Dimming "Switch"

ello people. im nearing completion of my 8 x 4 x 4 tegu viv and im running a tube heater to keep background temps up and an AHS for the night time temps (this stays on and just kicks in if it gets cold).

I want to be able to control my basking temperature manually because if the bulbs are on a stat it may become difficult having a secondary heat source like a tube heater.

I bought a normal household dimming switch and fitted it to my bulb to test out the wiring. I wired it up like on the diagram (I think!) and when I turned it on, it doesnt dim. it just stays on full blast all the time.

I split the live cable and put it in either ends of the dimmer and left the neutral cable connected.

just to clarify the dimmer is a "eddison" dimmer switch and im running one 120w PAR38 bulb off it using a ceramic fitting. its all wired up with 0.75mm 2 core wire and attached to a plug with a 13amp fuse.

any electricians out there who could help me out i would greatly appreciate it!

All the best

Tom

I suspect you may have wired it incorrectly, most dimmer switches are 2-way but can also be used as 1-way switches (which is what you want).

You should have three terminals at the back marked L1, L2, and Com (or Common).

You should use L1 and Com, ignore L2.
