I just checked the efficiency rating on MY mean-well drivers. Here is the information from their website:
HLG-240H series is a 240W AC/DC LED driver featuring the dual mode constant voltage and constantcurrent output.
HLG-240H operates from 90 305VAC and offers models with different rated voltage rangingļ½between 12V and 54V. Thanks to the high efficiency up to 93.5%, with the fanless design, the entire series isable to operate for -40~ +90Ā°CĀ°Ccase temperature under free air convection. The design of metal housingand IP67/IP65 ingress protection level allows this series to fit both indoor and outdoor applications.
HLG-240His equipped with various function options, such asdimming methodologies, so as to provide the optimal designflexibility for LED lighting system.
It's stating it's efficiency rating is UP TO 93.5%. Here's where I have a problem with your statement in a previous post. You stated that your driver runs at it's highest efficiency when it's running 100%. That's usually not how electricity works. Where there is heat, there is a loss of efficiency. Your driver at 100% is going to be hotter than it is at 70%. So your driver is MORE efficient at lower wattage than it is at 100%. If you have your LED driver mounted remotely because of heat ... it's highly unlikely its running at 95% efficiency. More typical would be 85% with most switching power supplies.
If I am wrong about this, I'll eat crow AFTER seeing it from a non-biased source. I did a quick search online for 3rd party testing and didn't find it at a glance.
