First, you mean Lovibond, not SRM. SRM is used to measure beer
color. Degrees Lovibond are used to measure malt color.
Second, your numbers are meaningful only if you're talking about Briess malts. Other maltsters have different specifications for Roasted Barley. Simpson's, for example, lists their Roasted Barley at 1300 EBC, which is roughly 500L.
More confusingly, many maltsters, including Briess, use proprietary names for their products which make it difficult to make intelligent choices when substituting ingredients. Makes sense for them, I suppose; it takes some experience and detective work to assure yourself that Simpson's Roasted Barley and Briess's Black Roasted Barley are essentially equivalent, but the Simpson's Roasted Barley and Briess's Roasted Barley are not at all alike.
