I've done the search, read through a bunch of topics, I'm still confuse on what fuse value should I get.
I know I need a slow blow fuse, and that's about it. I also read couple topics saying the fuse value in the lumenlab instruction is wrong, and the fuse value should be about 6A 250v instead.

So which fuse from Radioshack should I get? I'm using the S51 ballast from atlantabulbs btw.

thanks

speaking of atlantabulbs, they sent me the Ushio with broken glass fragments inside the light bulb

This is the fuse you want.
This is the fuse holder you want.
Hope that helps!

Why note just get a 5AMP push-to-reset fuse block and attach it to the project box next to the main switch. That way, if it blows, its a quick fix to reset it. You dont have to mess with opening up the box.

We sell the 5a circuit breakers in the store.

sweet, thanks WaterFowl
