I want to start to do some proper indoor growing and am very interested in LED lights, I am not too keen on the usual chinese blackstar240 and worse types and didnt want to buy from the USA if possible . I was looking for a UK manufacturer and came across GrowNorthern which does 3w and 5 w versions and a modular system too and a good price. They look good and the specs seem ok

they do a 3 year warranty and a 24 day returns policy which sounds encouraging. Any thoughts?
