   I wonder, if I fed the lamps with mains voltage DC, simply a bridge rectifier   
   and a huge capacitor, they'd reduce their flicker.  The cheap shit LED lamp I   
   have that actually flashes at 100Hz would most likely get much brighter and   
   burn out, so I'd have    
   to adjust that, but the others which only flicker 8% would just get 4%   
   brighter.
