I recently purchased one of the Inova X5's and just had
to make that 6 volt DB 4AAA Mod a (5) LED lamp! The Inova
is very impressive and I was able to pick up (5) brand new
white LED's from Tanners so all would be the same lot.
I layed a quarter on a piece of perfboard and outlined it
on the material. Then cut out circle with small pair of dikes.
I found what was to be my two center holes and proceeded to
lay out the 5 LED's so all would have one leg coming through
one of the center holes. Soldered them all together and detached
all but one leg to use as one of the lamp contact pins. On
the back of the perfboard I ran a ring of wire around the
outside LED legs and soldered all to this wire. I just used
one of the cutoff legs to solder to the ring wire and it went
through the other center hole. Fun part was getting these
2 legs in those tiny lamp contact holes when you can't see
what you are doing. The perfboard now blocks your view! Hold
your mouth just right and lift your left leg off the floor
and you'll eventually poke it in the right place. I tried
running at a straight 6 volts but with new batteries one of
the LED's started to turn slightly blue and I know what that
means. Quickly turned it off and took out a new battery and
subbed one that wasn't totally new . All LED's did fine then.
I am going to go back and add a 5 ohm resistor to one of the
legs to limit current so I can use all new batteries at once.
I was attempting to recreate the Inova X5 brightness with
the DB and I have surpassed it! Witha 5 ohm resistor they
should be about equal brightness.
