If your LEDs are powered by low voltage DC and they are low intensity then they are probably very efficient.
The main inefficiencies for LEDs come from the power supply turning high voltage AC to low voltage DC and trying to get too much light from too small a package. LED efficiency is limited by quantum physics once you start passing more than 10ma per diode junction.
I started that post because I was told I should replace my T5 florescent light fixtures that I got for free with "more efficient LEDs".
