The technique often cannot pinpoint the date of an archeological site better than historic records, but is highly effective for precise dates when calibrated with other dating techniques such as tree-ring dating.

Relative dating can only give the date within a million years or so, while absolute dating can give the exact date to within days. Careful sampling under dark conditions allows the sediment to be exposed to artificial light in the laboratory which releases the OSL signal.
