    At the moment the good LED are mega money I was shocked how many crap products were available when i researched them fully It seems 75% of them are more a gimmick to catch people out than actual real lights

    They are still in the prototype phase in my eyes as far as horticulture is concerned, but yeah give it a few years and I reckon they will be on to a winner...

    why did you buy the unit if you think HPS outperforms it?

    Also I'm having some trouble finding proper side by sided. I would think that the LED sellers would sponsor side by side grows if they are that much better watt for watt.

    The unit I bought was designed to replace a 250w HPS. The first grow I did with it was disappointing but it was the second grow that was most telling... the veg ability of the light was truly awful

    Welcome to the forum

    I recommend choosing the light your are most comfortable with and getting to be the best grower you can be and then decide if you want to make your grow more efficient.

    Grams per watt is subjective to each grow. It's a post mortem of how well you selected genetics, environment, nutrition and lighting. I'd say lighting is the least significant here
