Here's a question about my Whelen strobe power supply that nobody I 
ask seems to know the answer to.

I have the three-light unit that Lancair sells. Mine has been on the 
shelf for some time, so I followed the instructions for reforming the 
capacitors (run for 15 min. at 75% of the normal voltage). If you use 
it for a 2-light system, you can set it up for simultaneous or 
alternating flashing of the 2 wing strobes. The specifications say 
that the unit outputs 22 joules each to the wing strobes and 44 
joules to the tail strobe.

I have found that if I set the system up for alternate flashing of 
the 2 wing strobes -- one strobe plugged into a "wing" receptacle, 
and one plugged into the "tail" receptacle -- the strobe plugged into 
the "tail" receptacle flashes noticeably brighter that the other one 
(same happens if I switch to the other "wing" receptacle). Is this 
normal? Apparently, you don't get 44 joules out of the "wing" outputs 
if you use only one of them. Is it normal when you set up this unit 
for alternating flashing to have one of the wing strobes flashing at 
22 joules and one at 44 joules, or is there something wrong with my 
unit? Thanks.
