Hi Big Greg, welcome to the forum. If you are after a lighter Dingotone colour Dingobass can mix you a lighter version of a colour or he should be able to include an extra bottle of a reducer to mix in to lighten the colour.
Once you put down a full strength coat it will be hard to lighten the colour. Generally you keep applying coats till you are happy with the colour. It would be best to start off light and build up to the depth of colour you want. It's easy to darken the colour but once a full strength coat is on hard to make it lighter without sanding it off. Hope this makes sense
EDIT I just asked DB and Dingotone doesn't ship to USA yet, sorry. You could look at other stain options
