Sorry, I think this maybe a bad idea. Running high wattage through the light fixture wiring is not a good idea imo.
Never seen a 1500w light bulb

and light fixture wiring is typically thin, not to be confused with thhn wire.
Don’t forget the lack of GFCI too.
To defend Silentdrinker, maybe he didn't pay sufficient attention to Jayjay1976's particular comments about his setup, but I think his general comment is valid. If you're going to use 2 110V heaters, you just need to be sure that you have 2 outlets on separate breakers. Sounds like this is a pretty common occurrence in most kitchens.
I did see that. I’m not challenging or questioning his method. There’s nothing wrong with it as long as it’s properly done. My comment of “hopefully” was in general for those who think they can follow this advice with out verifying their electrical simply because someone has tried it and it worked fine for them. And that kind of mentality of, ‘he did it, so it must work,’ is strong within this community.
A lot of old houses wouldn’t be setup the same. Plus I imagine a lot of them lack ground fault circuit interrupters and that’s really important for electric brewing.
People blindly follow advice and some people give bad advice, like using a light socket, or neglect to provide the full picture. I’m not saying he’s giving bad advice; he’s not. It’s just lacking some info since his electrical is to date and even beyond the minimum requirement with the 10/3 wiring.
I know there are people who assume overloading a circuit means plugging too many things into one outlet. They don’t realize it’s not about the quantity of devices or the receptacle that matters. Plus they have no idea what a GFCI is and how important it is for safety. The wire shield on the element can easily crack exposing a live wire with out detection until it’s too late.
Hell, look at how many people burn their house down each year trying to fry a turkey. And that’s a relatively straight forward common sense sort of thing.
Electricity is dangerous as it is, adding water increases the danger. And using unorthodox methods to avoid properly powering your electric setup could increase that danger further. Ghetto setups aren’t uncommon, but it’s less of an issue when it’s a ghetto ferm chamber or fermenter.
