any small electronics sparks here?

Hi. I want to know if it would be possible to adapt an 18million candlepower search lamp so it has a dimmer switch as they don't make them with dimmers. Its 12v DC. I'm not bothered about it having a rough finish as its only for me when I'm shooting pigeon and rabbit at night for local farmers
Cheers.

Is it just a filament lamp? If so a variable resistor rated with a suitable wattage would do the job.

How small does this electronic spark you're looking for have to be?

Maybe place an ad in the Jobcentre after the panto season ends??

whats the current draw/wattage?
you need a simple pwm dimmer
search for "dc pwm" on ebay, plenty of results.

As Rob said, a suitably rated variable resistor in series with the lamp will do the trick.

This has somehow reminded me to fire up my minature Jacob's Ladder again.
15,000 Volts, no worries! :smilielol5:

I take it you're looking at 55/60 watts? That's a hell of a size of variable resistor and you'll need it on a heat sink to dissipate it's heat.
I've seen led torches/headlamps that are dimmable that have a 100m range, would that not be suitable?

I was just about to post a picture and some more details and realised that it has two settings one for 5million candlepower and another for 18million candlepower. I should learn to "look harder" at ALL the details! Sorry to have wasted your valuable drinking time chaps!

Get a Ledlenser X7,adapt it to your weapon,it has several features,including half power dimming. I have one for the fox job,it is comparable to lamping kit of yesteryear,but is tiny.
Failing that,camo-up,and face your quarry in daylight,like a true hero...:icon12:
