my new diy grow light

yes and no.

that fuse will just pop. it's a 12v dc car fuse.

To explain, a 35v dc fuse at 10 amps is usually good for a 120v ac fuse at 10 amps.

a car fuse is specifically rated for dc. When used on an ac circuit it will MAYBE handle 60 volts.

Amps are the same at both volt ratings.

if you wire it right and ground everything, you will be fine. the only place you need fuses in on the incoming power line. it needs to be a 110-250v fuse rated at double your maximum amperage. if you are pushing 4 amps, you need an 8 amp fuse.

the more i look into it, the more i just think i will never use one.

So a fuse is pointless in this setup?

No, just more difficult than it needs to be.

There are fuses, but they need something to mount to. These are fuses for industrial or commercial equipment like convection ovens and dot welders. The only ones I have found need a housing like a box or small plate with a hole drilled and custom mounting. There is nothing high voltage that is inline.

edit: most of these even are designed to be mounted post transformer on 3 phase equipment. They are circuit board protectors.

Use google for 120v fuses.
