products.. for exaple bigstar 1000, and it just has 400 watts. and its written anywhere very small wich the true wattage is. Ive bought an 150W Ufo-Looking light for my seedlings, and the true wattage is 25 watt....but it was very cheap only 15€uros, and i use it fo my smallest plants. most chinese Led comanies do that, titeling their products with higher numbers....
happy growing
