Turboguy327, We've had our disagreements in the past, but on this I agree 100%.They aren’t actually 4000 lumen, just a heads up. The ones you have I very much doubt they are 2500 either. Offshore LED bulb swaps are incredibly inflated.
Most of the assembly companies use RAW data from the LED chip maker and real world output is usually around 85% of that.
There do seem to be a few exceptions that list more realistic numbers.
