Being a shop that prides ourselves on giving our customers what their money pays for, we were surprised by the vast differences of output between ballasts and not just chinese imports.
Having tested the output in lumens and wattage I was very surprised by the outcome.
We pay for ballast that says 600W so we want 600W not 500W, so we set up a display to show this in one of our grow rooms to highlight this to our customers. The difference between the wattage and light output is costing you money, so demand a ballast that offers this, we found Maxibright compact ballasts offer the best value for money and give you what you pay for.
