Looking at the signalight led anchor light I see fins on the bottom of 
the unit. Those prob. are NOT needed due to heat from the led, but 
rather heat from  the circuit powering the led, a sign that it is not 
very efficient.
They look sharp but what is inside that  nice package as far as 
electrical efficiency? OGM uses a very efficient design, I know that for 
a fact. Others are even more efficient.

Does it matter? Yes.  With an inefficient light you need a larger solar 
panel and more batteries, and/or may only have a week or  two to three 
of  operation before you MUST charge the batteries, with an efficient 
design you may have several months.
A few dollars more for a light that is more efficient can save hundreds 
of dollars in equipment cost to make up for poor performance.
And if you find yourself without any way to make electric power or store 
much of it during a passage, having lights that are tops in efficiency 
can literally be a lifesaver. -Ken
