So you are not going to be left blind at the worst possible moment by a blown fuse (they will ALWAYS blow at the worst moment), maybe you should consider fusing each side separately.

Hi Syncro, Model A globes are rated in CP (Candle Power) which is a measure of Illumination. Example 50 CP. It is an older method of categorizing globe performance/brightness. There is no way to use CP in the use of Ohms law parameters.
