Making a dimmer switch?

Hi all

 

Posted this in the equipment section, but didn't get any responses, so let's try here...

 

Just bought a Deben tracer mini lamp. It only has an on / off switch, so I was looking at getting a dimmer for it. They seem to go for about £35, which is more than I paid for the lamp! Is it possible / easy to make up my own dimmer switch with a rheostat and bits from Maplins, or is there a bit more to it than this? (I seem to remember seeing something about how the dimmer does more than just reduce the current to the bulb (runs the lamp at a lower voltage? :/), but can't remember the details...)

 

Cheers.

It says in the op he wants it for a Deben tracer mini, which i beleive is not a led but a bulb, in the specs of the dimmers shown it states they are for LED's, so will these units work on a bulb ?

 

 

The link I provided is the same dimmer switch that I use for my Blaserlite & Lightforce, which have bulbs fitted in them.

Thanks for the suggestions, all. Good to know that a basic dimmer switch will work. Do the dimmer units get hot? Do they get rid of the excess current as heat?

 

I assumed a 240v house unit would not be suitable, but the ones from Ebay look good, if a bit big!

 

Cheers again.

 

 

A house dimmer switch won't work. The dimmers that I have mentioned, don't overheat, and I can't see any difference with power consumption.

What a mate and I did was to buy a Velcro pack and fix the opposing parts to the side of my battery carry pack and the dimmer. Made up the wiring link and can attach it to the side of the bag. Work out what way you need it set up before sticking the Velcro strips!!

The dimmer can be taken off if it is not needed…..
