36V light bulbs

May 26, 2004 34 Replies

Wire 3 12-volt automotive bulbs in series. Sure sounds like your bulb is not really a 36V bulb (so bright) or else it's not made to take bumps. Something like 3 marker light bulbs would provide about the same wattage, and you know that they are able to take the bumps.

Some electric forklifts run on 36 volts. A forklift dealer might be able to supply a better headlight for your scooter.

put a diode or two in series with the bulb to lower the voltage. your problem will go away. Refer to standard equations for bulb life to understand why

To get a 10:1 increase in life (to 10 hours), the usually quoted 12th power relationship would require a 21% drop in voltage, or about 7 volts.

So with a few extra wires and a switch you could alternate the 'headlight' battery and re-balance the batteries.

OK, then make it four silicon diodes in series.

Ummm, Jim, I'm sure you realize that 4 x 0.7V is somewhat less than 7V.

Interesting part. I figured the TO-220 "simple switcher" might be easier for Charles to use in a one-off -- no circuit board.

I agree. ;-)

Tungsten filament light bulbs try to act like constant current devices. Unless you have a perfect match up, I would be _very_ surprised if the

6V bulb dropped 6V.

Do you have a part number and source for that?

See previous post. Also, go to

look at the various "simple switchers" they offer.

There is also a website that selects a part for you given your requirements at

then you can go to the "webbench" to get component values.

These things are dirt simple to use!

Oops, missed it. It will for a little bit, but not for long. It's a nice and easy first thing to check. Probably not very likely.
