Need A Fuse Asap!

[miNiChher]

My ballast for one of my metal halide's went out... and my coral is in desperate need of the lighting! I finally figured out that I blew a fuse in the ballast... a 5x20 F8A Fuse to be exact....

Anyone know where I can locate this small but very important piece of... for my ballast?

Ace hardware, Home Depot, and Lowe's do not carry it... =( I don't want to have to wait for something to come in the mail either, but if that's my only hope then so be it!

Taking a guess here ... 5 X 20 mm fuse , fast acting, 8 amps. Should be a voltage rating on it as well, probably 250 volts. It should be a pretty common size available at Radio Shack. Maybe an auto parts store as well, but probably not.

Radio Shack didn't carry it either =(
