a neon would work well. you might be able to scavenge one from an old surge strip, some have neons in the light up power/toggle switch.

the kodak max circuit seems a little fussy when trying to light my 8W fluoro, but it lights a neon no problem. i have no led christmas lights to try.

You can put a single LED in place of the tube and it should light. At least that works for me.

here is the pic of my coil and my diode i spoke of earlyer 

i will not blow any more fets!!!

ist!

the rateing on the diode is 600v 220a  continous x2  and can peek much higher ....  so each one can handle HUGE POWER.... CLOSE TO 120 000 W

lets do the math  600v x220a =  132 000 w x 2

i guess that means......   264 kw

if i get 3 more diodes...  that would mean i could have a 1mw unit   

hummmmmm......

Wow,  Bill - way to go.    Just think of all that wire that AA Fuji circuit had to go thru to light these 400 LED's.  I would think if they were all placed close to each other on a circuit board you could light 500 with no problem.  I am really amazed.

@ maw2432:

Thanks!  So am I. (amazed)  To hook up all 4 strings of 100 leds each in parallel, I had to use 8 test leads of various lengths.  One thing I do not understand (well, there are many things I don't understand) is why polarity does not matter with these diodes?  I can hook up the power leads from the Fuji board either way and it still works.  Is this because we converted to ac?  I guess that would explain it.

I agree.  If we had a large enough proto board, I would bet 500 would light up.  Plus, I believe it was xee2 (I can't go back and check while posting) that said he ran his Fuji AA board at 3 volts input.  With that power I would bet 500 would light up just fine.
