RE: (ET) DC to DC (36v bulb source)

["Chapin, Tim" <tchapin umich edu>]

I picked up the 36 volt head lamps bulbs from a lift truck dealer.

Here are some old emails on the topic

Hello group,
  I purchased some 36v dash bulbs from Radio Shack. Part number:
RSU-11385994.  They were 79 cents apiece. I bought four to make it worth 
the
shipping costs. They do not carry this bulb in stock so you will need to
order it at the store or call 1800-442-7221 and order them over the phone.

Another slightly different approach.  If you move the battery tap from B6+
to B2+ you change the lighting voltage from 12v to 36v.  Then from the
schematic the headlights and dash light are all currently in parallel.  So,
you can use the 36v bulbs for the headlights and put a resistor in series
[R(s)] with the dashlight bulb to keep it at 12v.  To do that, just measure
the dash light's resistance [R(dl)] - then:
 
I(dl) = 12 / R(dl)
 
R(s) = 24 / I(dl)

Hi all

I have been playing with this idea also.

I found http://www.golfcarcatalog.com/merchant.cfm?pid=1334&step=4
A driving light style from GE in 36 volt DC.

And numerous flashlight bulbs in 36 volt.

Where is a good place to find these 36v bulbs?

As for the 36 to 12 converters, you can buy 36 volt bulbs that fit right
into the original sockets on the elec-trak (my project for this summer for
my e-12m).  So now you are down to just the 18 volt for the lifts.  I would
think someone could come up with a better actuator that would work on 36
volts.  Maybe something like the dish actuators.  Most of them are rated at
500 lbs.

Hi
Before we drop the tread. What is the current required for the
headlights and the lift be. I am asking this because I found a source of
DC/DC (36 to 12) and (36 to 18)  converters that cost between 75 and 150
dollars. This may be too rich for my blood to-day. But, I can dream.
