Triac based Indecent lamp dimmer is a simple circuit and it doesnt requires additional power supply, works directly with 110V AC or 230V AC.
It is a low cost dimmer circuit for adjusting the light brightness of incandescent, Halogen Lamp, Light Bulb load up to 250 W.
Features:– Input supply: 230 VAC or 110 VAC
– Output: 250 W
– Triac controlled
– On board Potentiometer for adjusting level
– Power Battery Terminal (PBT) for easy input / output connection
– Four mounting holes of 3.2 mm each
– PCB dimensions 40 mm x 34 mm
“Indecent lamp dimmer” Lol?
Have you heard of my new band, Indecent Light Dimmer?

(Sigh. That’ll teach me to try to be funny on a forum with no edit/delete.)
I suppose the usual expression of “dirt cheap / dirty little” got lost in translation somewhere (possibly right at the non-native source) and became “indecent”.
Probably “incandescent”. I see Microsoft Frontpage in the tags. If there are no spelling errors, doesn’t mean there are no errors, hee haw.
Yes, that’s probably it… :)
These Electronics Lab posts are getting more and more ridiculous!
Now he’s just ripping off other sites – and being quite lazy about it. Didn’t even try to mask out the KEALABS logos.

I’m not sure I’d want to use it without some kind of heatsink at 250W, especially at 110v. Might get a bit more toasty than I’d want. There’s exposed mains voltage, and no safety warnings. The tab isn’t insulated either, so double on the safety warnings!
