Anyone use DC (low voltage) in the shop?

I recently added an ex-PLC enclosure.. you know those hoffman type boxes with the rail mounted components inside? I've been carrying around a railed 24v PSU for years now with no real purpose until now.
So I tossed it into the box behind a big chonky controls-type on-ff switch.. why? Well I got a pretty sweet deal on 12-24vdc 4 LED spot lights, the cheap ones you see on Amazon. I setup two with a PIR sensor at the far end above the doors, and wired the other two to provide switches light outside the main doors. It's not uncommon for me to be working on something with those doors open but not pulled underneath the roof.

Will probably be weird to a lot of folks but I had the parts and it serves a purpose.

Not as a power standard for the shop, no.
But I have more DC power tools than AC power tools. Shop PV is DC, We have large DC battery banks for business (48V) standard, all the RVs (now lithium) are 12V DC.

POE is DC. DC runs the wifi network, security, all of it and has a battery backup.

Ooo the idea of DC power tools is pretty neat. I had no idea anyone made such a thing.

I do. All the time
Buy 220 V LED strips for work table. Great illumination. With 3 units 0,8 m above table no shadows at all
Throw out the RF generating chopped 220 VAC to 158 V DC garbage converter.
They radiate RF up to 8 MHz, making sensitive electronics, such as radios, impossible to repair.
Install capacitors and diode from 220 V AC and run them on clean filtered 158 VDC. ( cap around 1,2 µF)

The worst offender, however, was a RIGOL $ 550 120 MHz 2-channel scope.
The scope generated high harmonics up to 45 MHz. Great design.
Sold it for $100 after 2 weeks, with a note " NOT SUITABLE FOR ANYTHING BUT 220 V AC CIRCUITS"
